Seasonic M12II 500W Power Supply Review

by Michael "SKYMTL" Hoenig | March 9, 2008

+12V Ripple

The ripple suppression shown by the Seasonic M12II was very good and the traces on the oscilloscope stayed far below the ATX-specified maximum 120mV. We have seen some absolute disasters in this test and this power supply put down some of very good results.

Subjective Acoustical Impressions

As we have come to expect with Seasonic-built power supplies, the M12II stayed almost completely silent through every one of our tests. Even with in the SLI tests, the fan spun lazily along while keeping the interior of the power supply remarkably cool. We can see this power supply being the perfect companion for users looking for the perfect power supply for their home theater PC since near-silence is the name of the game here.
