Is this psu enough?

[majju2]

I will have a sabertooth x54 mobo (99%)
Intel Corei7 950 3.06GHZ
ATI HD6970 (but I want a crossfire in the coming future)

will any of these be enough for these parts(& sli in the future) and which one is best:

Xilence 800W -91Eur
Corsair -850W TXEU- 133Eur
Coolermaster Silent Pro 850W – 138Eur
Coolermaster 750W GX - 101Eur

If you want to use crossfire, then I would go with the corsair. The xilence only comes with a one or two year warranty, depending on your area. Corsair is considered superior to coolermaster with most of it's units.

I would take the Corsair 850TX of that bunch, but i would also take a look at the 750TX and the XFX units as they are solid and over here tend to be cheaper than the Corsair units while giving similar performance.

I would stay away from the Xilence as that seems too cheap compared to the rest, and steer clear of the Cooler Master GX 750, the GX line up has major ripple issues and has failed multiple reviews.

There is also the Corsair 850W HXEU-175Eur
but I tought i was a bit expensive.
so the Crosair 850TX would do the job?

The 850TX is more than enough for 2 6970's, a 750TX could handle it, you dont need to get the HX version instead.

Thanks I will go for it then!
Last question, I don't think are much power consumption difference between 2 6970 or 2 GTX580 ? Cause I'm not sure which one Im getting yet
