Looking at that i thought it would work on my Thermaltake 430W http://www.newegg.com/Product/Product.aspx?Item=N82E168...
because of my computer specs:
/\ That power supply.
Intel Pentium Dual CPU E2160 @ 1.8Ghz
1.5GB Ram (1 - 512MB DDR2 800Mhz | 1 - 1GB DDR2 667Mhz)
320GB Hard drive.
16x multi-format/dual-layer LightScribe DVD drive.
So it doesn't seem it would take too much power away from the graphic card? I think i could try right? But then again radeon 4850 needs an 450W or greater..
By the way, my knowledge of computers isn't very good. D:
