Well, I just bought an AGP OC Geforce 6800 GS card... 256MB GDDR3 with 33.3GB bandwith. But I did'nt notice that I need a power suplly @ 350W.... So i opened up my PC and read the label on my powersupply, and it says that it only supports 250W of power... What's strange is that my previus card (geforce 6200) needs 300W of power, but my PC works fine with it.. Do i necissarly need to buy a new power suply just to install my new graphics card? Specs Athlon 3200+ 1GB of memory
