I'm looking to upgrade my graphics card so that I can play games like Planetside 2 with reasonable framerates, at low/medium settings and at a 1360x768 resolution. The two cards that I'm considering are the Galaxy GTX 650 and Powercolor HD 7770 (both priced A$109).

I understand that the 7770 is a stronger card, but my PSU is 420W (23A across two 12V rails) and I'm getting conflicting recommendations from different sites on the power requirements for the 7770; some say minimum of 450W, some say 500W etc.

Ideally, I would buy the 7770, but i'm apprehensive because my PSU doesn't meet the recommended minimum power requirements. Is it safe to run the 7770 or should I go for the slightly less powerful GTX 650 which only needs a 400W PSU?

Thanks guys :) 

My system:
AMD Athlon II X2 260 3.2GHz (bear in mind that I will be upgrading this sooner or later)
4GB RAM
Gigabyte GT 630 2GB DDR3
420W PSU
2x 500 GB HDD

I would recommend you a new PSU.
It depends upon the company of PSU. Which brand is it of?

7770 is a better buy and would easily run on a Good Brand 420w PSU.

The recommendation is the total power consumption with alot extra Watts included.

I am sure a quality 420w PSU will be able to handle a 7770.
