You've got an ATX PSU on that computer (most likely...unless ur using a seriously old comp)How do I know if I have a ATX power supply or AT.
Dont quote me on this but if the plug fits then its good to go. They are made (relatively) idiot proof.Hmmm I hope so I am trasnfering it from my older computer the big connector that goes on the mother board looks like its missing on copper thingy while the other connector isn't that may mean its differnt right?
