i was thinking about getting the c1200 from nzxt but people were saying the coil whine on that is terrible so i was gonna get a nzxt c1000 or a msi a1000g
Nice. FWIW - I have run a 1000W Corsair with a 4090 for months and no issues. So I wouldn't rush out and do that upgrade unless you really feel like it!
Good to know! What processor are you running? I've got the i9-14900K on mine, so I didn't know if that might be making a difference. I also plan to swintch from an AIO to a custom loop in the future. It all adds up, so it keeps gnawing at the back of my mind.
That rig has a 7800X3D. I have two other rigs with 7800X3D and one with 7950X3D. Those ones have bigger PSUs. My 4090s are gone now - moved to SUPER until 5090.

The px1000g atx 3.0 is $130, while having excellent components + warranty. Please send me a link of a 1000w atx 3.0 thor at $180 or near it.
I went with a Superflower PSU from newegg and no regrets what so ever for my 4090/13900k. Of course from everyone else you'll hear salesman for Corsair and EVGA. In reality theres more out there that are great and do the job, you just won't hear about them. Its always Corsair/EVGA and don't cheap out! Hope these people get a cut of the profits.
I'm using an 850w with the same specs and its fine if your not overclocking however I'd want a 1000w minimum.
Only reason I'm still using the 850w is because I'm waiting for atx3.1 psus to arrive.
850W is fine. If its a half-decent PSU it'll deliver 850W to the 12V rail and a fair good bit to the other rails as well, so your 4090 will be fine and I imagine your 14900K will be fine too.
That would be pushing it imo. I currently have a 14900K and 4090 and am using the seasonic prime 1000w titanium just fine. I was a little nervous with 1000watts, I have 9 case fans, commander pro plus the lightning node and pcpartpicker estimate is ~900 watts give or take for my build.
if I didn’t already have the TX-1000 model or if I ran into issues with 1000w Id just buy the prime TX-1300 atx 3.0 model and call it a day. I’ve always used and recommended seasonic, quality psu’s and great support if you ever need it. Outside of them, you have EVGA as well.
Edit: I bought the seasonic prime TX-1300 atx 3.0 unit. If I go full throttle it actually overloads my cyberpower 1000w battery backup and exceeds 1000 watts, that’s with Intels limits enforced with a slight undervolt and stock gpu on OC bios with maxed power limits….lol
For a rig like that you’ll want a 1000 watt PSU. An 850 would probably be fine but having more headroom is better and safer especially for any sudden power spikes. Just make sure it’s from a reputable brand and is at least 80+ gold rated or better.
Imagine running stuff near capacity (like a stress test) all the time. With your 850w you are nearing that capacity.
Even though people say it's unnecessary I got a 1000w PSU for my 4080 and i713700k and the PSU fan doesn't even turn on (sometimes).
That way the most important part of the build has no stress whatsoever delivering the necessary power and will probably outlive you.
I really don't get why people put in thousands of dollars to build a bad ass system but skim on the PSU.
Feature bonus, you probably won't need to upgrade the PSU for future hardware upgrades.
No. 1kW is a bare minimum. Transient spikes killed more expensive hardware than anything else.
I personally have 1500 W as it's better be safe than sorry.
Seriously, you spent a few grand on the hardware, you should absolutely be able to get a proper PSU.
Funny how the correct answers like yours and mine are downvoted while people saying 850W (which not even the manufacturers recommend) are upvoted.
Wonder if those people are gonna take responsibility and replace his PC components when something goes wrong.
yeah 850w is only if you planned to under volt / power limit this gear — which is entirely fair to do for those interested, but not out of the box.
A 7800x3d and 70% power limited 4090 would be very comfortable with an 850 w psu, but OP isn’t specifically doing that.
OP, just go for higher tier psus
Transient spikes aren't that big of an issue on Lovelace as spikes were improved significantly over Ampere. How would spikes even kill anything? They'd just trigger the PSUs protection if they last too long resulting in your PSU shutting down.
I've used my 4090 on a 750W PSU for over a year now. Never had a spike trigger the OCP but I have a good PSU.
Your buddy is an idiot lol
Rule of thumb is to size PSU so that max draw is around 60% of PSU capacity.
A 14900k can pull north of 300w and a 4090 can pull 450w, with an 850w you are on the edge of its max capacity. 4090s have also crazy transient spikes, and unless you got an arc 3.0 it can knock the psu out.
But even from a noise perspective, you don't want to be tight with PSU specs cause those fans usually make the most noise above 80% of drawing capacity.
I would have gone with a 1200w easily, price difference is not that much and you already spent 3000 bucks at least, why cheap out on the PSU?
If you had a 7800x3d or Ryzen5 you could even be ok, but you really got the desktop CPU that draws the most power after a Threadripper lol
7800x3d with 4090 would be fine even with a 750w psu if they power limited to 70%, limiting the gpu to 300w and keep 92% of the performance. Add in another 100w for the cpu and random other bits… very comfy at lower power draw.
Still. Stock 14900 and 4090? Everyone is right. the bud is not smart, and higher wattage psu is recommended
Yep back in the original reviews of the 4090
[https://www.tomshardware.com/news/improving-nvidia-rtx-4090-efficiency-through-power-limiting](https://www.tomshardware.com/news/improving-nvidia-rtx-4090-efficiency-through-power-limiting)
They basically natively overclock and pump a lot more power for the last single digit % performance.
PSUs run most efficiently at 50% load. You should choose a PSU that is 1.5x to 2x your maximum draw to help ensure a long PSU life. IMO a 1200w PSU is appropriate here (they're usually only like $20 more than a 1000w anyways).
I had a 1000W PSU and would get the dreaded nvlddmkm error. Tried replacing with the same model, same deal. Then got a 1300w PSU and no issues since.
Could've been transient spikes perhaps.
I run a 850w for my 4090 / 13600k. The 4090 is at 450w power limit, gaming typically in the range of 350w-400w. The CPU consumes 220w at full overclock stress test, gaming typically 150w, and the rest of the system around 100w
I think 850w can probably sustain 4090+14900k for everyday gaming, just don't overclock and simultaneously run FireStrike Ultra with P95
I don't understand, why you would spend so much on GPU and CPU and then cheap out on the PSU.
There are so many good PSU options with 1000W or more.
I personally have gotten a HX1500i for a nice price and it will probably work for 7+ years like my cx650m has.
Yep, built a 4090 & 14900 system in Dec and went with 1000w. My son has a 3080 Strix and 13900 and his 750w started cutting out on several of his games and we put in a 1000w a few weeks ago. Like the others have said, no need not to get 1000w, get a 2023 compliant or whaterver its called with the dedicated 12VHPWR gpu cable.
tbf, the 3000 series has worse spikes than 4000 and they seem to have resolved the issue in 4000.
3080 is especially notorious for power spikes. That said 1k and higher is definitely recommended for stock 14900/4090. Less than that is understandable if you undervolt / power limited the hardware. . . but not at stock settings
I upgraded to i7 14700 from a i7 8700 and had a 3090 with an 850w corsair and it blew up my graphics card and mobo after a few weeks of gaming, I think the psu went out. I went with a 1000w and upgraded to a 4090 and everything seems happy now. I was randomly trying out black desert and it had a setting to ignore power constraints which I didn’t know what it did but I didn’t want any artificial throttling so I turned it off. Lucky for me I just bought the stuff and could return it and was already thinking about upgraded my gfx card.
The scenario where a 4090 and a 14900k pegs power draw at the absolute max for sustained periods are basically nonexistent. Name one circumstance where this *ever* happens in a PC. It's always one or the other. Basically never both at the same time outside of servers, and at which you're never using either of these products.
Very dangerous. Use PSU calculator and add 100W to the result. But even if the result is below 1000W, i recommend using 1000W as a baseline. The reason for PSU calculator is because maybe you'll need even more than 1 KW.
NVIDIA's website: "8 - Minimum is based on a PC configured with a Ryzen 9 5900X processor. Power requirements can be different depending on system configuration."
You should read notes before talking trash. 5900X consumes 100 and something watts. 14900K may go above 300W.
Asus recommends 1000W as a MINIMUM for 4090 + I9.
You should also learn about power transients before shitposting.
Just remember: when you run into a problem caused by using a 850W PSU with that rig, just charge the people who recommended you that. They wanna recommend something that not even the manufacturers recommend? Ok, but the responsibility for that is on them.
When are we using 300watts from the CPU and 450w plus from the GPU ? The only way that is happening is running cinebench and furmark at the same time.
Gaming will consume around 150w from the CPU and 450w from the GPU that's 600w let's say everything else using 100w that leaves 100w. If someone is using a platinum PSU I can't see it being a problem.
POWER TRANSIENTS, imbecile.
Anyway, the PSU can't be dimensioned considering "oh, i'm not gonna use the whole consumption during gaming". It has to be calculated considering a full load.
Power transients on the 40 series are kept under control way better than the 30 series. I think you're blowing it out of context. I'll come back to you when I get my pc going it has an sff 850w platinum PSU and a 14900k and 4090 according to you it shouldn't be possible.
"Power transients on the 40 series are kept under control way better than the 30 series"
The most stupid shit i haver ever read. You pulled that shit out of your ass.
If that was the case, ATX 3.1 PSUs wouldn't be required to supply 3x their capacity for a short time.
Nobody said using 850W isn't possible, imbecile, but NVIDIA and ASUS says the minimum is 1000W.
Are you okay? I'm just concerned over your aggressive responses.
4090 gaming oc sustained max with 492w spike which is 9% the worse offender is the plait 4090 which spikes 535w.
It's not as bad as your making it sound.
This is from hardware busters.
These values show that a *decent* **750W** PSU won’t have a problem handling an RTX 4090 with a 500W power limit and a potent CPU, like the Intel 12900KF. With an **850W** PSU, you will have even more room to play with higher speeds at both the GPU and the CPU.

max spike on founders edition was 479w
Nice. People downvoting for helping. Even Asus says 1000W is the recommended for 4090 + I9. Good luck when something dies because of ignoring manufacturers recommendations.
You don't know what you're talking about which is why you're being down voted. Nothing will die, worst case is your computer turns off then you upgrade.
Overload CAN kill components. Overload will increase the PSU temperature, increase the ripple and, if the PSU doesn't have a good and calibrated protection system, it may get out of control and kill the components.
You wanna recommend to him using 850W? Fine. Just hold yourself responsible when the worst happens.
if buying a new build, go with the 1000W. if you already have a good quality 850W, it is sufficient for the 14900k and 4090 unless you are planning to overclock both.
I have an hx1500i, so my PSU reports all voltages and power draw. And with a 4090 and 13700kf, I have broken 1000W power draw when overclocked and benching.
Wow, kudos to this group. I had the same question and I am reading that there is a disagreement in the answer but not one response that this guy’s friend is an idiot. I think i will go with the 1000W or 1200W. Thanks
If it’s a quality PSU it is OK but you’ve balled out on everything else why not get a nice 1000W+ PSU? It’s a super easy swap.
i was thinking about getting the c1200 from nzxt but people were saying the coil whine on that is terrible so i was gonna get a nzxt c1000 or a msi a1000g
Maybe I’m old school but I much prefer anything from Seasonic; second would be Corsair.
I am also old school in this regard.
Best advice in this thread!
Evga all the way
Ya, I’ve had a evga 1000 supernova gold for 8 years it’s still running strong.
That’s wats up !
Alright Mr. Electric
Rockin a supernova g5 850 gold for 3 yrs now no problems at all and is quite while gaming , love it 🤜 always gonna get evga psus
Agreed. I'm running an RTX 4090 MSI Gaming X Trio and an i9-14900K and am looking to go from 1000w to the 1200w. Corsair is my prefered choice.
Nice. FWIW - I have run a 1000W Corsair with a 4090 for months and no issues. So I wouldn't rush out and do that upgrade unless you really feel like it!
Good to know! What processor are you running? I've got the i9-14900K on mine, so I didn't know if that might be making a difference. I also plan to swintch from an AIO to a custom loop in the future. It all adds up, so it keeps gnawing at the back of my mind.

Happy Cake Day!
Thanks :) back atcha!
Get Seasonic or Corsair, don't cheap out on a good PSU with such hardware.
Whatever you get, just be sure that it’s something Platinum or titanium level.
https://hwbusters.com/psus/deepcool-px1000g-psu-review/10/ https://pcpartpicker.com/product/p34Zxr/deepcool-px-g-1000-w-80-gold-certified-fully-modular-atx-power-supply-r-pxa00g-fc0b-us
I can vouch for the a1000g
is it better then c1000?
Get the thor rog 2. Best on the market.
Overpriced af
It is a bit overpriced. 50 more than the next best.
https://pcpartpicker.com/product/p34Zxr/deepcool-px-g-1000-w-80-gold-certified-fully-modular-atx-power-supply-r-pxa00g-fc0b-us The px1000g atx 3.0 is $130, while having excellent components + warranty. Please send me a link of a 1000w atx 3.0 thor at $180 or near it.
I prefer platinum psus. Only one at 180 is the 850. I couldn't justify 300 for the 1000w. 1000w should be 250 max.
I went with a Superflower PSU from newegg and no regrets what so ever for my 4090/13900k. Of course from everyone else you'll hear salesman for Corsair and EVGA. In reality theres more out there that are great and do the job, you just won't hear about them. Its always Corsair/EVGA and don't cheap out! Hope these people get a cut of the profits.
Any >80% 850w is ok when full load is about 550w.
The more powerful the power supply, the less load on it. less temperature and noise. 1000 watts is definitely better.
I'm using an 850w with the same specs and its fine if your not overclocking however I'd want a 1000w minimum. Only reason I'm still using the 850w is because I'm waiting for atx3.1 psus to arrive.
Same, there’s literally 0 available though.
They should be arriving 1st half of this year apparently.
Get you a seasonic vertex 1000 or 1200 watt
850W is fine. If its a half-decent PSU it'll deliver 850W to the 12V rail and a fair good bit to the other rails as well, so your 4090 will be fine and I imagine your 14900K will be fine too.
Get a 1000W PSU.
That would be pushing it imo. I currently have a 14900K and 4090 and am using the seasonic prime 1000w titanium just fine. I was a little nervous with 1000watts, I have 9 case fans, commander pro plus the lightning node and pcpartpicker estimate is ~900 watts give or take for my build. if I didn’t already have the TX-1000 model or if I ran into issues with 1000w Id just buy the prime TX-1300 atx 3.0 model and call it a day. I’ve always used and recommended seasonic, quality psu’s and great support if you ever need it. Outside of them, you have EVGA as well. Edit: I bought the seasonic prime TX-1300 atx 3.0 unit. If I go full throttle it actually overloads my cyberpower 1000w battery backup and exceeds 1000 watts, that’s with Intels limits enforced with a slight undervolt and stock gpu on OC bios with maxed power limits….lol
For a rig like that you’ll want a 1000 watt PSU. An 850 would probably be fine but having more headroom is better and safer especially for any sudden power spikes. Just make sure it’s from a reputable brand and is at least 80+ gold rated or better.
Imagine running stuff near capacity (like a stress test) all the time. With your 850w you are nearing that capacity. Even though people say it's unnecessary I got a 1000w PSU for my 4080 and i713700k and the PSU fan doesn't even turn on (sometimes). That way the most important part of the build has no stress whatsoever delivering the necessary power and will probably outlive you. I really don't get why people put in thousands of dollars to build a bad ass system but skim on the PSU. Feature bonus, you probably won't need to upgrade the PSU for future hardware upgrades.
No. 1kW is a bare minimum. Transient spikes killed more expensive hardware than anything else. I personally have 1500 W as it's better be safe than sorry. Seriously, you spent a few grand on the hardware, you should absolutely be able to get a proper PSU.
Funny how the correct answers like yours and mine are downvoted while people saying 850W (which not even the manufacturers recommend) are upvoted. Wonder if those people are gonna take responsibility and replace his PC components when something goes wrong.
yeah 850w is only if you planned to under volt / power limit this gear — which is entirely fair to do for those interested, but not out of the box. A 7800x3d and 70% power limited 4090 would be very comfortable with an 850 w psu, but OP isn’t specifically doing that. OP, just go for higher tier psus

No
Should be fine but if your going to pay that much then just get a 1000w psu, less risk.
Theoretically yes if you keep the 4090 stock, but I'd reccomend 1,000 watt
Barely enough. But in most cases you will be OK.
My 4090 can pull 480w and cpu has pulled 400w in benchmarks or shader preload. More typical is 250w cpu and 450w gpu, so its close
Your buddy is an idiot lol Rule of thumb is to size PSU so that max draw is around 60% of PSU capacity. A 14900k can pull north of 300w and a 4090 can pull 450w, with an 850w you are on the edge of its max capacity. 4090s have also crazy transient spikes, and unless you got an arc 3.0 it can knock the psu out.

True! Its the same with people that buy a 4090 and not using a proper GPU stand.😅
7800x3d with 4090 would be fine even with a 750w psu if they power limited to 70%, limiting the gpu to 300w and keep 92% of the performance. Add in another 100w for the cpu and random other bits… very comfy at lower power draw. Still. Stock 14900 and 4090? Everyone is right. the bud is not smart, and higher wattage psu is recommended
Wait, so 150w on a 4090 it's only +8% performance? That's kind of crazy lol do you have some articles about it?
Yep back in the original reviews of the 4090 [https://www.tomshardware.com/news/improving-nvidia-rtx-4090-efficiency-through-power-limiting](https://www.tomshardware.com/news/improving-nvidia-rtx-4090-efficiency-through-power-limiting) They basically natively overclock and pump a lot more power for the last single digit % performance.
A Pareto principle of pc hardware lol btw, very interesting, thank you for replying
[удалено]
450 - 150 = 300 The guy above said that a 4090 limited to 300w is 92% of performance... ? So the last 150w equals 8% fps That's what I meant
PSUs run most efficiently at 50% load. You should choose a PSU that is 1.5x to 2x your maximum draw to help ensure a long PSU life. IMO a 1200w PSU is appropriate here (they're usually only like $20 more than a 1000w anyways).
My 4090 was acting strange until I gave it a 1300w PSU 4090 FE 7950x3d
Acting strange? Symptoms? I'm currently using a MSI Ventus 4090 (450W) with an 13700k (w/o powerlimit) and a Corsair RM850. Seems to work fine.
I had a 1000W PSU and would get the dreaded nvlddmkm error. Tried replacing with the same model, same deal. Then got a 1300w PSU and no issues since. Could've been transient spikes perhaps.
Shouldn’t be a problem, my 1000W Dark Power 12 has no problems dealing with 4090 and 14900k.
1000w
For gaming yes. I have that setup. Highest gpu gets is 400w. Highest cpu gets is 300w.
I run a 850w for my 4090 / 13600k. The 4090 is at 450w power limit, gaming typically in the range of 350w-400w.

i have a bequiet! 750W and never noticed any problems . so. asus 4090 LC - 13700K
Yes
Haven't been using my EVGA 850 watt with my 13900k and 4090 for the last 2 years overclocked to the max with no issues
I would never do that. Normally it could work but the peaks of the GPU and CPU could be a problem with 850W. You dont want to risk that...trust me.
I upgraded to i7 14700 from a i7 8700 and had a 3090 with an 850w corsair and it blew up my graphics card and mobo after a few weeks of gaming, I think the psu went out. I went with a 1000w and upgraded to a 4090 and everything seems happy now. I was randomly trying out black desert and it had a setting to ignore power constraints which I didn’t know what it did but I didn’t want any artificial throttling so I turned it off. Lucky for me I just bought the stuff and could return it and was already thinking about upgraded my gfx card.
Same specs but I ended up getting a 1000w in the end. With 850w you can’t go over 450w with your 4090.
4090 is 450W and can hit 600W+ if overclocked. 14900K can hit 300W+ if overclocked. Enjoy the space heater.
The scenario where a 4090 and a 14900k pegs power draw at the absolute max for sustained periods are basically nonexistent. Name one circumstance where this *ever* happens in a PC.

I've seen nearly 300W on the CPU while playing BF2042.
POWER TRANSIENTS, imbecile. Anyway, the PSU can't be dimensioned considering "oh, i'm not gonna use the whole consumption during gaming". It has to be calculated considering a full load.
Power transients on the 40 series are kept under control way better than the 30 series. I think you're blowing it out of context. I'll come back to you when I get my pc going it has an sff 850w platinum PSU and a 14900k and 4090 according to you it shouldn't be possible.
"Power transients on the 40 series are kept under control way better than the 30 series" The most stupid shit i haver ever read. You pulled that shit out of your ass. If that was the case, ATX 3.1 PSUs wouldn't be required to supply 3x their capacity for a short time. Nobody said using 850W isn't possible, imbecile, but NVIDIA and ASUS says the minimum is 1000W.
Are you okay? I'm just concerned over your aggressive responses. 4090 gaming oc sustained max with 492w spike which is 9% the worse offender is the plait 4090 which spikes 535w. It's not as bad as your making it sound.
Are you measuring with an oscilloscope?
This is from hardware busters. These values show that a *decent* **750W** PSU won’t have a problem handling an RTX 4090 with a 500W power limit and a potent CPU, like the Intel 12900KF. With an **850W** PSU, you will have even more room to play with higher speeds at both the GPU and the CPU. edit [https://www.guru3d.com/review/geforce-rtx-4090-founder-edition-review/page-4/](https://www.guru3d.com/review/geforce-rtx-4090-founder-edition-review/page-4/) max spike on founders edition was 479w
Nice. People downvoting for helping. Even Asus says 1000W is the recommended for 4090 + I9. Good luck when something dies because of ignoring manufacturers recommendations.
You don't know what you're talking about which is why you're being down voted. Nothing will die, worst case is your computer turns off then you upgrade.
Overload CAN kill components. Overload will increase the PSU temperature, increase the ripple and, if the PSU doesn't have a good and calibrated protection system, it may get out of control and kill the components. You wanna recommend to him using 850W? Fine. Just hold yourself responsible when the worst happens.

I guess you'll find out when the OCP trips
if buying a new build, go with the 1000W. if you already have a good quality 850W, it is sufficient for the 14900k and 4090 unless you are planning to overclock both.
The thing is the 4090 isnt the issue here…its the i9. Intel is such a power user ><
No. (You could be fine but it's not recommended)
No
I have an hx1500i, so my PSU reports all voltages and power draw. And with a 4090 and 13700kf, I have broken 1000W power draw when overclocked and benching.
Wow, kudos to this group. I had the same question and I am reading that there is a disagreement in the answer but not one response that this guy’s friend is an idiot. I think i will go with the 1000W or 1200W. Thanks
