See the internals of a generic 500 W power supply, how much power it can really deliver, and the differences between a good and a bad power supply.
"We decided to take a generic 500 W power supply and test it using the same methodology we use for "branded" units. The idea behind this review is to be as much educational as possible and answer a few very important questions: how much power a generic power supply can really deliver? What are the differences between a generic power supply and a "branded" unit? Is there any danger for my equipment to use a generic power supply? Why generic units cost so little? Read on and see our findings."
