Seasonic M12D SS-850EM
Although Seasonic does not make such ambitious claims as Enermax, its M12D power supply can challenge the Revolution 85+ in a number of parameters. Particularly, it complies with the 80 Plus Silver standard and has an efficiency of 90%. By the way, Seasonic has recently introduced a series of PSUs with lower wattage that are even 80 Plus Gold compliant.
The M12D also features DC-DC converters that I described above in the Antec Signature section.
Packaging and Accessories
This PSU comes in a small box painted orange and black. Its key features are listed on the back panel of the box. Included into it are detachable cables, a pouch to store the cables, an installation guide, a power cord, screws, and a sticker for the system case.
The PSU has a standard Seasonic case painted a matte black against which the silver-and-blue sticker on the fan grid stands out.
There are six Molex Mini-Fit Jr. connectors on the back panel of the case for detachable cables: four for peripherals and two for graphics cards. It is inconvenient that the connectors are all the same color. However, you cannot plug anything wrong because the connectors have different number of pins.
