Seasonic PRIME Ultra 750W Power Supply Review

This new Seasonic PRIME Ultra 750 watt computer power supply is a revision of its previous PRIME Ultra line of PSUs. This alone makes us wonder just how much better Seasonic can actually make these power supplies, given just how great these were last time around. Let's find out if Seasonic has achieved building an even better PSU.

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 are having a look at a brand new Seasonic unit that is part of their newest revision to the flagship PRIME series called the PRIME Ultra series. In this review, we will specifically be looking at the PRIME Ultra 750W (SSR-750TR).

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.

Today's PRIME Ultra 750W is the latest in a long line of power supplies that we have seen from Seasonic. On top of that, it is the first revision we have seen to Seasonic’s flagship PRIME series of power supplies. Since their launch, Seasonic’s PRIME series of power supplies have become some of the real marque units on the market with performance numbers and support that has been second to none. So, today, with the additional revision of this line it seems hard to fathom how much Seasonic could have improved these units. However, no unit is perfect and that applies even to those previous PRIME units. So, in theory at least, Seasonic could have improved on the PRIME units seen in the past in today's new PRIME Ultra. The question becomes then, if they have, how have they improved upon those previous units? To start things off, let’s look at what Seasonic has to say about this unit:

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

With that from Seasonic, let’s move on now and see what we can expect when a user purchases the PRIME Ultra 750W power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
