PC is shutting down after installing new graphics card!


I just installed a Sapphire AMD Radeon HD 6950 graphics card. When i play just about any game my computer shuts itself down. I have tried cleaning my tower and making sure my system isnt overheating but im not sure what is going on. Any idea?

    corsair 600W $59.99 after $10 off w/ promo code EMCNCNE23 (FREE SHIPPING) code ends today.
  6. Thank ya for the help! if i get a different PSU what is the minimum Wattage that i will need?
  7. Based on reviews 500W is recommended.

    Just be aware there are a lot of crap brands out there that will end up costing you much more than the price difference between a bad PSU and a quality PSU.
  8. Agree with Lycros, corsair 600w will serve you well. For $60 you cant beat that deal. Its not modular but that will cost you more
