PSU problem

[[SAE]DeathEater]

Hmmm well i use 750w on my gaming pc and never had issues and I think on my other old computer  i have 450w PSU and thats nowhere near as good as your computer.

Corsair are good but I'd get at least a 500w psu just to be safe

And the make doesn't matter too much, all it does is supply power after all, just make sure its silenced or is known to be quite silent. And obviously preferally doesn't smoke and make sparks xD
