Any quality PSU with good amps on the 12V rails and above 550Watts will power that system.

This could do it without hiccups:

u will need 750 w to be on the safe side get xfx it is relable and cheap

 

[Lutfij]

seasonic, xfx, nzxt, corsair V2 series, thermaltake toughpowers, antec

750W should do - never compromise on a PSU!

Awsome im looking at a Toughpower 750w, does anyone of an opinion about them or should i be looking at a corsair

 

[Onus]

Based on my assumptions about drives, fans, etc. the PSU calculator at http://www.extreme.outervision.com/PSUEngine suggests 643W will be sufficient.
A quality modern PSU has full range active PFC (no little voltage switch) and some level of 80+ certification for efficiency. Seasonic, Antec, Corsair, XFX, and Enermax/LEPA are among the better brands.
In your place, I'd be gnashing my teeth for missing out on the Seasonic X750 for $119 last month; by the first of the year there will likely be another good deal or two.

imo xfx is not very good psu's unless u talking about black edition ones

 

[hellfire24]

6990 is a beast and needs high power supply.for a single 6990,a quality 750w(really more than enough) is enough.for quadfire,don't go below 1kw quality psu.here's a suggestion -

xfx are actually seasonic units with an xfx sticker so you're good with which ever one you get

@ OP - what is you PSU budget...excluding the fans ?

I'm going quality over price so as long as the psu I get can stand up too the conditions then price isn't a huge thing.

Well then, most of the best PSUs are made by Seasonic; whether their own or the ones others (like Corsair and XFX) buy and relabel.

if price is not an issue than you should go with this-

you may find it overkill and yes you are right but when you want to crossfire that dual gpu than this is one the best and most reliable things.

i'd choose the NZXT if going 850W's

Enthusiast Series™ TX850 V2 — 80 PLUS® Bronze Certified 850 Watt High Performance Power Supply..this pus will serve your purpose very well.. i assure you..

I've got a 550W Truepower New in my backup PC, and a Seasonic X-560 in my primary. The latter may get replaced with my older SG-650 if I decide I want another video card; for now I can't help but think the SG is being wasted as my current "bench" PSU.

For a system using a single Radeon HD 6990 graphics card AMD specifies a minimum of a 750 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 50 Amps or greater and have at least two 8-pin PCI Express supplementary power connectors.

When the performance micro-switch is set to use the Extreme Performance BIOS the card alone will be drawing up to 370 Watts (30.8 Amps) from the +12 Volt rail(s).

Overclocking the Radeon HD 6990 with the performance micro-switch in the Extreme Performance BIOS position will increase the power draw and temperature even more.

A reputable brand 750 Watt power supply unit like the non-modular Corsair Enthusiast Series TX750 V2 (CMPSU-750TXV2) or the modular Corsair Professional Series HX750W (CMPSU-750HX), with their +12 Volt continuous current rating of 62 Amps and with four 8-pin PCI Express supplementary power connectors will properly power your system using a single Radeon HD 6990 with ample reserve capacity to handle any overclocking of the CPU and graphics card you may want to attempt.
