will normal ATX Power supplies work on microATX boards?

I was 50% thinking it does, but my friend wants to make shure it will work.
100% from someone besides me.

case-wise you need M-ATX but mobo wise it will work fine

like for instance say you bought a m-ATX computer from a retailer and bought an ATX case with power suply to give the machine better air-circulation. the power suply will work with the mobo so long as it has the same conectors

for instance say its an A64 system and uses the 24-pin board conector and the supply only has a 20-pin connector you are screwed unless you buy an adapter.

does this help?

Well, yes and no. A64 mobos use the 24-pin, just that if you use a 20 pin something wont work right, like your cd-rom drives or IDE HDD.

The 4 extra pins on a 24 pin ATX setup are 2-12v rails and 2 grounds. They are used for processor power.
