Help with PSU

[shadows1123]

So I've been looking on the eXtreme PSU Guide, and it recommended about 800W. But the Corsair site recommended their 950W. My system is:

2500K
ASUS P8Z68-V PRO
6950 2GB (Twin Frozr III)
SSD
Plenty of HDDs and add-ons

and I do plan on overclocking and Crossfire-ing, but not immediately. i would like a future-proof psu.

I have the Corsair HX850 in my cart, but is that enough?

Thanks

More then enough a HX750 could run that easily in Xfire with power to spare.
Calculators are a rather recent feature added by manufacturers to oversell/upsell units you really don't require.
In 2009 i think there was 2 or 3 calculators around = now everyone has one with exaggerated recommendations.

and 750W is enough for strongly overclocking the cpu and both gpus? and with room to spare (so as not to overwork the psu)

This review is using a more powerful system.
And full system power is @500W = 250W power to spare if using a 750W psu.

Get this one if you have a spare power cord (it's an OEM model). Single +12V rail @ 70A, 80 PLUS Silver and you can't go wrong with Seasonic.
