XFX 850 W Black Edition is identical to Seasonic M12D 850 W, but with a more aggressive looks and costing a little bit less (USD 210 vs. USD 230 on the day we published this review).

Like M12D, XFX 850 W Black Edition is a high-efficiency power supply presenting extremely low ripple and noise levels and great voltage regulation.

The only negative point we can see on this power supply is the presence of “only” four video card auxiliary power connectors, preventing you from installing three high-end video cards without the use of adapters. Since this is a power supply targeted to high-end users that may be interested in running three-way SLI we would prefer to see six video card connectors on this unit.

Nevertheless, this is a terrific product for users looking for a high-end, high-quality 850 W power supply.
