I have this PSU in my Alienware Aurora

Alienware™ 875 Watt Multi-GPU Approved Power Supply (Standard with Intel® X58 Architecture)

I can't find the specs on it anywhere.
I think the wattage should be enough but I read the 7950s crossfired require ...

The power supply should also have a maximum combined +12 Volt continuous current rating of 45 Amps or greater and have at least four 6-pin PCI Express supplementary power connectors.

I don't know if I have that :(
I bought this Alienware like 2 or 3 years ago I can't remember exactly.
