Seasonic PLATINUM-1050 Power Supply Review

Seasonic is one of our long-time favorites when it comes to truly high-end power supplies. The new PLATINUM-1050 PSU claims to deliver excellent power efficiency and does so with a fully modular design. Seasonic is often known designing products with excellent sound profiles. Does the PLATINUM-1050 fit the profile?


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 19th look at a Seasonic branded unit. This review covers a new entrant in the Platinum-Series of power supplies for Seasonic, the PLATINUM-1050 (SS-1050XP3 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.

Replacing a Legend

The Seasonic PLATINUM-1050 is the 5th power supply we have seen from Seasonic's Platinum Series. Previously, among those Platinum units, we have seen units ranging all the way from 400W to 1200W including fanless models. Today's 1050W, though, is somewhat of a redux as it will be taking the place of the older PLATINUM-1000 which was an outstanding unit when we reviewed it 3 years ago. Given Seasonic's previous success with their products in general, and the PLATINUM-1000 in particular, we certainly have high expectations for this unit today. Before moving on to look at this member of the Platinum Series, let's see what Seasonic has to say about this unit:

As has been the case with a number of Seasonic units of late, we really don't have any idea how this unit is going to be positioned from what Seasonic presents us on its product page. However, we can take a fairly safe guess that this is supposed to be the flagship product at the moment given how other PLATINUM units have been positioned and the capacity of this unit. Let's move on and see what we have to look forward to when we purchase the Seasonic PLATINUM-1050 power supply in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality this will become clear.
