Verdict
Cooler Master GX III 750
8.2 / 10 Expert Rating
A well-rounded 750W Gold ATX 3.1 unit with a strong warranty, right in step with the best in this wattage class.
Fractal Design Ion SFX 650W Gold
8.2 / 10 Expert Rating
The Ion SFX line is Fractal's answer to mini-ITX builders, and the 650W Gold unit is enough for a mid-range GPU in a Fractal Terra or similarly compact case without stepping up to SFX-L.
