Computer won't power on -- problem with 4 pin connector / PSU
Hi Friends, I planned to upgrated my system so I bought new PSU – Crossair GS600W. When I plug in both the 20-pin and 4-pin connectors to the mobo and hit the power button, the lights flicker briefly and turn back off. When I have ONLY the 20-pin connector attached (ie, once I remove the 4-pin connector), the power supply will stay on (fan running). But system is working fine with my OLD PSU – 450W. The only thing attached to the mobo are the CPU/HSF and PSU.
Please let me know if there is something as my MotherBoard doesn’t support this much of power supply or my PSU is faulty.

You don't need the 4 pin connector; it may not belong with the 20 pin section. It may be the separate 4 pin for the 12v connection next to the cpu socket. I run my old antec power supply 20 pin connector in a 24 pin slot with no problems.
Yes it's separate 4 pin for 12v connection next to CPU...when i'm connecting that my system is not BOOTING / starting - any idea on this ??
