System will not boot

[FatalGrin]

Ok guys i have a 990FX Extreme3 Motherboard, AMD FX 8370 8-Core CPU, 16G Ram, Nvidia GTX 760 Graphics card, and a Apevia 900W PSU. This all started when my computer shut off on its own and i smelled something burning/burnt well i thought it was my old 600W PSU so i ordered a new one, the one listed above. so when i was booting up for the first time with the new PSU my system turnec on then off in a split second so i did some research. come to find out it turns on just fine without the 8pin 12v cpu power connector plugged in but of course does not boot all the way. can anyone think of a reason why this is happening?

3rd one today. Crappy PSU. Fire hazard, Shock Hazard and all around a crappy PSU.
Get a EVGA GS 550W.
Your PSU does not even deliver 600w.


If you want something else click my link in my signature that says PSU Tier List. Only buy Tier 1 or 2. Never go below. The PSU is the most important part in a build

Tier Five
Avoid IMMEDIATELY. These units are highly unsafe to use. No such protections added, very thin gauge wiring used, false advertising and too much to list. Reference to a higher tiered unit for a better, money saving and a much safer unit. For your safety's sake, please don't order or pick one up for use in your system. These units are a potential fire hazard and could even kill you, let alone your system.

Thank you for the speedy reply. but i do think i need a more powerful PSU in the 800W-1000W range cause i plan to add another Graphics card in the that build soon
what would you recommend?

This will support a 760SLI or a 970SLI + OC. Your current PSU had false advertising and was only outputting 600ish watts if that. It was bound to break itself or your other parts.
