    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
