Yeah, its junk. Do you see that red switch on the right side of the case? Thats the voltage selector switch, which means its an old design. Efficiency is less then 80%. There is no indication of how much power is available on the 12v rails. And I'm sure if you looked it up online you could find a review of it, and I doubt it would be a good one.
Here is a good one.http://www.newegg.com/Product/Product.aspx?Item=N82E16817139008
$50 counting shipping. It will be $35 if you get the $15 rebate back. The Corsair 400W is a good one, and should provide enough power for most cards. The X2 type cards will be to much as would the new GTX4xx cards, but most everything else should be alright.
