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

    This could do it without hiccups:

  2. u will need 750 w to be on the safe side get xfx it is relable and cheap
  3. seasonic, xfx, nzxt, corsair V2 series, thermaltake toughpowers, antec
  4. 750W should do - never compromise on a PSU!
  5. Awsome im looking at a Toughpower 750w, does anyone of an opinion about them or should i be looking at a corsair
  6. 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
  8. 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 -

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

    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.
  11. 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. :sol:
  13. i own this PSU - been real solid for me;

    awesome work with the bundle as well...cablemanagement is a breeze

    for 850W's

    i'd choose the NZXT if going 850W's
  14. 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..
  15. 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.
  16. 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.
