I have a peculiar problem. I'm building a new system with the following components:
Asus Sabertooth X79 MB
Corsair AX850
i7 3930
Corsair Vengeance 8GBx4 RAM
EVGA GTX660Ti
Corsair 240GT SSD
When I turn the power on in the PSU, the MB standby LED comes on, but no fans go on, and nothing else happens. The PSU is able to power on an old Dell system without problems. The weird thing is that when I hook up the 24-pin ATX from AX850 to the old Dell and keep the 8-pin power from the AX850 on the new Asus MB, the Asus MB's fans come alive. In this hybrid configuration, if I connect the 24-pin power from the old Dell to the new MB, then the whole thing comes alive. I can power on to the BIOS config stage. So, why isn't the new MB not powering on with the AX850?
