PC shuts down with 3090 Rog Strix

[Bman_7]

Hey guys,  

 

I have just gotten a 3090 a couple of days ago. Of course I ran through many GPU intensive tests and had no issues at all. I also played a couple of games and had no issues when playing. 
 

The next day I get on to game and my PC completely crashes and shutdowns. It is a very weird shutdown, it has a really loud click and it completely turns off. It sounds as if someone powered it off. I checked all the wires and connections and tried again and it still crashed. 
 

I proceeded by gathering temperature data and usage while playing and nothing was acting funny, temperatures were normal and usage was fine, but it still crashed. The PSU I got is a few months old and never gave me any issues, but that’s my most expected culprit. It might also be the RAM. 
 

I am all out of options and would really love some help. Please and thank you.

 

PC:

 

CPU: AMD 3900x

GPU: 3090 Rog Strix

MOBO: x570 Ultra

RAM: 32 GB 3200MHz G. skill Trident

PSU: 850W Gold 

 

I was also not getting expected frames with the 3090 but I’m pretty sure it’s due to the CPU and RAM bottleneck, hope to upgrade soon after I figure out this issue. 
 

thanks again.

What's your exact PSU model? "850W Gold" doesn't tell us a lot.

EVGA SuperNOVA 850 GA, 80 Plus Gold 850W, Fully Modular

Sorry man I thought it didn’t matter. EVGA SuperNOVA 850 GA, 80 Plus Gold 850W, Fully Modular.

When the PC shuts down, does it crash or just shut off?
Also, how do you have your 3090 hooked up? Are you using individual cables or daisy-chains?

So it literally shuts off. No blue screen, no desktop, just off. The only thing that stays on is the RGB on my RAM sticks. I have a daisy chain for two and then a single cable. I used GPU-Z to see the power on each cable. It was pretty evenly distributed, about 100-120W coming out of each. And prior to the shutdown those values aren’t being skewed or anything.

Use dedicated cables for all three.
Here's a quick diagram:

Spoiler

Each 8-pin is rated for 150W of power. This goes for its cable as well, so 150W per cable.

If you use both 8-pin connectors on one 8-pin cable, you have up to 300W per 8-pin cable, and 300 > 150. This can cause the OPP (OverPower Protection) of a power supply to trip to avoid damaging something (typically where the power cables connect to the graphics card, as most plastic melts more easily than metal).

Okay thank you so much. I will get that going and will get back to you with results. Hopefully this was the problem because that honestly makes sense. It sounds like something is forcing it to shut off.

Unfortunately your psu is known to have tripping issues with high load GPUs. I'm afraid you'll probably continue to have this issue with that PSU powering that setup.

Unfortunately that did not work. Still same issue.

But it doesn’t make sense. It works perfectly fine when I run Time Spy or other GPU stress tests?

He's right. EVGA GA has issues with Nvidia Ampere. Even with a 3080 the 850w GA shut down. Replace it for a Corsair RMx or XPG Core Reactor for example.

Download MSI afterburner and try turning your power usage down to 90%

 

Edit: you could also download HWinfo64 and pay attention to your GPU power usage as it crashes if you have a second screen.

Yeah, it sucks I know. I had to replace my own PSU for a 3080ti. (As well as a couple customers now). The 3xxx is very "spikey" with their power. Unless you're on a scope you can't get a very clear picture of it. 

 

Take a look at the PSU list here and pick one you like, you'll be good to go:

Hey just wanted to let you guys know you guys were right. Got a new PSU and this monstrosity is kicking ass. Thanks for the help everyone.
