Hi. My name's petru, and I would like some opinions from you guys. I have built a system and after a few minutes it turns down and does not even let me turn it back on, I think it may be the PSU. The specs are: fx 8350 , MSI 970 motherboard, gtx 770 4gb ram, 8gb DDR 3 2100mhz, and the PSU is corsair 350. I think it has only 350 watts.. Do you guys think I should upgrade the PSU? At first I thought it's from the ram memory cuz I had 2 different ones.
