There are all the different brands and the wide range of power ratings to consider, not to mention the extra features like modular cabling, fan arrangements, and LED lighting.
is a well recognized name in the computer enthusiast's market, but originally for their "enhanced" system memory, not power supplies. They have been in business since 1994, but their line of power supplies is only a few years old, and this happens to be the first review of any one of their products here at Bigbruin.com. They sent over a power supply that includes many unique features, the "HP-580AP 580W Enhanced Power Supply". This unit sports a total power rating of 580W and quad 12V rails, but one of the interesting features is described as "RailFusion technology" which allows the four 12V rails to be automatically combined into one rail if needed.
