Never skimp on a good PSU. Other ones to look for are BFG, OCZ, Silverstone/Seasonic, and Antec.http://www.newegg.com/Product/Product.aspx?Item=N82E16817341010
$80 OCZ 600W StealthXStream
Does it have a 8 pin connector? It said 1 x 6+2-Pin i am guessing that is a 6 pin with a little 2 pin connector that snaps together making it a 8 pin.
This one only has an amp rating of 18A (same as the one if have now) Is that going to be a problem?
Sorry it was 12V I am not sure where i got 24 from. So 12 V at 40 amps.
