I have a Windows 7 64bit pc along with i7 core processor and Antec 500W power supply. I am using a HD 6770 and am now looking to upgrade the graphics card to GTX 560ti. I have read that this video card needs 500W power supply and I have a minimum Antec 500W power supply already. I wanted to know if this PSU will be enough or there will be problem running this card? Thanks for any replies.
