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
10GB DDR3 RAM
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.

Nominal input voltage range:
100-127V/3A (50-60Hz)

* This power supply has an LED to indicate a possible failure condition when LED is off and power is connected.
