The problem is that I can't get it to boot.
When I press the power button, the CPU LED blinks red and the cpu fan spins for about 1 sec, then the whole system shuts off, then restarts, to no avail. All the other leds seem to be ok. All the psu are connected correctly to the motherboard - including the one that provides power to the cpu.
When i remove the 8-pin power supply to the cpu - the CPU LED constantly blinks red and the whole systems seems to be running nonstop - though nothing displaying on screen as one can expect.
I'm wondering, might it be that my psu is too low - 600W with this spec? Tried with my older psu - but didnt give me any answers since it is even lower.
