CPU: AMD FX-8350 4.0GHz 8-Core Processor
GPU: XFX Radeon RX 480 8GB XXX OC Video Card
Motherboard: Asus M5A97 R2.0 ATX AM3+ Motherboard
Memory: Corsair Vengeance 8GB (1 x 8GB) DDR3-1600 Memory
PSU: EVGA 500W 80+ Bronze Certified ATX Power Supply
OS: Windows 10

I just built this new gaming computer. I have downloaded a few games and after a couple minutes of game play in high settings, my screen goes black, and requires a hard-restart. The lights on my computer and fans are still running, but it is unresponsive with no image. I have ran 3DMark and it crashes everything time during the first test and/or the first Graphics test.

Today, I tested playing my games in ultra-low graphics, and was able to play for about 45 mins, and did not crash.

I have uninstalled and clean sweeped drivers, and reinstalled. Window tested my RAM, found nothing (no disk drive to to memtest).

CPU runs about 38-45C and 30% usage when games are running. GPU runs 37C idle, and runs about 72-80C in game. GPU fan is running at 772RPM. (from SpeedFan)


From my research, I was thinking this may be a PSU problem. My graphics card on Newegg recommends a 550W PSU, Min. req is 500W. But I am thinking about returning my PSU tomorrow and upgrading to a 650W to test it out. Next step is changing out my GPU if this does not work.

Is playing with higher settings requiring my GPU to consume more power so my PSU can't keep up and then crashes? A higher Watt PSU fix this? Or is it a bad GPU?

Any words of advice?

The short answer to your question at the end is yes. The rx 480 can consume at least 155 watts vs as low as 30 watts at idle. At stock clocks under load the FX 8350 pulls 213, and well over 350 when overclocked. The remainder of the system we have to assume pulls at least 50-75 watts.

Best case scenario under full load it could be pulling upwards of 443 watts. But not every situation is the same. You could be pulling well over 150 watts over that. I would recommend getting an EVGA Supernova V1 750. It's at a pretty good deal right not on newegg.

Sounds like a bad PSU alright. 500W should actually be enough, if it's a good unit. However the EVGA 500 80+ is a cheaper unit and it's possible it just can't supply it's rated wattage at the correct voltage.
Yes, running high settings requires more power, which is probably why the crashes didn't happen on low. Get a larger and preferably better model PSU and see what happens.

Thank you, I was looking at this one early. This review threw me off tho.

"This review is from: EVGA SuperNOVA 750 B1 110-B1-0750-VR 80+ BRONZE 750W Semi Modular Includes FREE Power On Self Tester Power Supply

Pros: Supported my R9 270x

Cons: Doesn't support the Rx 480 12v rails to weak"

I have the RX 480, are 12V rails really too weak?

Thats actually a misinformed user, the RX 480 needs at least 75 watts from the PCIE slots power which is on it's own 12v rail, and the other 225 watts from the PCIE connector, each supports 240 watts, and there are 4, two combined sets for a total of 480 watts, one for PCIE power and one for system power. This is done to reduce temps.

Awesome, thanks again! When it comes to details like that, it goes over my head. But I took your word for it and ordered it before the sale stopped. Hopefully this works!

Hi, so I bought the PSU you recommended and hooked it up. I am still running into the same problem as before. Is it possible I got 2 bad PSUs? Or what is the next step in your opinion? Try a new graphics card? Or should I maybe reinstall drivers? If its the drivers, do you possibly have a little walkthrough you think is best so I can see if I did it properly.

Thanks again.

It's extremely unlikely you would get two bad power supplies. The next two would be the motherboard or the CPU. Start by swapping the motherboard out then move on to the CPU. If you contact Asus via a problem ticket on their support page they are generally very good at assisting with narrowing down the source of the problem.
