The Seasonic PRIME Ultra 1000W is angling to be the "best" 1 kilowatt computer power supply ever built. It boasts having some of the best power efficiency and delivery on the market, all while delivering features like being fully modular, a fully silent mode, and Seasonic's 12 year warranty.

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. Today we our looking at a brand new Seasonic unit that is part of their PRIME Ultra series. In this review, we will be looking at the 1000W model (SSR-1000TR).

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 40 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.

It's Got To Be Primetime; Right?

Today's PRIME Ultra 1000W is another in a long list of power supplies that we have seen from Seasonic. While Seasonic units have always been good performers in our reviews, with the addition of the PRIME series Seasonic has kicked things up another notch. Today's PRIME Ultra 1000W is perhaps a bit more interesting still because, not only is it a Seasonic unit and not only is it a PRIME unit, it is a member of the top of the line PRIME Ultra series from Seasonic. That definitely seems like it should start things off on the right foot for us today as this unit should be full of "awesome" before even stepping into testing. That said, things don't always turn out as they seem. So, before we get too far ahead of ourselves, let's see what else Seasonic has to say about this unit and then move on to some testing:

Its Ultra-high efficiency and outstanding performance are the fine results of Seasonic’s continuous commitment to innovation and advancement. Improved low-load efficiency, highly suppressed ripple noise and a generous 12-year manufacturer’s warranty are just some of the characteristics that set these series apart from other power supplies on the market.

Seasonic has included a PSU tester in the box that will let consumers perform a quick and easy jump start on the power supply. Each PRIME Ultra Series power supply will also ship with a SATA 3.3 adapter to support the "Power Disable" (PWDIS) feature of the newer, high-capacity hard drives. The inline capacitors on the cables were removed, which takes away the bulkiness inside the system. To maximize flexibility, the 180-degree SATA connectors ensuring more flexibility and easier installation

Let’s move on now and see what we can expect when a user purchases the PRIME Ultra 1000W power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
