Is this power supply sufficient for these GPUs? Also, which GPU?


Oct 17, 2012
I am hoping to get a new video card and PSU for Christmas, but need to know if the power supply I want is enough for the video cards.

Video Cards I am looking at (also tell me which is better):

ASUS Radeon 7750 1GB

Geforce GTX 550 Ti 1GB

Power Supply:
Corsair CX430

I understand that the Geforce is better, but that it takes much more power. Which should I get, since I am upgrading an old desktop?
I would like some statistics/facts to back up answers, thank you very much!
