Just upgraded from a XFX r7850 2GB to a XFX r9 380x 4GB graphics card, with a Azza 700W power supply (now 4 years old).

Installed the card, tested out a few games, seemed fine. Played for over 10 hours and then got an unresponsive green screen - and repeated that a few times, every few hours. Then looked online, then updated the drivers. Played for another 10 at least, and then another green screen.

After reloading the game I was playing (Doom 3 BFG edition, should be able to run smoothly at 1080p), I started getting weird random row tearing. Decided to check my voltage plot, and found that while idle, was running just under 0.9V steady, but under load, the base voltage increased slightly, but also spiked to ~1.15V every few seconds. I can't imagine that's good for the power supply or the card.

I've been reading and finding voltage spikes with the r9 380x aren't uncommon. Is there something I didn't do that I'm missing or do I need to buy a new power supply?

Does the symptoms match that diagnosis? Is there something else that could cause my problem besides a failing power supply?

Ok, got a 80 gold certified EVGA 650W power supply. Just installed it and everything seems to work. Still getting row tearing and the CPU voltage still spikes to similar levels playing Doom 3.

Seems my power supply might not have been the culprit :/. Maybe a bad card? or bad drivers (on 16.3.2)?
