Hey all, So i am building a couple rigs for my office and always prefer EVGA products so naturally I selected (2) 80 plus gold units from EVGA. One was a 650 GA and the other was a 750. The 650 is perfect, no issues at all. The 750 however (the important rig) is exhibiting symptoms that it was DOA. I have never had this happen with any EVGA products, although I'm sure they have had their fair share. My question is, am I missing something?? It was installed and hooked up the exact same way as the 650 as both rigs have very similar components and same number of drives etc. I used the little tester and it would indicate the power supply is ok. However, the PC wont power on, I just get I/O lights illuminated on MOBO but wont boot. So i put a spare Corsair 750RMX in and like magic PC operates perfectly. So that eliminated front panel and MOBO connections. Any ideas before I RMA this thing, any and all help is appreciated.

Hi
If the power supply fan stays on with the test, it could indicate an issue elsewhere in the system. Make sure to use only the original cables that came with the power supply. Try disconnecting everything else( hard drives, graphics card, CPU, etc) from the power supply and just plugging in the motherboard 24 pin connector.  If it does come on, try adding back the other components one at a time to see which part could be causing the system not to turn on.
