Now when im looking for the power supply is there anything specific I am looking for other than that I need at least 750W to run my computer w graphic card?
Do all power supplies come with the same kind and number of "pins"?
Any suggestions on type of power supply I should get?

  1. My $.02

    $185 Zalman 750W (LED's are bright tho)


    $215 Zalman 850W (peak 1050) Quad SLI certified (no LED's)
  2. you dont need 750w to run a q6600 and a 9800gtx. a good quality 400 or 500w is plenty. here are some psu that will run your system fine. no need to waste soo much money.

  3. Corsair TX 650/750
    Corsair VX450
    Any Seasonic

    Id personally dodge Coolmax and the Antec Basiqs (other antecs are fine though)

    Main thing with PSU is quality. Thats the regulation (close to 3.3,5, and 12 v) Efficiency, ripple and the build quality based on the OEM. Corsair is constantly good working with Seasonic and CWT OEM psus which are great.
    If u have any questions just ask. For reviews check out Jonnyguru.com or Hard OCP. They test PSUs very well
  4. IMO the best deal today is:

    CORSAIR CMPSU-650TX $59.99 after rebate

    Corsair is good for their rebates, unlike some others.

    Hold up there a minute doesn't a 9800 GTX require dual 6-pin power connectors. I think you would need at least a Corsair VX550 - the VX450 only has 1 - to support 2 PCIe power connectors (OK sure you could do evil things with molex to PCIe power convertors):
    450 VX spec: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139003&Tpk=Corsair%20450%20VX
    9800 GTX spec: http://www.newegg.com/Product/Product.aspx?Item=N82E16814133246

  6. Agree with most of the suggestions here (except the ludicrous 700w-900w suggestions)

    Any "Decent branded" PSU in the area of 500-600 will be plenty for the system.

    Corsair, Antec, PCP&C, Seasonic
  7. Check newegg. They have the Earthwatts 500W for $49.99 again. 34A on the 12V rails, and two 6pin PCIe plugs. This PSU is normally $90, so this is a great deal.

    Whats with the odd RAM configuration? Also, what OEM is this? You might be better off just building one from scratch.
