System: GA-MA785GM-US2H board, Athlon II X4 620, 2 sticks 2Gig Kingston DDR2 RAM in slots 1 and 2, 1 500gig Samsung SATA drive, 1 Philips DVD-RW - Antec Earthwatts EA-430D 430 watt power supply.
First tried plugging in JUST 24 pin ATX connector. Turn on, CPU fan spins, devices power up, no post at all - no beeps, no monitor activation.
Then plug 4 pin 12V connector into the half of the 8 pin 12V connector that it fits. Result - nothing - no fans, no devices powered up, just nothing.
Remove 12V connector - fans spin, devices power up, etc.
Replace 4 pin 12V connector - nothing again.
Does this mean anything to anyone? Is the PSU too weak to power the CPU? I'm going to try another PSU / CPU tonight, but I thought I would see if this particular behavior meant anything to anyone.
Thanks!
