hmmm i reckon it would work as ATX-2 and mATX both have a 24 piece power connecter ..... so give it a go n tune me if smoke ensues
would this psu work on a p4 atx mobo? can't find any further info on it. http://www.dabs.com/productview.aspx?quicklinx=399V&fb=324&InMerch=1
Yes, it'll work, it's about form factor and nothing else... so long as 250W is enough for your needs choose any form factor you want, as long as it's got the right mobo pin and probably need the 4-pin mobo connector too...
