hello,

i built my own pc 4-5 months ago and it just keeps crashing. i think its my PSU or my GPU that is causing this.

iff it crashes i just get a black screen and 2 secs after i get a light gray screen.

when i restart my pc then and i get back at desktop page i see on GPU tweaker that my GPU is around 50°C so i dont know.

but what i think is that my PSU doesnt offer enough Voltage.

i have a CX500M from Corsair
and GTX 770 GeForce

but when i went to the store to buy my PSU the guy said that i dont need a 650W PSU as Nvidia recommends. so i bought the 500W

can anyone help me ?

He is correct that a 650W PSU is overkill. It is common for AMD and nvidia to over-recommend wattage sizes in order to avoid things such as lawsuits about incorrect specifications and requirements from upset consumers. Nvidia GPUs are very lean and efficient on power and I can run my power guzzler 7970 with an overclocked i5 4670K on a 550W PSU no problem. As for your idle temperature, mine idles at 62°C so yours isn't that hot. Most GPUs tend to idle around 40-50°C. Also are there an specific prerequisites that cause this crash or does it happen randomly?

well it happens allways when i am in-game of course. mostly it only crashed at Elder Scrolls online on ultra settings then i lowered my settings and it still crashed. Same with DayZ. and now it starts crashing in League Of Legends also.. and that isnt a very high demanding game.. now it crashed like 1 hour ago and i capped my fps at 60 cause my monitor cant handle any more. but im still gonna buy a higher wattage PSU. i dont want to take the risk to ruin my whole pc

If it only crashes in game and your GPU is not near its peak power draw usage then I don't see it as being a PSU problem. Sounds like unstable drivers (but that would normally result in a BSOD) Try to find a friend who'd let you swap GPUs for a while to test your build out and if the crash still happens then I'd replace your PSU and if it still occurs replace the GPU. Oh and don't forget to go to your GPU vendor's website and contact them about any problems you may be having with your card. Sometimes they might surprise you.
