Thoughts on this PSU...

That psu is more than enough for your computer, and its definately a good choice.
 
power supplies are sometimes i believe overated .

I will tell you why , when the whole quad thing was approaching us there came this need that the existing power supplies wont be enough.

Anyway i bought one thinking let me get ready for the double GPU that comes out. So i went and bought 900watt tagan that came in a leather case.

So later bought the 7950 that came out and guess what it only needed one of the 4 or 5 pci plugs i got with my PSU and i had two with my old Tagan.

What a waste. :(

It's four, not five.

And it's the OEM quad-GPU cards that require two PCI-e connectors each, not the retail ones. The retail ones just pull nearly twice as much amperage out of a single connection. It doesn't mean they have fewer connectors, therefore use less power.

And the fact that your PSU is 900W has nothing to do with how many PCI-e connectors it has or how many you need. It could be a 900W and have one PCI-e and that doesn't change the fact that it can still put out 900W.

In other words, you completely failed to point out how your PSU is "over-rated." There's plenty of 550W and 600W PSU's out there that CAN'T do high end Crossfire, 7800GTX is SLI or any quad-GPU. I certainly wouldn't try it with an Antec True Power II 550W.

But the OP only has a single x1800xt, so the Antec 550W is more than ample.
