Seasonic G Series 550W SSR-550RM Power Supply Review


Testing results (Regulation & Ripple)

The electrical performance of the Seasonic G Series 550W power supply is exceptional, especially considering the market it is aimed at. We found the voltage regulation to be more than satisfactory, with the power supply maintaining it at below 1.4% on all of the three voltage lines, while the ripple suppression is nothing short of outstanding, peaking at 26mV on the 12V line under full load and just at 10mV on the two minor voltage lines.
