HD 7770 on a 300W power supply

[DWoodhouse]

Hi Folks,

I currently own an HP Pavilion p6-2104ed with an Eyefinity Radeon HD7570 (that came with it)
I'm looking to upgrade my video card as the current one is starting to develop some issues

My question is: will a HD7770 run on it? Unfortunately the computer only has a 300W power supply (not planning to upgrade the power), though I did see a similar topic where the HD7770 was referenced for a 300W PSU

Full specs for the pc are at http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c03280789#N1225

For the power supply it just says:

Internal 300W (100V-240V)

Form factor: Internal ATX
Total wattage: 300W
Nominal input voltage range:
100-127V/6A (50-60Hz)
200-240V/3A (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


If it runs: great! I see its specs are quite a lot better that the 7570.
If not: any suggestions on a different video card that will run?

A GTX 750 or 750 Ti should work with a weaker OEM PSU like the one in that HP machine

The guys over at HP support tell me the 750 has "uefi" enabled and that might cause issues. Also some models require 400W.
Any suggestions on this, or other video card ideas?

Woops, forgot about this post

If you're concerned about that, then the 7750 would be the next best choice
