Throughout our testing, the ePower Tagan 480W performed flawlessly. From the noise level to the voltage rails, everything stayed within their respective range. Although ePower has brought a number of new things to the table, such as the rubber protection cover for the power switch and RTN grounding connector cable, we were disappointed to see their 20+4 and 4+4 sliding connectors not implemented on this unit. (REVISED (05/10/05) We've been informed by ePower Technology that their new Tagan model will feature these sliding connectors.) As a whole, this was an incredible power supply unit from ePower Technology and would go great in most high-end servers.
