Which power supply?

[beedubaya]

I have decided I want a 550W power supply for my system, but I am not sure what brand to order. Pricewatch.com has some generic ones for only $20, but there are others, like the Coolmax one I am looking at that is over $100. What should I get? Would a generic power supply be good, or do I need a more expensive one?

What you need to check for is the reliability of them, as in how much of that max output they normally operate at. And the cooling they have, and the connectors on them
