Just built a new system with the following problem components:
Corsair 650w PSU
Gigabyte Super OC GTX 560
ASUS P8Z68-VPRo motherboard
I turned the machine on first without installing the graphics card and it turned on fine. I then installed the card and powered on, but nothing happened at all. Seemed no power was in the system (LEDs are however alight on the motherboard) I removed the card, but the system still wouldn't power on.
Assumed the PSU was faulty and had it replaced.
Next time I installed the graphics card at the start and no power again. Not even a flicker of life (literally nothing at all). I removed the card and still the same problem as before.
Is it possible the graphics card is faulty and immediatly kills my power supply before the system even flickers? Or have I had 2 faulty power supplies? Or am I just making an amateur instaltion mistake?
