***** AMD RX 7900 SERIES AVAILABLE & IN STOCK TODAY FROM 2PM ****(BACK ORDER UPDATES WITHIN THIS THREAD)*

Yep exact same issue.

I'll say see a flick of game load and whole rig power down. For example tried Wolfenstein - The New Colosus this morning, all the way upto actual game load I have system running. Then power down. Witcher 3 does same, only managed a few 3DM FS bench, but 99% any 3DM bench/test rig turn off.

Only way card ran was with down clock. Voltage control not working on either driver for me.

Tried DDU, fresh W10 and W11, same issue at stock. Only resolve down clock GPU.

I used separate power cables for each plug. Also have watt meter. Things that ran at stock I was getting correct power usage.
Which PSU are you using?

PSU not issue. I have a wattmeter and in past Threadripper with RX Vega 64 used as well on same PSU and seen higher power draw then correct HW in use.

Cooler Master V850, Seasonic platform, single 12V with 70A. Used stock cables, separate cables each plug on GPU. The PSU is 850W rated DC side, so more than ample.

VRM has also been different on Nitro as well. Need to see a tear down of them to know the differences.

Did say that in past post in this thread.

But so far all RX 7900 XTX PCB use same VRM controller/Mosfet and only choke differs.

Sorry for double posts. On mobile device and not seeming to work for grabbing quotes and placing in another post.

There's a real chance you are falling into a transient power spike issue. It's a big part of the updated 3.0 PSU specs to allow overcurrent upto 140% for parts of a second and not switch off.

My PSU has no OCP :)

All protection features but OCP (Over Current Protection), which is meaningless in a single rail, 850 W unit, are present.

Would show you Jonnyguru review of it which states same, but no longer online anymore :/

Sorry I'm confused on what you are getting at.

All of those protections I don't think are kicking in. Besides I have used card at stock using compute loads for over 1hr pulling ~475W AC side, so DC way lower.

Card has issue on 3D loads. As said some 3D loads do work at stock. And when I look at HWINFO (latest) and wattmeter I have correct high draw.
 
It's an old PSU now ? If system is just shutting off rather than rebooting that would point to a power issue which could be the PSU or the power delivery hardware on the card. Some old Seasonic based PSUs had issues with transients on more recent GPUs but I couldn't see anything to highlight whether this one would be affected or not.

Give this a watch, very good video from Steve, explains things very well. It might not be your issue but with just 850w it's very possible.

I did, thank you :) .

Currently I don't suspect PSU. As said I have used in past very high draw parts with it.

PSU is cleaned internally using air every 3 months. My rig gets air dusted every couple of months.

Known good rig went wacky with new GPU.

Here's another member on OCUK, same issue and same way they resolve if you read on.

Also see this, HW editor try XT as well as XTX


Originally I thought driver, I have tried 2 now. Plus my card voltage control doesn't work, both drivers, both OS, was trying UV, I always just have stock voltage.

I had the same thing when switching to ryzan 5950x i had a 8pack 2000W psu so no problem with power i thought, but every now and then it would crash,just switch off, tried so many bios's and fix's but never doubted the PSU. I then read about power hold up time and the superflower 2000w psu had poor hold up time.
I switched the PSU to a 1200w corsair and not one more crash. hold up time was much better on the corsair PSU. I wasted months, even changed board and CPU to another 5950x and the PSU cured all. it has never crashed since. Even though the superflower had 2000w it still crashed, but it never did when i ran intel before that.
Power spikes can be a pain in the rear, and like myself i thought a 2000w PSU was not the issue.

I had an issue with voltage not working, turns out MSI Afterburner had auto erase setting sticker on startup and I didn’t realise. :o
 
Look in windows event viewer, it will tell you why it shuts off. mine used to say power. to just shut off is a power issue.
Did check event viewer and yes it is system shutdown power event, but you can get that even if not PSU related.

But as stated this PSU has no OCP. It can take 70A on 12V, reviews show that on that rail.

Not using AB or anything other thing than Wattman when I say checked at stock. Not even installed.

Clean OS W10/W11 with bare minimum to test at stock CPU/RAM, stock GPU.

Trust me, last thing I wished to do was RMA.

Getting Pulse as I had faulty MBA. If Pulse was not available to pre-order I'd have MBA again. I don't need 3x8pin for UV. I don't need dual bios as SW will allow what I want. But as the opportunity is there I am taking it.

Several days ago on OCN I stated MBA has more than enough performance for my daily uses. And I said I never went AIB at launch as wasn't gonna pay extra for OC ability. The Pulse is max I would pay for AIB. Paying extra £250 vs MBA for Nitro/TUF, etc for card I gonna take the cooler off and never use extra power limit would be a nonsense to me.
