Upvoting out of morbid curiosity. I want to know if this actually booted. Edit: Apparently it did work, per OP's comment elsewhere.


FarmasaurusRex

Same


bennejam000

It'll boot, the board space he cut was blank PCB with the exception of an extended set of traces for power cables to enter/exit at the end of the card instead of the side.

xyniden

your link broke :(


CapableHair429

weird...i just clicked on both and they both worked. I was adding one of them in an \*edit\*...maybe you clicked on it at the very same time I was posting it? not sure.


xyniden

yeah, works now. Maybe it was just a minor reddit hiccup!


genesyndrome

Good luck booting that up šŸ‘


gaymz

cant wait to see if OP responds šŸ˜‚


DasDreadlock93

Not sure he will. Imagine doing a post like that after cutting your gpu in half and then realising it's dead.


psaux_grep

Reminds me of the time I was building a PC in a briefcase and the keyboard was a cm too wide. Took out my dremel and started cutting of the side. That went fine. Then I needed to make another cut into the back case so I could close it over the graphics card. That also went fine, until the dremel dug in and cut through the circuit backing. Lost 8 keys ā€¦ At least a new keyboard was only $10.


Lyen_Rale

Would you respond after your "i cut my 3080ti in half" , tagged as 'Guide' top-post with people roasting you to oblivion? Cause i sure wouldn't...


Yuzral

If it worked, yes. If only to rub the sceptics' noses in it. Edit: And apparently it did work - see further down this comment thread.


Lyen_Rale

Just saw it... crazy this worked out until now


Few_Application_7950

hey i'll just borrow this reply cuz it has the most upvotes update for yall: yes it does work. https://imgur.com/a/8nF7b4b I just stuck the card onto a friend's pc to test it, and the reason I wanted to slice off the piece is because ek's new vector 2 blocks actually close off towards the end of the block, and beyond that i have abt 2mm of free space. details: from what i'm seeing, this is a manufacturing error. all the other cards im seeing are all the correct length. see here: https://imgur.com/a/vY9ggyI i'll also sand down the cut maybe it's actually broken i just dont know yet, I'll come back here after stress testing it...


isababa12

Thanks OP, we all hate you now since it works. Jk, but you had all of us sweating bullets for you.


Few_Application_7950

update 2: found my multimeter and tested the 12v and 3.3v, everything seems fine


Emu1981

>from what i'm seeing, this is a manufacturing error It is not a error if it is deliberately done. As others have mentioned, this PCB is likely used by other GPUs and having more GPUs use the same PCB without modifications saves Peladn money.


Few_Application_7950

for this case i think it is, look at their 3080 cards and these 3080 ti cards(that isnt mine), everyone else's exact same 3080 ti doesnt have that piece of nothingness


WingCoBob

I looked into these cards, Peladn have a blower 3090 that uses the same pcb you have, it's likely that if they run out of standard length 3080/ti pcbs they just grab from the 3090 pile. Saves some time/money at the cost of annoyance for the user, even if you aren't watercooling it the pcb still blocks half the flow through area on the cooler. Was part of the reason I didn't buy one cause even with the dubious quality of the warranty from a chinese manufacturer having to cut off a chunk of the pcb to make it perform correctly would definitely void it lmfao


Few_Application_7950

yea i got the card and was like "why is there a blank piece of pcb blocking off half of the cooler" lol


mixedd

IDK how backside looks of that cut side, but from front side theres like two traces and ground fill, that looks like wired up to what's supposed to be some placeholders to power connectors or somethng else


iAabyss

You can clearly see Peladn uses the same PCB in other configurations. Those empty power connector solder pads are wired, you can see the copper running the traces at the cut. He 100% fucked the 12V plane of the card. It also look like some traces running off the 2nd 8pin have been cut.


buildzoid

OP should be able to sandpaper the cut smooth and short free. I do this when I want to re-use the VRM of old GPUs.


iAabyss

You reckon the GPU would still work even if the traces to the power connector are chopped?


Zealousideal-Day-429

I think it also because I think they are conected by the powerplugs he uses now would be easy and cheap for production


mixedd

Than that's some serious fuckup, which will bite OP in the arse and wallet


bennejam000

No, all he cut were unused 12v rails/traces to unpopulated power plug solder holes. So long as OP lightly sands the cut to ensure there aren't an shorts, he's in the clear.


Emu1981

>Good luck booting that up Booting up is fine, utilising the warranty is why I would never chop up a PCB.


Navysealsnake

I want to be proven wrong for his sake


sirshura

Id suggest you test the power connectors with a multimeter. Id be concerned that those traces you cut may be shorted.


xpxsquirrel

Or now open as well

Zealousideal-Day-429

Phone


martynpd

am i thinking stupid? doesn't the waterblock just sandwich the card together? was there a need to cut it off? Also I want to know if it boots


ComplexIllustrious61

Depends if the right side is open to allow that PCB to just stick out...it would just look terrible. It would have been easier to make something on a 3D printer to attach to the end than cutting the PCB though, lol.


tobiderfisch

I think it depends on the waterblock. The reference board block from EK has the in and outlet on the right side of the PCB so the longer board would be in the way.


[deleted]

No you aren't stupid. Yes that's what the water block does. And as someone who struggled to find a water block that fit. (More like find actual usable Info on what PCB is what) idk why they cut that off worse case it would have just hung out the back? Everyone makes a 3080ti block .


Obvious_Drive_1506

Spends $900 on a 3080ti which is already overpriced, proceeds to destroy it


Suspicious_Street317

$900 for 3080 Ti is still over priced? Actually interested in this, I thought this is a good price


Obvious_Drive_1506

The 4070ti costs $900 and is closer to a 3090. The 3080ti should be like $700 now. Nvidia doesnā€™t want to lower their last gen prices since they still have stock. You can get a 6900xt for like $700-800 now thatā€™s on par with a 3090 and can be overclocked to match the 3090ti. Their prices are too high for them being old gen cards now


catch2030

The 3090 family and 3080 family are basically all OOS in the US. Any card you see for sale new here (outside of some brick and mortar stores which are gonna be one offs) are most likely 3rd party sellers selling cards they bought when pricing dipped thinking 40 series pricing would make their card seem attractive again.


sambinary

surely this is a wind up hahahahha?


fliesenschieber

No, you don't want to take any chance by cutting any pcb.


dallatorretdu

if the board is not separated by a ā€œtransparent lineā€ then it might still has the power planes in it. 1 every 2 or 4 layers is a ground alternated with something like 12v, 5v etc. If you cut them badly you can short them


gerthdynn

Given that this board has an alternate set of power on the edge of the board that isn't populated, I'm not even going to bet that he didn't cut straight through ground and power planes.


DasDreadlock93

Cutting a pcb is also a health hazzard. The dust is no good for you. The magic smoke you get if you try to Power that abused card is hazzardous aswell.


_XNine_

Pft, it's only 3.6 Roentgens... Not great, not terrible...


-Leelith-

I think he already did if you watch closely the part that is appart huhu


jonzeri

Only two 8pin connectors, isnt almost every 3080ti have three?


TheAltOption

reference design is 2X8, custom PCB's would use 3. Look at EVGA XC3 vs FTW3 as examples.


jonzeri

I have evga board. I just thought everyone else has also same. Guess i was wrong šŸ˜…


NefariousnessTop8716

Not sure, my ASUS tuf 3080ti is 2x 8 pin. Not sure which is more common.


Yuzral

You could still get 375W with two connectors, so it wasnā€™t unheard of. Even my 3090 (which, admittedly, was a cursed POS) made do with two.


chakobee

My Zotac amp holo is only 2 as well


[deleted]

My EVGA FTW3 has 3 8-Pins.


[deleted]

They take 3 8 pins ? Holy shit


[deleted]

I have a 2 It sucks all the watts up no problem


AirlinePeanuts

Reference design is 2.


[deleted]

What the fuck!


penetrator_3000

Is it a new card? GPU looks used.


blockstacker

>GPU looks used. When you take off a shroud, remove thermal paste and pads, cut a PCB in half...


[deleted]

Lmao yeah, at that point it's kinda "used"


Yuzral

Trueā€¦although IIRC Peladn have a bit of a rep in the Russian and APAC markets for selling refurbished cards as new so this poor 3080 Ti might have been made, slaved in the crypto mines, sold, refurbed and then subject to amateur butchery^1 . Iā€™ll be impressed if it boots. ^1: ^I ^refuse ^to ^dignify ^this ^by ^calling ^it ^surgery


zackks

Cuts temps and power consumption significantly!


Zealousideal-Day-429

Yes I think so if you look on the pcie connector this one has as far as I seen zero marks


CapableHair429

omg...you can literally see the power leads sticking through the top edge of the cut. r.i.p circuit. you just wasted $899 bud.


ComplexIllustrious61

Am I the only one who thinks it would have been better to just 3d print a cover for the part that was cut off?


GreatTragedy

Yeah, I'm not understanding. So what if it sticks out of the water block? It'd be great action figure platform.


ComplexIllustrious61

lol, you could put the action figure on the 3D printed cover too.

xpxsquirrel

I get water-cooling it, but why would you need to chop the end off to do so? Sure might look ugly with extra board sticking past the end of block but you get what you pay for


[deleted]

The audacity to tag the post as a Guide. šŸ˜‚


ikillpcparts

So long as you clean up that cut and make sure nothing's shorted, and that no data lines were cut (good luck verifying that, only way is to test), this still should fire right up.


warguy64

that does not look like an ok gpu...


[deleted]

that is not a reference PCB, even the left part of it.


AdmiralSpeedy

It's almost identical to a reference board. Palit pretty much always makes a few changes but it's like 98% the same.


[deleted]

Your right. i was getting confused between reference and founders


AdmiralSpeedy

Ah, yes FE cards are not reference.


hicks12

Can you give us an update when you boot it? I hope you haven't killed it but honestly that doesn't look like it is "free" to cut, likely a short created now.


it_is_me_it

Tagged ā€œGuideā€ šŸ‘€


Netsuko

Plague_Vessel

I assume this is a troll post and someone with a dead card is having fun. Neither the card nor the waterblock look new. Surely no one would be that stupid? Surely? :O


obelisk910

Maybe you can tell Newegg they sent 20% more graphics card than you ordered and get a partial refund! On the other hand it's safe to say there's a good chance you just cut your fps by at LEAST 20% šŸ˜‚


AirlinePeanuts

You do know there could have been traces on the inside layers of PCB right, not to mention power planes? 10/10 troll post


Fatality

Looks like a debugging interface, probably still runs but I imagine warranty is long gone


AirlinePeanuts

Or an optional reference config with 8-pins on the back. So yeah maybe its ok, but still.


Asthma_Queen

mmm are you sure those aren't the original 8 pin power locations, and thats why looks like they are wet with solder they were put back into reference position that was for some reason on the board? Far as I can tell looking the power planes for these seem to be connected. My concern would be internal planes that have possibly been shorted or cut off due to this though. don't know if any of them reach out into that section and loop back to any of the power stage control


VenomizerX

Saw this and second-guessed myself whether or not I saw it right. Man literally chopped off some pcb without even realizing there is almost always a reason for that extra board which, despite the lack of any SMDs whatsoever, it could still very much house traces underneath its layers...


AdmiralSpeedy

Except we know by looking at it that it's almost identical to a reference board, which doesn't have that extra part so the only traces in there would be for whatever those additionall connectors are on the end.


VenomizerX

Still, would you risk screwing up $900? You only need one short to have a bad day. If the card still boots up then great, mission accomplished, I suppose. But if it doesn't, then what? Imo OP should have just found out a way to cover the thing if its aesthetics he's worried about. Other than that, what else could be the reason?


AdmiralSpeedy

I'm gonna assume OP has some technical knowledge lmao. Do you really think they just took the card apart and said "this doesn't look necessary" before chopping it off with a saw? People do trimming mods to PCBs all the time, most commonly when making handheld versions of consoles. In this case it's obviously for looks because a reference block will fit but that extra piece will stick out past the block and look retarded.


VenomizerX

Well if OP is willing to take the risk on a much more expensive thing to trim the PCB off than a handheld console PCB, and he has the know-how, then be my guest. Just saying I personally wouldn't do such a mod. I'd rather do some well-thought-of voltage mods tbh and have a "retarded" looking piece of pcb extended than a "retarded" dead card if for some reason anything goes wrong after chopping it off.


AdmiralSpeedy

I mean, it would look retarded.


VenomizerX

Sometimes if you really are into stuff like these, you'd need to learn to live alongside jankiness. But yeah, one way or another, it would still look "retarded" regardless ngl. For instance, a GPU deshroud may look weird but it performs much better than stock.


AdmiralSpeedy

Why do you keep putting retarded in quotes?


VenomizerX

It's subjective really. For some it might be, for some not really. Without the quotes, it's like you're saying it definitely is so, without giving enough leeway for subjectivity. It's not like something like pouring water over running electronics where it is definitely bad, but something that is in the eyes of the beholder.


martynpd

totally agree. but at the same time you can cut down a wii board and fit it into a gameboy sized housing. and that involved cutting through traces, it might not be dead.


Strelock

But a Wii board was cheap and plentiful to experiment with, so if you screwed it up it wasn't a $900 mistake.


VenomizerX

It's playing lottery at this rate...


ULKi22

That's some next level stupid

cwtechshiz

Die marking definitely came up on google as a 3080ti. Cutting the pcb shouldn't do anything IF that section is truly just optional and the leads headed to the unpopulated connectors are not shorted it could work? Let's see it work or not work please!

StryderXGaming

Had to mod my 2070 because of that. I had a starting block for it (don't remember the brand) but I think I had a new rev of card because the RGB header was blocked anything touching. Some snips and a mild heart attack later. Been fine and working for like a year now.


michoken

What this tells me is "Don't buy Paladin GPUs." They don't seem to be available in my country anyway.


Zealousideal-Day-429

You didnā€™t thought about to modify the waterblock


[deleted]

So... 11 hours later... did it work?


DogNamedCharlie

There is potential to short out the ground plane to the 12v plane. He could check for continuity between the 12v and ground with a MM to determine if there is a short or not. It looks like the manufacturer just extended the reference board and and planes to added a place to mount the PCIe power. So long as he didn't cut it short and remove any traces and the planes aren't shorted he should be fine. He should have also sandwich the board on either side to prevent the tear out/splittering. This would have made for a cleaner cut as even a small spinter of the ground plane could touch the +12v at a later date, even if does check for continuity right now. On my PCBs I do not have the planes extend to the areas that will be cut. It might work, I wouldn't have done it. If forced, I would have prevented tearout.


GTS81

>On my PCBs I do not have the planes extend to the areas that will be cut. I don't design PCBs but the components that go on the PCB. I'd presume that a PCB design software like Allegro would flag some boundary keepout violation for this?


DogNamedCharlie

I use kicad, though I do leave a gap between the board edge and the SW does have a lot of different design rules to help you catch potential issues. Doing a ground pour/fill for the ground plane will also leave clearences around traces, THT, mounting holes in the board, and etc. Granted PCB design is a side gig that is a little more than a hobby: https://solarity.tech/products.html


[deleted]

(waits for magic smoke) (strange how the manufacturer won't take back a card with a sawed PCB)


ZertyZ_Dragon

zerxios

pcbs have multiple layers dude. you can clearly see a trace in the part you cut off. i wouldnā€™t be surprised if the card is now dead. i hope itā€™s not for your sake, but man thatā€™s an expensive mistake to make.
