Question Is my PSU inadequate for my system ?

[Sjouwerd]

Hi all,

So I've been experiencing random crashes/black screens during gaming on my RTX 2080 TI. However when I set the power limit of my GPU to 140W it will not crash. This will result in poor gaming performance however (low FPS and whatnot). So it seems that spikes in power will cause my PC to crash..

PSU: SFX 750W
CPU: AMD Ryzen 7 5800X
GPU: RTX 2080 TI
RAM: 2 x 16GB DDR4
Storage: 2TB SSD and 1TB HDD.

Is it correct that my PSU might not be good enough to support all of this?

SFX 750W PSU.

What's the brand and model of this PSU?

I think it is from NZXT and came with the case.

SFX

750 watts is more than sufficient to power your system. However, if your power supply happens to be malfunctioning, then it happens to be malfunctioning.

What precisely has been happening? Is the computer power shutting off? Is the computer restarting? Is the game crashing to desktop? Does this happen for all games, or a specific one?

If the game is crashing to desktop, then I would recommend downloading and running DDU (Display Drivers Uninstaller), Updating the motherboard BIOS version (downloaded from motherboard manufacturer website), and installing the AMD chipset drivers (downloaded from AMD.com).

If the computer is restarting then I would assume that the issue is most likely caused by your RAM or power supply. For the RAM, verify that both sticks are in the slots recommended by the motherboard manufacturer. If the power supply, then I would borrow or replace your existing unit to test for stability.

By the way, what is your motherboard manufacturer and model, and what BIOS version and date is it?

The computer is not shutting off but it turns to a black screen. Sound continues for about 10 seconds and then stop. Fans GPU will keep spinning and RGB stays on as well. Have to hold down the power button for 5 seconds to shut the system off. It's the only way out.

DDU wipe and re-install was done, BIOS updated this weekend but no change. AMD chipset driver, not sure how to update that but I'll look into it.

As for removing RAM: I have a rather compact case and I am afraid that I cannot put everything back in place once I take out the RAM sticks. It is a NZXT H1 case. I did not build the PC myself so therefore not sure if I can put everything back in the right place after that. I am also not a PC expert let's say

I can try to run a windows diagnostic memory test for the RAM?

Asrock a520m-itx/ac is my motherboard and like I said it has the latest BIOS since this weekend.

On paper that PSU is enough, but i real world it is not. My last computer was a 8700k, 2080 Ti, and a Evga 850w G2 PSU and it ran into all the same issues your having along with random reboots. I ended up installing a 1600W G2 i had laying around which solved all problems, had i not had that i would have bought a 1000 or 1200w PSU.

The transit power spikes on these cards are bad and is recommended to use a 1000W ATX 2.0 or 850W ATX 3.0 power supply to handle it. The new ATX 3.0 have better specs to handle these spikes.

It is just as likely that the card is failing. By reducing the power limit you are sparing the card not the PSU so much.

If your computer is indeed doing that daily and random boots suddenly..
It's trying to tell you the psu is on it's way to die within days or a week or so.
Now psu wise, I suggest this and yes I have a rtx 2060 super clock and it hardly bothers this psu at all.

If you plan on getting a newer gpu card next year, I would suggest:

So my pc started freezing/crashing when not in game now as well. For instance when browsing the internet… so at that moment there is no peak in GPU usage causing the PSU to run out of juice. Could it still be PSU related then?

I’m lost for words.. don’t have possibilities to get a new system now if needed 😖

A 2080 Ti is a poor performer relative to it's power consumption. It might be time to upgrade. Even a 16gb 4060 Ti is worth considering as a replacement, if you really need the extra VRAM. The reduced power consumption will pay for itself over time.

 

[QyInvoLing]

It's either the PSU or the graphics card to blame.

You might not think the card is not doing anything, but just a webpage switching the card from a 2d graphic to 3d graphic can spike the power draw on the card to trip the computer.

Most software cant even register the power spikes as they happen so quick the software doesnt have enough time to refresh to catch it.


I went through the same thing where one of my two monitors would drop out for 5 seconds and then come back on. Thought it was the monitors so i bought new ones....didnt fix the issue. Replaced the graphics card, that fixed the monitor issue but then would get random freezes and crash/reboots. Finally replaced the PSU and all issues stopped. Through all that my brother got my old monitors and gpu for a nice upgrade to his system.

Thanks. Also seeing this message now after a crash in the event viewer.
So possibly GPU crash due to power spike and PSU cannot keep up?

Unfortunatley I'll not be able to do any work on the PC itself so I'll have to bring it to a shop. I want to try and give them as much detailed info as possible to prevent them from doing a lot of testing causing high costs on my end.

What's the exact brand and model of the RAM?

What BIOS version is the motherboard running?

See attached thumbnail.


Bios is the latest one available on the website from Asrock. I updated that last week.

Black screen but still running normally GPU issue.
PSU power issue normally means hard shut down.
