So I just purchased a Powercolor HD 4850, and realised that my computer's power supply is insufficient to run it. The requirements say that i need at least 450w, so I would like you to recommend me a cheap power supply that can run the graphics card without problems. Also, should I actually purchase a cheap power supply or save up for a quality one?
Which power supply do you have currently.? 450W is actually a measure of the total power required for your entire system including the video card.. A good 450W will be enough to handle an overclocked processor along with a single HD 5850..
