We are pulling double duty today in this PSU review as we are putting both the Seasonic Focus GOLD and Platinum 750 watt computer power supplies through our testing gauntlet. Given that Seasonic is holding the top rung in the PSU industry, let's compare Seasonic to Seasonic and look at the value.


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 pair of brand new units from Seasonic. In particular, we are looking at the 750W models in the FOCUS PLUS Gold lineup (SSR-750FX) and the FOCUS PLUS Platinum lineup (SSR-750PX).

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.

FOCUSing on a 750W Duel

Today, we are looking at a pair of units from Seasonic's FOCUS PLUS line of power supplies both of which come in at 750W. Previously, we have seen one other example from this line of products and that was the FOCUS PLUS Gold 850W which turned out to be a great unit and a great deal. A "twofer" that is truly hard to beat. So, today, we certainly expect that the FOCUS PLUS Gold 750W is going to follow in those footsteps to some degree. However, in addition to that unit we have the FOCUS PLUS Platinum 750W which is a new entry into the FOCUS PLUS line of products that slots in just a bit above the previous FOCUS PLUS Gold units. However, with both of today's FOCUS PLUS units fitting into the same general kind of mold we would certainly hope to see both of them living up to the potential that the FOCUS PLUS Gold 850W gave us in the mid-range previously. Before moving on to see though, let's look at what Seasonic has to say about these units:

FOCUS Plus 750 Gold

High performance and great reliability in this new line of small form factor and modern FOCUS+ Gold power supplies are a guarantee for many years of undisturbed and problem-free usage. The FOCUS+ Gold 750 watt power supplies meet the latest ATX and EPS standards and are ready to be sued with any of the state-of-the-art Intel Core i7 Processors. All FOCUS+ Gold products come equipped with a wide range of safety and protection features to safeguard the system components in critical situations and they have the official approvals of the most important safety agencies.

FOCUS Plus 750 Platinum

The technologies applied and the components and materials used in the manufacturing of the FOCUS+ Platinum 750 watt power supply do not compromise on Seasonic’s legendary high standards. This product received 80 PLUS Platinum certification, where efficiency reaches 92 % at 50 % system load. Superior dynamic response, great system stability, maximized 12 V DC rail output and a state-of-the-art fan control system are just some of the features that will awe enthusiasts who become familiar with this power supply. With Seasonic’s 10 years warranty added: it is as good as irresistible.

Let’s move on now and see what we can expect when a user purchases the FOCUS PLUS Gold 750W and FOCUS PLUS Platinum 750W power supplies in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
