i've got an antec true550 550w ps. i got a new motherboard and it's still giving me problems. i'm starting to think it's the cpu. my machine powers up but nothng else happens. i've tested all parts now except the cpu and the ps (both bought new). the reason i think its the cpu is my new ram has led lights on them to let you know how much work they're doing. in my other machine they're running perfectly, in the busted machine they're aren't lit up at all, as if they're doing nothing. i'm thinking they're not doing anything in this machine cause the cpu is dead so they're ISN'T anything to do. make sense? tomorrow i'm getting a new cpu and ps to test them. sigh...nothing is ever easy.
