I've been experiencing instability with my system, and I'm beginning to suspect that the PSU is either faulty or under-provisioned. I'll get random crashes (reboots, more specifically), mostly when doing something intensive on the system like starting up a game. Looking at all the crash logs, I can't really find any errors that make sense to me. When the system goes down, all the lights & fans all die at the same time as the screen, then after a couple of seconds it comes back on and reboots.
I have a Corsair SF600 SFX PSU which is only 600W, and I'm powering a Ryzen 3700x, a AMD 5700XT GPU, a 1TB M.2 SSD, 32G ddr4 memory, 2 case fans, and a water-cooling pump. Plugging all of that into a calculator says that 600W is exactly enough, but is that right? Or could power-usage spikes be pushing things over the edge?
Edit: Sorry, CPU is a 3800X not 3700X. Just FYI
To my understanding you want some headroom for your PSU for spikes of power draw or moments like when large appliances start up. Ive certainly had psu's as the cause of failures like that so it seems like it could be the case. Maybe you could get a 750w with return policy and try it out. Worse case you can just return it within that period!
Yeah seems like a good move, Corsair makes a 750W version of this PSU that's comparable with the same cables - so I could swap without even having to re-do my cable runs! Seems like it's worth a try. Hopefully I can get it somewhere local though, as I hate returning stuff in the mail. Thanks!
