remove everything from the mainboard other than the ram, cpu, cpu cooler, - aka graphic cards, usb drives, hdd drives and cables, usb ports (ones that can be removed) and power cables to all hard drives etc, aka power only to the mainboard. and then try.
I once came across a Western Digital Drive that was causing the power supply to trip out.
if it stays on for a little while add each item back in one by one.

hope this helps
