Being based on Seasonic M12D, XFX 750 W Black Edition is as good as this model from Seasonic: very high efficiency, voltages very close to their nominal values (3% voltage regulation instead of 5%) and very low noise and ripple on its outputs. Plus we could pull over 900 W from it! The main difference between these two power supplies is the presence of a single +12 V rail on the XFX version. On pricing, XFX has the absolute advantage. Seasonic M12D 750 W is being harder to find these days, and costs USD 10 more than this model from XFX.

But it faces a hard competition from Corsair HX750W, which is also being sold for USD 150 and has similar performance. Therefore choosing between XFX 750 W Black Edition and Corsair HX750W is just a matter of personal taste for one brand or the other: both are terrific products.

In summary, XFX 750 W is an outstanding 750 W power supply, with a nice price tag for the user that is looking for a high-end power supply.
