The sad fact with self-assembled Personal computers is that the importance of power supplies are forgotten. This component deserves some weighty consideration, especially since many make the mistake of buying a power supply that provides more than they really need. This obviously ties up money that could’ve been used for a superior video card or processor.
Before you even think of assembling your own PC, you should take a look at AnandTech’s article on Debunking Power Supplies. The money quote:
If people really took the time to analyze system power stipulations, we would see a tremendous increase in sales of 300W to 400W PSUs. The truth is that the vast majority of systems would run optimally with such a “small” power supply. Even if you’re running SLI/CrossFire, you don’t actually need a 750W power supply. (Of course, we suggest purchasing a good quality power supply, as there are certainly “750W” PSUs out there that can’t reliably deliver anywhere near that much power.) To help dispel some myths relating to power requirements, we’ve put together a couple of charts.
