First of all, I want to upgrade my computer by little steps due my low money, so, don't laugh about my CPU, and I still have DDR2 I have this PC now: ECS AT780GM-A Athlon II X2 250 3.0GHz 3GB RAM DDR2 800MHz XFX ATI HD4670 1GB DDR2 Western Digital 160GB HDD PSU generic (400W) Now I want to buy a Radeon HD7770 1GB GDDR5, but I'm afraid i'm gonna need a PSU but I don't know. I readed some benchmarks and this card consumes 8W on idle, 50-60W on maximum and 40W on Average. In this page it says that I need 290W, but who knows. Thank you guys in advance!

Not really a good value, I'd pay $5 more and get Antec 400C, which is ironically more powerful and has superior build quality.
