300W to 450W: 20 Power Supplies on the Test Bench
 

Many of you have been waiting for us to review more low-wattage power supplies. We have written about power consumption several times in the past, and we have made it clear to AnandTech readers that in most cases there is no need for a high output power supply when 400W to 500W units will do just fine. We picked a collection of such units from high-end manufacturers throughout the market, and in fact we received so many power supplies that we had to split the roundup into two parts. The first part will contain power supplies rated at 300W to 420W while the second part will focus on 500W to 550W units.

Isn't it funny how the corsair and the tagan are exactly the same unit made by Seasonic =P
