    depends, is your psu of quality, and has a 6 pin connector? according to This the card would eat up too much of your psus wattage on load. and that would be pushing it. unless you had an EXTREMELY high quality psu that can push past its labled wattage, you are going to need a new one.

    if your planning to no overclocking at all and never upgrading parts in the future, get a 380-430w certified psu(I emphasize the word certified, preferably bronze at the least, common choice would be an antec earthwatts for low wattage and works well)
  2. I don't think OEM pc psu carries a 6 pin connector unless it has a non onboard graphic card, and more than likely that you definetely would need to upgrade try: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371046
  3. I went ahead and bought Corsair Builder Series CX V2 430-Watt 80 Plus Certified Power Supply Compatible with Intel and AMD Platforms - CMPSU-430CXV2 to power it... is this good enough?
  4. Hello,
    I am running an HD 6850 on a CoolerMaster eXtreme Power Plus 460w for about 8 months without any significant problems.Your PSU is better than mine.

    You should have no problems ideally.:) Hope this helps.
