Radeon HD 5770 Power Requirement

Hi guys, I'm new to the forum and I just had one simple question for you all. I just replaced an old HP m9340f with an H8-1534, stats as follows:

AMD FX-6200 six-core @ 3.8Ghz
ATI Radeon HD 7570, 2GB dedicated video memory
1.5TB 7200rpm HDD
460w power supply
Windows 8 64-bit

My specific question is: I have an old Radeon HD 5770 that I would like to remove from the m9340f and put into the h8-1534. The 5770's power requirement is 450w. Would the computer's 460w power supply be enough, or would I need to upgrade?

Thank you.

  1. Do you know the brand of the psu?
  2. It's just an OEM. This is the power supply's info pulled off of HP's website:

    Form Factor: internal ATX
    Total wattage: 460W
    Nominal input voltage range:
    100-127V/3A (50-60Hz)
    200-240V/2A (50-60Hz)
    Dimensions: 150mm x 140mm x 86mm (5.9 x 5.5 x 3.4 inches)
    * This power supply has an LED to indicate a possible failure condition when LED is off and power is connected.
