Seasonic Snow Silent 750W Power Supply Review

Seasonic is without a doubt the "best" computer PSU designer and builder in North America in our opinion. It has continually made award winning enthusiast class PSUs which is simply not easy in today's market. Six of its last eleven units reviewed here have "only" produced HardOCP Silver awards though. Do we have a new Gold [H] today?


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 21st look at a Seasonic branded unit. This review covers the 750W model in a new line of power supplies for Seasonic, the Snow Silent 750W (SS-750XP2S 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.

As Pure as the Driven Snow

While today's Snow Silent 750W is the latest in a long line of power supplies that we have seen from Seasonic, including three 750W models, it is the first member of the Snow Silent line we have seen. Since the introduction of the X-750 Seasonic has been on a serious roll with award winning after award winning product. So, today's Snow Silent 750W certainly has the pedigree to be a champion (not least of which because it is somewhat the spiritual successor to the X-750). Then again, so did all of Secretariat's offspring and they were busts for the most part. So, while pedigree may be indicative of potential it is not always predictive of actual performance so we are very interested to see how this Snow Silent 750W stacks up against the competition. Before moving on to see if the Snow Silent 750W is a winner or an also-ran, let's see what Seasonic has to say about this unit:

The unconventional exterior of our newly designed Snow Silent 750 power supply is surely to surprise many. Undeniably, the stylishly white, sleek finish looks very different from what people are used to seeing on a Seasonic product. It is, however, the top performance built into this unit that truly takes it to a higher level. Customers wanting to build a quiet gaming-, home theater-, or office computer will be delighted with the advanced features of top quality, this 80 PLUSآ® Platinum certified, fully modular power supply with a modern look.

Moving on now, let’s see what we can expect when a user purchases the Snow Silent 750W power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
