Seasonic G-Series: G-550 Power Supply Review

The Seasonic G Series PSU is here for review in its 550 watt capacity and it looks to be a return to basics for the company with this being basically a "no-frills" unit that has been released without much fanfare. But the basics for Seasonic usually outline what you truly need in a PSU; reliable clean power with a low sound profile.

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 11th look at a Seasonic branded unit. This review covers a new line for Seasonic, the G Series, with today’s model being the G-550 (SSR-550RM 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 its reputation for quality, has lead to an 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.

Something out of the Blue

The Seasonic G-550 is the 11th power supply we have seen from Seasonic and for modern enthusiast units it falls into the lower end of the capacity spectrum. For a long time, we saw very few truly high powered offerings from Seasonic but in the last couple of years these have made a splash with its high powered X-Series units. As such, today’s G-550 is somewhat of a return to a product segment that we used to be very familiar seeing Seasonic dominating. With this new launch fitting into a comfortable old niche, we are going to have very high expectations for Seasonic and this unit. Hopefully, it will deliver on those expectations. Before moving on, let’s see what Seasonic has to say about this unit:

With little more than a list of features being available, let’s move on and see what we have to look forward to when we purchase the Seasonic G-550 power supply in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
