How much power does the 6900xt need ?

[Aquinus]

Today, just try the card with your current PSU, run some benchmarks. If it's stable, you're good. if you experience instability or shutdowns, the GPU needs more juice. It's that simple.

I'm still traumatized by seeing PSUs destroy hardware and the 6900 XT is a very expensive piece of hardware to take that kind of gamble with. The OP asked our opinion, but if he's come in with his mind already made up, then there is no point in this discussion. I'm not here to give people validation, just my 2¢.

Well, he has an EVGA Gold, it should have all the right protections in place. That's why I said I would have tried this some time ago.

I'm just thinking about my machine and how much the Vega 64 can draw and the 6900 XT is going to draw more. Depending on how power hungry the rest of the system is, he might be right at the limit. If I dropped a 6900 XT in my 3930k machine, I wouldn't be surprised to see 900w+ off the wall with the machine running full tilt, overclocked and all.

Either way, why invest in good hardware if you're going to leave a weak link?

Not sure, Vega 64 were crazy power hungry and could hit some insane spikes 700w+ without undervolting and tweaking iirc ,350w peak gaming consumption on a 6900xt for comparison, I think the OP's original PSU was fine wouldn't call it a weak link by any stretch, though with the 1kw Corsair he has bought he will be more than just fine

Your approaching the problem wrong. If you're spending enough to get a 6900 XT, you shouldn't skimp on the hardware that could kill the card if you push it too hard. Do yourself a favor and put just as much TLC into your PSU choice as your GPU choice. If I was getting a 6900 XT, I would be buying a 1kW PSU that's 80+ Gold or better. In fact, my Vega 64 and 3930k use a 1kW 80+ Platinum and after a decade, the PSU is still running strong even when I push the machine to its limits.

To add to your sentiment I have a HX1200I that I bought 8 years ago that is still the base of my system. Even works in HWinfo64

which pci-e extension cables will work with the Corsair CP-9020094-UK RM1000x 1000 W please ? , the pci-e cables are stiff as hell and have an extra connection on each cable making it look ugly/untidy (a noob to the extension cables lol)

Do you mean the main modular cables of the PSU, or extension cables to make the connection longer? Standard extension cables should work with any PSU, but the modular cables I think you'd have to buy/obtain them from Corsair because modular cables are not interchangeable with other models/brands of PSU.

Then since what they connect to standardised you should be fine with anything that is intended for generic PSUs. In my country they're almost all silverstone and they say on their website (for the ones that I googled) that they are compatible with all PSUs.

Personally, I'd avoid unbranded ones from ebay and the like.

^THAT^ esp being new.
i would suggest - for an example - just a quick google for your side of the pond:

why not all the them?



however i do avoid extensions generally - but CableMod is a go to brand for (alot) folks (i know) who build boutique rigs.

I'm running a Nitro+ RX 6900 XT with a Corsair HX1000 Platinum and it's fine, that 1kW Corsair RM1000x should be able to handle that beast.

"Recommend" doesn't mean much because you can have really cheap power supplies that can't deliver its rated power in the first place. So I recommend going by the max power draw that card can do. It will be limited by AMD drivers because either you reach the Power Limit or voltage limit. It will end up around 350 Watts. 400 watts if you want to be safe.

I'm running a Sapphire RX 6900 XT Nitro+ SE togheter with an Intel i9-12900F and a Corsair RM850 Plus Gold (2021). Never had a problem, not even during extensive stress tests with the GPU overclocked and the CPU with no PL limits.

My 6900xt Reference runs on a 850 Seasonic and is happy.

same here


I do have one exception going on. Hitman 3 def is making this GPU, which is new to me in the last few weeks, spike in power. I do not overclock the GPU but when I run Hitman 3 there is a chance it makes my PC crash where upon restart you get that AMD Radeon message stating "Default Radeon WattMan Settings Have been Restored due to Unexpected System Failure" normally indicating poor OC or UV settings.....but I was using default settings already. I've never seen this message except when I was doing custom settings, so I knew I was the problem and would change settings accordingly to get stable performance. So the only explanation I can think of here is there is a severe power spike going on. This GPU default PPT is ~255W under default settings. The most I've seen HWInfo list power draw at was 257W which is totally fine and within range of my system capabilities. So there must be a big 'ol spike happening during heavy load scenes for this game. I really should turn on my 2nd display, put HWInfo up over there, and see if it lists this power spike when this crash happens....bc I cannot check the HWInfo window when it's on the same display as the game once the PC freezes up and automatically restarts when this happens.

this only happens with Hitman 3, and I can power limit and limit the clock and it happened much less frequent to point I thought I was in the clear after a couple plays, but it still happened eventually. Game still runs well at 4K full blast max settings, but I have to reduce to 1440p to stop this from occurring, thought I was in the clear, but it even happened once on 1440p! Only once, but still....

So I'd say 850W is bare min, which is most of the review worlds general consensus, but 1000W+ is the true "safe zone" from consumers/users feedback

thanks for the link

My XFX has a light overclock and I'm running fine on a good quality 850W power supply. Good enough for the moment.
