Do you guys know any low-end budget graphics card that doesnt require a strong psu. I don't want anything that is super extream but something that will run games like starcraft 2 maybe on high without any lag and its pretty cheap. I have a 400Watt psu. Its one of those lame psu that came with the case. Its a peace a trash but I want to go in with the graphics card before upgrading my psu
If we knew what the rest of your system was it would help us give advice because we have no idea how much power your computer is currently drawing. We also don't know if your PSU has a 6pin power connector for a video card or not.
With that said, the Radeon 7750 is currently the most powerful card that doesn't require a 6pin connector off the PSU, a 6770 would be a little more powerful while also cheaper, but that requires the 6pin connector. I doubt a generic PSU can power anything better than the 6770, I think an equivelant Nvidia card right now would be a Geforce 550.
