I have a 420 watt Okia powering 10 case fans ( 9c ase fans : 7 volt i think ) , 3 HDD's ( 2: 40's , 1 :20 gb) 1 cd-rw drive , a 2200+ , my mobo and my 9800 pro all in wonder , and sometimes 1 or 2 sets of cathodes , Asus probe says my says my my 12 v line is @ 12.544, 5 V @ 4.73 , 3v @3.12 and my vcore is @ 1.616 (stock of 1.6)

Your 5v doesn't look to good... Id check it with a multi-meter b4 replacing your PSU..
5v & 3v should be no more than +/- 5%
12v should be no more than +/- 10%

ok thanks

I edited my first post....
Didn't do the math right on your 5v ....Its not so good and very low....

how much is 10 % on the voltages..like lets say this is the 12V..i can't go more than 12.10V..or else it's not good.cuz if thats the case..mine is 12.43V,3.3 is @ 3.38..,

Umm...
Okay here is a math lesson everyone....

12 * .10 (10%) = 1.2

Now when ppl say +/- that means it can either be up to 13.2 (+), or 10.8 (-)
Comprende?
Same goes for other percentages as well..
