    then how the hell am i runing a 6570 which also need a 400 w power supply?
  3. 450 to 500w is a recommended not a requirement in some cases depending on how power efficient the card is and what quality PSU you have, will determine if it will work. But in more cases than not its better to have at-least the minimum.
  4. so should i buy the card and use it with my current power supply? i dont have the money to buy a new power supply i can only get the card so help me out here
  5. I want to say yes, but you might end up getting and and not being able to use it until you get a new psu.

    Ill do some more research what gpu is your 6570 is it an oem or a 1gb or 2gb give me all details you can about it
  6. Accoarding to this the 550 ti is going to use more than 2x the power sooo I think it might be a no go on the buy until you get a new psu. If it was somewhat close like within 10-20% id say maybe but the difference is too much here.

  7. You may be able to get away with a http://www.hwcompare.com/11888/radeon-hd-6570-oem-2gb-vs-radeon-hd-7770/

    and the 7750 is only 5w more http://www.hwcompare.com/11735/radeon-hd-6570-oem-2gb-vs-radeon-hd-7750/

    I know those aren't the graphics cards your looking to buy but its still a good upgrade choice based on psu restrictions.

    but mine is 2gb ddr3,wouldn't it make a difference.the one given in this website is a ddr5
  10. by yours you mean the 6570 even if they are a little different yours is using maybe a little bit less, this is just a possibility but they should be just about the same.
  11. ok what if i buy the 550 ti and try to run it on my current pc? is there any risk involved? i mean i may buy the card and if it does not work i may use it latter when i am able to get a new power supply.i can use my 6570 till then but i want to be sure that testting the card on my current system wont do any permanent damage.i hope u get my point
