Help, will not power up!

Hi

Apologies if this is in the wrong box.

I have just acquired, - at ENORMOUS expense (sic) an OCZ 520 ADJ
power supply and an ASUS A7S8X-MX motherboard, and have deployed
them in an old Dell 486 box chassis with a new 20 GB EIDE disk. ($10.00!)

If I test the power supply with a paperclip on the green lead etc, it comes
up fine, but if I plug it into the motherboard along with a chassis fan
then all that happens when I switch on is the green LED comes on and
I start getting network activity. (Guess its trying to boot from the lan).

Anybody got any ideas as to why it might not like the board, - Its a
500 watt+ model so would have thought it would be ok. Am I missing some
vital signal going back to the power unit to tell it all is well?

Thanks in advance
