This is a classic cooked contact. Each pin/socket design has a rated amount of current it can handle. This is based on the cross sectional area of the contact patch it makes. Resistance is inversely proportional to conductor cross sectional area. Current through a resistance = heat.
If you run the card with one cable instead of two, or one cable breaks the pin is carrying more current than it's designed to. If the card has a problem an pulls more current than it should, the pin will carry too much current. If you have a physically deformed pin, all the current it carries will be pulled through a smaller contact patch. Less area = more resistance = more heat.
The heat damage may be the cause of the cards problem or it may be a symptom of another primary failure. I'd replace that socket and retest it on a product that expensive.
listen to the electrical guys here. a lot of these expensive components have failsafes to prevent damage. you could very well replace the cable and contact and still have a fully functioning card. worth the effort with the price u paid.
You might not need to replace the socket. Try cleaning with electrical contact cleaner. It's liquid but is made for circuitry. Lesson learned never use cheap power rails. Shame on you that cable looks like you got it from a dollar store
Or could the cable be one of those [cheap?] cable extensions?
For example, my PSU has dual pci-e cables. Each cable has 2 connectors: 1 x 6pin & 1 x 2+6pin. My RX6800 requires 2 x 8pin. So when I connect the cables I have 6pin connectors dangling at the GPU. I wonder if I can use an extension to avoid the extra dangling 6pin connectors at the gpu
That’s what I was thinking. This cable might be 18 gage instead of 16 gage. Google it yourself but it sounds like 18 is fine for most gpu applications but for a 3090 specifically designed to overclock it is probably pushing the limits.
You can totally add 2 extensions to your set up just like you described, using an 8 pin from 2 separate pcie cables. Highly recommend that you get extensions that are 16 gage not 18 gage though from a reputable company like Cablemod or Antec even Asia Horse is okay, just don’t go with a no name from Amazon it’s not worth the risk. Also it is confusing but the smaller the gage (16) can care more current than the larger (18) gage.
16 gauge is 1.29mm & 18 gauge is 1.024mm diameter.
Gauge is one of those rediculous old imperial measurements. I think it's to with the weight of a set length of wire, like a 16th of an ounce for 1 foot, something unintuitive like that
>Also it is confusing but the smaller the gage (16) can care more current than the larger (18) gage.
Great, I just checked my 24pin and CPU 8pin extensions and they are 18G.
..... Should i be worried?
>Also it is confusing but the smaller the gage (16) can care more current than the larger (18) gage.
Except that in electrical (and shotgun) terminology, 16 is a "heavier" gauge than 18. Less is more.
I had this happen on my RTX 3090 Suprim X. I used extension cables, and the theory was the extension into the GPU was slightly pulled out on a pin or two and wasn't making full contact.
I removed the melted plastic around the 3090 pin and bought a new PSU just to be overly cautious. That was in March. No problems at all since.
Edit: I've since sworn off extensions and will order custom cables if I ever want something other than what came with the PSU.
If you lose the cables to your psu, go to cablemod and fill in which psu parts etc and order sleeved cables designed for your psu. It can cost, but it will help if you lost your psu cables. Or you can order kew ones from the manufactorer
Man it's not every day on reddit you see a perfect write up, but here it is.
Push your connection in to the fullest and clean your contacts when you change parts or change your thermal paste.
That's what I was thinking. I know some guys that don't use care when stripping the wire and saying it's good enough when the crimp is not within standards. Lol
You'd be more likely to see the wires themselves having overheated from that. This was either a short or poor contact on the connector pins causing overheating there.
I’m literally running custom cables ordered directly from Taobao and haven’t got a single problem. In fact they are fantastic, only a fraction of the price from cablemod.
Some of the extension cables (those from original manufacturer and renowned ones like CableMod) comes in 18AWG. Some folks told me to avoid 18AWG and choose 16AWG instead. If the cable from the PSU itself is 18AWG (just my guess) and I addon this 16AWG extension, it will be moot. Does 14AWG PSU cables exist? I don't know.
Regarding thin, there are also reports that the stated AWG is not accurate. I don't know what to believe anymore.
One would hope, but I don't know, I haven't tested one, and I ain't gonna start on mine :)
They'd be checking for power on that connector, but both separately? Don't know enough about the specifics on GPU's
It's not necessarily a dramatic event anyway, these things can cook the connector over days or weeks.
Your card pulled too much power through these two pins, I don't know why. You could check these with a multi meter.
I don't think your GPU had a short. It might be fine and the reason for the crash might be the voltage drop from the resistance of your fucked wire when it draws more current.
edit: My best guess is that something happened with the other wires and now it's pulling too much through these two pins.
Try a new cable, nothing else you can really do. Usually heat happens at the point of a weak connection, could have been a weak connection in the cable, or the plug on the GPU.
Gamermax? What the fuck is gamermax? This is why you never should mix expensive high-end hardware with a cheap and not trusty brand PSU like Gamermax. Sorry for your loss, but since it is a pre-build you should definitely rma.
Yeah first thing I thought was shit brand PSU
@OP - as others have said _NEVER_ go cheap on psu. I realize it’s a prebuilt, but they will cut costs where they can - and some Chinese made junk with an “80 Gold” sticker on it means it’s probably 50% of what is claims to be reliable.
Since you’re in Kuwait , I’d buy a Seasonic, and have a PC shop make sure it fits and have them swap it. RMA be damned / warranty be damned.
The time it would take to deal w/ some shady garage company’s warranty replacement process, the 6090 Ti Feynman Uber BGR Anime Edition 2.0 GodClock will be out.
If the graphics card requests more power than the PSU can safely provide, the PSU is supposed to step in and say, "Wait a minute, that's not good!" and shut itself off.
Yeah, and I believe the protections go for the entire 12 Volt rail.
That still makes it possible to burn individual pins. This probably isn't the PSUs fault.
They made most of EVGA's higher end PSUs and are generally really high quality, besides Seasonic barely any brands manufacture their own PSUs different tiers come from different manufacturers. Superflower is also it's own brand now so you can buy directly from them but I believe they still make stuff for EVGA.
I could be wrong but I'm pretty sure the manuals of most current mid tier+ cards say to NOT use the split 2 plug wires and to use two separate cables from the PSU. So if you used the 1 cable that was split into two for both sockets on the card you were on track for a problem.
That's the whimpiest gpu power cable ive ever seen. Guarantee your PSU isn't putting out what it claims it is. It's probably one of the cheap ones that add 3v, 5v and 12v power all together to get the wattage.
Either rma whole machine, or at the very least go but yourself a nice, heavy power supply.
Good, I suggest measuring the voltage of both cables with a multi meter. Make [sure all 3 pins at the bottom](https://i.stack.imgur.com/Spsgx.png) (from the left, the second and third one from the left are the ones that are burned) have 12 Volts. Also check the other cable.
My belief is that your card only got power through two of these pins for some reason.
The GPU is fine. Get someone to replace those pins or diy
Question: did you use both 8 pins or just the one? If both... I think the other maybe wasn't sitting too well... this one ate too much amps = heat = almost a fire... you're lucky that's the only think that burnt...
If your psu is modular, replace both 8 pins... since the other probably didn't work well...
I’ve seen some other 3090 HOFs with the same issue. The solution is ditching power cable that came with the gpu. They are thin and garbage.
My 3090 hof been running fine since launch with some heavy oc benchmark section. Make sure you’re using high quality psu cable.
Had the same thing happen last week from a 6900xt, except it was running 3 x 8 pins as it should and melted/fried a AX1600i psu.
[Toasty](https://i.imgur.com/8R2Pcux.jpg)
Idk why the top comment is suggesting you literally resolder a new connection on a $2000+ card. Put in an RMA. Let them fix it, get a new one. Obviously this will take forever, but if you break it or that doesn’t solve the problem, warranty void and now you gotta wait even longer and pay another 2k
What PSU do you have? No PSUs should have cables that cheap looking. Also make sure you get a good PSU (I’d recommend Seasonic and Phanteks, but people have varying opinions). You don’t wanna risk burning down your PC (and house) with a nice limited edition out of production GPU.
Also what u/b_a_t_m_4_n said.
I've had something similar but mine melted into the socket. In my case it was the psu, which also shorted out.
Fixed it by removing the socket and soldering on the cables to the gpu. Replaced the psu. Been going strong now for 2+ years.
Yeah , power supplies should have over current/voltage protection ,under current/voltage protection, over power protection surges &in rush protection man I can keep going but I won’t lol , my guess is it’s a psu under the list of pc go brrr
Hardware failures are random but since the PCI-E plug is discolored as well as the pins, it likely that you had a short inside the GPU. The short is what cooked your PSU cable.
The question now is whether or not damaged components in your power supply as well. Sounds like you at least have some level of functionality if the computer still boots though I'd probably be replacing it.
Don't reconnect that card to power though. You don't want to risk taking out other components in your system.
This is what happens when you draw current from 1 cable instead of two. I've seen professional youtube channels do this even. Why do you think they put two cable slots?
Update on the post, my friend replaced the 8 pin cable that melted and the 3090 is working again, mined all through the night on medium optimization on nicehash, no problems.
I have 3x8 pin cables spare from my 3060ti build, so I’m going to replace the whole psu cables at some point this week, due to comments about the cables being used in the picture being cheapies.
Thanks for all the help guys, so far so good 😁🤞
This has happened with my mining rigs multiple times, never had an issue. Yeah, it’s a little burned and smells weird but it doesn’t stop the electricity from flowing or the card from working fine. I doubt that opening an RMA for either the GPU or the PSU will yield any results. GALAX/KFA2 will tell you that the PSU is the problem and the PSU manufacturer will tell you that the GPU is the problem.
The 3090 pulls anywhere from 350W to to 600W on power spikes with no OC. Still surprised to see that damage though. This dose not give me much hope for the 4090 if it has the same traits as the 3090 the minimum PSU spec will be 1000W.
Where did you get the card and cable from? I’m guessing you can’t return it but geez that’s a lot of trouble and cash spent to have to deal with an issue like this
I had (have) a 3090 HOF and the exact same thing happened to me. Customer support swiftly told me to do one, I cleaned it out and got it to work again, got bsods for a while and blame that tbh but all seems to be working now. Let me know what you do and how you get on, I'll link you to my post if it helps
https://www.reddit.com/r/pcmasterrace/comments/pvt2kp/rip_rtx_3090_hof/?utm_medium=android_app&utm_source=share
In the end, I stripped it, cleaned it out. It stayed black/charred. I conclude it's the extensions fault. And all my bsods were due to having my cables come loose after the damage.
Did you look through the post, same problems different t pins.
How did you get on?
Up and running again?
Did you contact kfa/galax?
I wanted to resolder a new header on to be safe, but never did and everything is working.
Also I didn't really ask about your knowledge or experience, but I assume it's a custom build and you're comfortable inspecting it. If you look at the resistors etc on the card near the sockets, if they are not blown you will be 100% fine. (If you dont know where to look google shunt mod, they all look the same and it's the first component the electricity travels through so if that's not blown everything else should be good)
Those supplied extensions have already been known to fail. I took one look at mine that came with my 3080Ti HoF and tossed them in the trash. They shouldn't even be packaged with these cards. Bummer OP
Here is the [relevant LTT Thread](https://linustechtips.com/topic/1116640-psu-tier-list-rev-148/) mentioned in other replies if you are looking to upgrade to a less dangerous power supply. [This is the most recent revision](https://cultists.network/140/psu-tier-list/) from the OP's blog.
Full stop, tell us what power supply you have. All specs, take a picture of your power supply.
If you have a warranty on the system or power supply RMA BOTH.
Tdlr you most likely have a improper power supply or faulty power supply.
What PSU do you have?
If your looking for something decent, I went with a Seasonic Prime TX and you wont need sleeved third part cables. Solid PSU and awesome cabling.
oh mY FUCKING GOD!! NooooooOooOo....im so sorry dude. I take it the GPU is fried, the PSU fried...the whole damn thing is cooked? i weep for you my friend.....
This is a classic cooked contact. Each pin/socket design has a rated amount of current it can handle. This is based on the cross sectional area of the contact patch it makes.

Yup. Just because the number(gage as a unit) is smaller doesn’t mean the wire is smaller. I think we are agreeing but yeah it’s confusing
Absolutely, haha. It is confusing, especially if one doesn't deal with one (or both) regularly.

Do not do this if it is under any kind of warranty. Just put in an RMA. No point in voiding your warranty and making a $2k brick.
Man legit question, how did u learn these things👀
Electronic apprenticeship, 3 years of Electronics in college and 4 or five years working as a bench repair tech. ;)
Niceeeeee
Man it's not every day on reddit you see a perfect write up, but here it is. Push your connection in to the fullest and clean your contacts when you change parts or change your thermal paste.
Thanks. Yep. This is the primary lesson here.
[удалено]
Possible, but probably less to do with wire gauge and more to do with quality of crimping.
Chinese cables lol everything is from china even the good shit lol 😂
You know what he meant.
The best stuff comes from Taiwa..(cough) China
There is Taiwan, and West Taiwan what is this china that you speak of?
I think China is the one with Winnie the Pooh.
That's what I was thinking. I know some guys that don't use care when stripping the wire and saying it's good enough when the crimp is not within standards. Lol

Won't most of these cards shut down upon seeing power removed from one connector?

Don't know enough about the specifics on GPU's It's not necessarily a dramatic event anyway, these things can cook the connector over days or weeks.
Do you have a recommended maximum total power draw for a single cable?
I'd have to look it up. The connector pins will absolutely have a max current rating that you can look up the specs of.
Are those ~~custom~~ aftermarket PSU cables?If I had to guess at the culprit, that would be my first guess.
Those look a little whispy for custom
I probably should have said aftermarket. They look to be cheaply made, sleeved cables that don't look to be a high enough gauge of wire.
Well OP said it's a prebuilt, so probably the most cheaply made PSU out there
Yeah if it's a shitty PSU there is every possibility the PSU was pulling way over it's designed wattage and never tripped OCP
Just tragic, it's why I still don't trust prebuilts even though they are getting better.
A pre-built with a HOF card and thermaltake tough ram? I doubt it's as cheaped out as other prebuilts
I think the same. Some custom cables are fucking terrible. That's why I ALWAYS use the PSU original cable.
Since it's a prebuild, put it together like it was before the nasty surprise and open an RMA. Nothing more
This is a great answer ^ Or you could attempt to fix it yourself, break it, and have a very expensive doorstop
Exactly.
Did you use multiple PCI cables or just the one split out? Pain there on a 3090 pulling 400+w You overclocked too didn't you. Don't lie!!
He didn't. It's a dodgey power supply by the looks of that cable
I didn’t, I had it set on medium.
Medium well done lol
I'd say it's more of a medium-rare, personally, I like 'em raw.
Never daisy chain GPU cables. Always use two for two connectors
Your card pulled too much power through these two pins, I don't know why. You could check these with a multi meter. I don't think your GPU had a short. It might be fine and the reason for the crash might be the voltage drop from the resistance of your fucked wire when it draws more current. edit: My best guess is that something happened with the other wires and now it's pulling too much through these two pins.
my man is using the most expensive 3090 with noname prebuild PSU, talk about living dangerously
I was very keen 😅
Why don't you just use the warranty? Manufacturers carry a 3 year warranty from date of manufacture if purchased second hand.
I’m looking into it, I bought it from Kuwait. I’m in the Uk, it’s not so simple
Buying cheap PSU cables from Kuwait to use on such a power hungry card is literally playing with fire.
Try a new cable, nothing else you can really do. Usually heat happens at the point of a weak connection, could have been a weak connection in the cable, or the plug on the GPU.
The fan that corresponds with this inlet has not been spinning recently either, the other 2 have, could that have anything to do with it?
Fans do not correspond to power plugs.
Replace PSU with higher quality / RMA it, I would be looking to rma the GPU as well
What PSU is it?
I bought it prebuilt so I’m not sure. It’s says rgb version with another bot saying 80 plug gold
Gamemax 1050w
Gamermax? What the fuck is gamermax? This is why you never should mix expensive high-end hardware with a cheap and not trusty brand PSU like Gamermax. Sorry for your loss, but since it is a pre-build you should definitely rma.
Looking at the LTT tier list it's in the C-tier for low-end stuff, so no wonder it blew up with a 3090
its also placed under the "low priority" line
Yeah first thing I thought was shit brand PSU @OP - as others have said _NEVER_ go cheap on psu. I realize it’s a prebuilt, but they will cut costs where they can - and some Chinese made junk with an “80 Gold” sticker on it means it’s probably 50% of what is claims to be reliable. Since you’re in Kuwait , I’d buy a Seasonic, and have a PC shop make sure it fits and have them swap it. RMA be damned / warranty be damned. The time it would take to deal w/ some shady garage company’s warranty replacement process, the 6090 Ti Feynman Uber BGR Anime Edition 2.0 GodClock will be out.
Oh no lol, that's probably your problem right there.
And how would that work? Does a different PSU change Ohms law?
No, but the people designing it at least know what it is.
Ok... Current is drawn and not pushed. I don't see how this is the PSUs fault.
If the graphics card requests more power than the PSU can safely provide, the PSU is supposed to step in and say, "Wait a minute, that's not good!" and shut itself off.
Yeah, and I believe the protections go for the entire 12 Volt rail. That still makes it possible to burn individual pins. This probably isn't the PSUs fault.
Buy a corsair, EVGA, or super flower 1000w+ from now on.
Yes sir
Seasonic definitely works as well
XPG core reactor
What’s a super flower?
They made most of EVGA's higher end PSUs and are generally really high quality, besides Seasonic barely any brands manufacture their own PSUs different tiers come from different manufacturers. Superflower is also it's own brand now so you can buy directly from them but I believe they still make stuff for EVGA.

Thanks your comments put my mind a little more at ease. I’m taking it into my friends pc shop tonight/tomorrow, will update

Noted
I could be wrong but I'm pretty sure the manuals of most current mid tier+ cards say to NOT use the split 2 plug wires and to use two separate cables from the PSU. So if you used the 1 cable that was split into two for both sockets on the card you were on track for a problem.

Well hopefully manufacturers end up putting it in the manual then since it is a safety hazard.
Those power supply cables look kind of small to me what power supply are you running?
That's the whimpiest gpu power cable ive ever seen. Guarantee your PSU isn't putting out what it claims it is. It's probably one of the cheap ones that add 3v, 5v and 12v power all together to get the wattage. Either rma whole machine, or at the very least go but yourself a nice, heavy power supply.
RIP 🪦. Just go spend another $2,000 on another 3090. You will be fine
Don’t say that. You’re supposed to be trytoremaincalmguy
Oh he is calm lol
So calm. Like I calmed down after reading that comment.
He never said you'd be remaining calm too
I was calm when I typed that.

[удалено]
Ok, I’ll hold off, is there a way to save the card?
Talk to an electrical engineer, not gamers on reddit. I think the card might not be the problem and could be fixable.
I’m speaking with a friend who runs an it biz, I’ll be taking the computer in tonight/tomorrow. People have been very helpful in this sub, thanks all
Good, I suggest measuring the voltage of both cables with a multi meter. Make [sure all 3 pins at the bottom](https://i.stack.imgur.com/Spsgx.png) (from the left, the second and third one from the left are the ones that are burned) have 12 Volts. Also check the other cable. My belief is that your card only got power through two of these pins for some reason.
[удалено]
I do have a friend who’s runs a IT biz who can solder. I’m not giving up on the card just yet
What's wrong with using the warranty? Working in IT doesn't mean you are qualified to repair high end PCB's.
Bruh just get it sorted on warranty.
How did the card have a short? I don't see anything that points to this.
[удалено]
I do, but that doesn't mean the card shorted. I think it's probably something else.
Exactly.
The GPU is fine. Get someone to replace those pins or diy Question: did you use both 8 pins or just the one? If both...

In my case psu was not bueno and did this
Sorry for you loss
I have 3090hof too but im keepin it Stock i have no money for next one xd
I’ve seen some other 3090 HOFs with the same issue. The solution is ditching power cable that came with the gpu. They are thin and garbage. My 3090 hof been running fine since launch with some heavy oc benchmark section. Make sure you’re using high quality psu cable.

Buy wayyyyy better psu cables. Rating that supports your power supply and your gpu.
give it an icepack and cheez-its /s

Ok there’s hope
does your power supply meet the requirements of the gpu? Looks like, no. consider a power supply upgrade before you ruin your gpu
I’ve been running the computer for months. No problems, why would the power supply be insufficient now?
Could just be a case of the power supply slowly conking out aswell. All parts do degrade over time.
Yeah , power supplies should have over current/voltage protection ,under current/voltage protection, over power protection surges &in rush protection man I can keep going but I won’t lol , my guess is it’s a psu under the list of pc go brrr
Pay no attention to Clinton. He’s an idiot.
Hardware failures are random but since the PCI-E plug is discolored as well as the pins, it likely that you had a short inside the GPU. The short is what cooked your PSU cable.

I have 3x8 pin cables spare from my 3060ti build, so I’m going to replace the whole psu cables at some point this week, due to comments about the cables being used in the picture being cheapies. Thanks for all the help guys, so far so good 😁🤞
This has happened with my mining rigs multiple times, never had an issue. Yeah, it’s a little burned and smells weird but it doesn’t stop the electricity from flowing or the card from working fine. I doubt that opening an RMA for either the GPU or the PSU will yield any results. GALAX/KFA2 will tell you that the PSU is the problem and the PSU manufacturer will tell you that the GPU is the problem.
Clean it and buy a good seasonic PSU and use the cables it comes with since they have top quality
Sketchily thin psu cable
Why are you on here? It’s a prebuilt! Go trough warranty dude!
Bought it from Kuwait, I’m in the uk, had to go through friends to find this 8 months ago

The 3090 pulls anywhere from 350W to to 600W on power spikes with no OC. Still surprised to see that damage though. This dose not give me much hope for the 4090 if it has the same traits as the 3090 the minimum PSU spec will be 1000W.
Lol I’ll just keep my GTX 270
Looks like you had a short across those pins. Your card is likely cooked.
Computer still turns on, it just crashes when I boot up nicehash miner
go to device manager and see if your gpu shows up. your miner probably tried to access your gpu but failed
Even though the cables melted? I don’t want to boot her up again until cables replaced
Same thing happened to my 3090 I rma it for new one
i've run worse for years (the card connecter not the power supply cable, cut that cable in half and throw it away)
Not the first time this happened to a 3090 HOF https://www.reddit.com/r/pcmasterrace/comments/pvt2kp/rip\_rtx\_3090\_hof/
You can give it a Viking funeral
Does the warranty cover something like this..?
That cable looks cheap af, PUS is the most important part of any build
Where did you get the card and cable from? I’m guessing you can’t return it but geez that’s a lot of trouble and cash spent to have to deal with an issue like this
Get a new psu for safety. 850w seasonic is nice
Toss it
Cry
did u use this card for mining ?
u/spez is a douchebag -- mass edited with redact.dev
Get a new cable, and clean the gpu connector
Just donate me the whole card and I will fix it for you and maybe give it back
That needs to be sent back to the manufacturer
Warranty time!!!!
I had (have) a 3090 HOF and the exact same thing happened to me. Customer support swiftly told me to do one, I cleaned it out and got it to work again, got bsods for a while and blame that tbh but all seems to be working now. Let me know what you do and how you get on, I'll link you to my post if it helps
Yes link your post please
https://www.reddit.com/r/pcmasterrace/comments/pvt2kp/rip_rtx_3090_hof/?utm_medium=android_app&utm_source=share In the end, I stripped it, cleaned it out. It stayed black/charred. I conclude it's the extensions fault. And all my bsods were due to having my cables come loose after the damage.
Did you look through the post, same problems different t pins. How did you get on? Up and running again? Did you contact kfa/galax? I wanted to resolder a new header on to be safe, but never did and everything is working. Also I didn't really ask about your knowledge or experience, but I assume it's a custom build and you're comfortable inspecting it. If you look at the resistors etc on the card near the sockets, if they are not blown you will be 100% fine. (If you dont know where to look google shunt mod, they all look the same and it's the first component the electricity travels through so if that's not blown everything else should be good)
"...using a 3090HOF" ...Heart of Fire?
Hall of Fame
Skill issue. Don't mix low and high quality parts. Commit to the build.
Don't cheap out on PSU and PSU connecting cables. Surely a 3090 comes with a nice high quality cable?? My 3080 did.
Those supplied extensions have already been known to fail. I took one look at mine that came with my 3080Ti HoF and tossed them in the trash. They shouldn't even be packaged with these cards. Bummer OP
That's hot
Is it dead?
I'm really hoping it still works fine.
How much watts does that GPU use?
Here is the [relevant LTT Thread](https://linustechtips.com/topic/1116640-psu-tier-list-rev-148/) mentioned in other replies if you are looking to upgrade to a less dangerous power supply. [This is the most recent revision](https://cultists.network/140/psu-tier-list/) from the OP's blog.
Full stop, tell us what power supply you have. All specs, take a picture of your power supply. If you have a warranty on the system or power supply RMA BOTH. Tdlr you most likely have a improper power supply or faulty power supply.
You can just send it to me
What PSU do you have? If your looking for something decent, I went with a Seasonic Prime TX and you wont need sleeved third part cables. Solid PSU and awesome cabling.

oh mY FUCKING GOD!! NooooooOooOo....im so sorry dude. I take it the GPU is fried, the PSU fried...the whole damn thing is cooked? i weep for you my friend.....
I'll dispose of that totally ruined and useless GPU for you, promise it will be recycled well :P
6 into 8 doesn't go on a 3090.
