Seasonic G-Series: G-750 Power Supply Review

Seasonic is a long-time favorite computer power supply builder of almost all editors here at HardOCP. Seasonic builds some of the quietest, most reliable, and well liked PSUs on the planet. Today we see how its modular 750 watt G Series rounds out the top of that product line.

Introduction

In the power supply realm, when consumers think of quiet and efficient power supplies one of the first companies that comes to mind is Seasonic and today we have our sixteenth look at a Seasonic branded unit. This review covers another model in Seasonic’s recently launched G Series, the G-750 (SSR-750RM Active PFC F3).

Seasonic is one of the older companies producing consumer power supplies having been founded in 1975 and entering the PC power supply production market in 1980. During that more than 30 years as a company Seasonic has cultivated lines of power supplies that are today some of the standard bearers for efficiency and quiet computing. This focus, and their reputation for quality, has lead to a real explosion in production as Seasonic can be found providing OEM services on various model lines for Antec, XFX, Corsair, PC Power and Cooling, and of course under its own Seasonic brand.

The Seasonic G-750 is the 16th power supply we have seen from Seasonic and it is the second member of the G-Series of power supplies we have seen from Seasonic. We would say that the previous G-550 was an excellent power supply so we would expect much the same today from the G-750, however all of the previous Seasonic power supplies we have seen have been excellent power supplies to date so that wouldn't mean a lot. It is a rather impressive streak as over the last 6 years we have yet to see a real flop out of Seasonic. With that impressive streak on the line today, what does Seasonic have to say about this more mainstream G-Series offering:
