ATX Power supply, BATX Motherboard

Posted on 2004-11-19

Customer just brought in a rig setup with an ATX power supply on an ABIT BATX class motherboard.  The plug for the power supply fits offset in the BATX jack,  and the machine does indeed work.

My question is simple.

"Should it work normally like this,  or is this a lucky fluke?"

I suspect that if they weren't meant to work in some fashion,  it wouldn't have fit at all.

    Accepted Solution

    Yes, it should normally work like this (but, keep reading):


    "Power supply connections to the BTX motherboard design are the same as ATX motherboards so you can use your existing power supply. Obviously new design power supplies will incorporate the new 3.3 volt Serial-ATA power connections."

    So, yes, the power supplies are compatible, but you will not have the extra 3.3V connector for the newer-generation boards.    At some time, a BTX power supply would be better; BUT, using the ATX power supply will not do anything bad (like fry the board).
