[H]ard|OCP visits the weird world of dual PSU products, which allow the usage of two PSUs in a single system and which are transparent to the end user as they are both controlled as if there was only one.  There are four methods covered; Add2Psu, the Lian Li Secondary Power Supply Starter Kit and both auxiliary and redundant PSUs.  They range in style from the impressive abilities of Add2Psu to string together unlimited amounts of PSU using Molex connectors and Lian Li’s PSU crossover cable to FSP’s 5.25" Booster X5 450W auxiliary PSU and the Athena Atlas 800 redundant PSU which seems more at home in the server room. If you want more power but don’t have a PSU big enough this will show you how to give your existing PSU a helping hand.

"Putting two powers supplies in your computer has been a recurring subject in our forums for years. While the physical process of making that happen is not exactly rocket science, it still can be daunting for some users. Today we show you a few products that make it easy for anyone to double up on the power should your wattage needs increase."
