Do I have enough Watts?

I'm thinking of upgrade to a GTX 660 and my current card is a Radeon HD 5770. They both require the same amount of watts which is 450w and I have a 460w. The Radeon and the Power supply both came with the computer. Here is my computer

More about watts
  1. 460w is duable 500w to be on the safe side
  2. 450w is more than enough, it max power drawn from the card is 140w, the recommendation is a 450w psu.
    The 5770 consumes a bit less than a 660 gtx, but it might do for that psu, it's not a huge difference that will make the psu shutdown or burn.

  3. you should be fine, i have a 430w psu on my 660ti overclocked. It's all smooth sailing.
  4. Alright thanks guys, Im also thinking about getting the NVGA GTX 650 TI cause I don't seem to have enough for the GTX 660
