Rosewill Tachyon 650W Power Supply Review

Testing results (Regulation & Ripple)

The electrical performance of the Rosewill Tachyon 650W power supply was better than we initially expected. The voltage regulation on all lines is about 1.6%, very good by today’s standards. Ripple suppression is very good as well, with the largest voltage ripple we recorded being 38mV on the 12V line under maximum load.
