Efficiency and Power Factor
Well, this PSU stops just short of notching a record. It has an efficiency of 90% (at a load of 400W), which is 1% lower than the efficiency of the Enermax Revolution 85+. Anyway, this is the second best result ever shown by PSUs in our labs.
The standby source is rated for a current up to 3A. It does its job well. The voltage is always within the norm.
The Seasonic product perhaps does not look as impressive as the Revolution 85+ but in practical terms it is not inferior to its opponents from Enermax and Antec. Yes, one of them is technically perfect, but what’s the purpose of that perfection if the output parameters are almost the same?
When it comes to the effective parameters, the M12D can only be criticized that its output voltages are not very stable. There is no other fault I can find with it. It features low voltage ripple, a very high efficiency, a gorgeous selection of cables, and quiet operation at low and medium loads. Thus, it will make a perfect power supply for a home computer.
The recommended price of this PSU is $299.
