You need a solid 650W or above unit, where are you buying from and what is your budget?

FYI a power supply does not need to be SLI capable. Either it has enough power for what you're connecting to it, or it doesn't. SLI or Crossfire certification is pretty meaningless when it comes to power supplies.
A good 650W PSU should be enough for either of the setups you mentioned (3x 9800GTX+ or 2x GTX 280). Could you post what you're planning on doing with that computer? Specifically, is it for gaming or folding?

I just though SLI capable meant it had enough PCI-E 6/8 pin connectors, nothing to do with the amount of power

And the amount of amps on the 12v rail matter too, correct? and the computer would be for gaming. With that being said, how does a Thermaltake Toughpower xt 675w sound?

Basically, they have 400w psu's that are sli capable... not much you can run with those.

has the hardware I.e. the the video card been purchased?

Amps on the rail matter yes but you only need it to be overkill on a power hungry GPU or SLI. Also depends how many 12v rails it has.

Toughpower line is reputable from what I recall. 650 would be fine but if you haven't purchased the cards I suggest something newer forbade one card solution.

Can you fill in your system specifications into your profile. Helps a ton for us to help.

Sorry new to this whole forum deal but I'll definitely do that. Anyways right now i just have a gateway fx6800-01e with 2 9800 gtx+'s in it... I'm just asking for future reference because I'm getting a new mobo and case sometime next month. But I just ordered that Thermaltake Toughpower xt 675w because I also have heard great things about the Toughpower line and because I found it for 60 bucks. How do you think it'll handle sli?
