Seasonic is back again today with another of its mid-tier computer power supplies, this time the Focus Plus is Platinum rated, which seems to be exceptionally good for a "mid-tier" product. It has a small profile, is fully modular, and carries on the Seasonic tradition of quiet quality at a very affordable $100 price, all with a 10 year warranty.


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 new FOCUS PLUS Platinum lineup. In this review, we will specifically be looking at the 650W model (SSR-650PX) variously listed as the Focus+ Platinum 650W, Focus+ Platinum 650, Focus Plus 650 Platinum, FOCUS Plus 650 Platinum, FOCUS PLUS Platinum 650W, etc.

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.

I Keep FOCUSing but I Think I am Seeing Double

Today's FOCUS PLUS Platinum 650W is the latest in a long line of power supplies that we have seen from Seasonic's FOCUS PLUS series. Indeed, this unit is the fourth FOCUS PLUS Platinum unit we have seen and it is also the second 650W FOCUS PLUS unit we have seen. Prior to this, all of those previous examples have been excellent products. So, today, with the FOCUS PLUS Platinum 650W, we would expect that this unit will also be an excellent product. Perhaps the biggest question will be how this unit compares to other 650W products on the market and to the FOCUS PLUS Gold 650W not if it will do a good job. However, before we get to far ahead of ourselves there, let's look at what Seasonic has to say about the unit:


Seasonic engineers have created a brand new product line based on advanced technology emanating from many years of intensive active research. The result of this development is the solid FOCUS+ Series, which implements modern design and shows outstanding electrical performance. This power supply is small and entirely modular, which will be hard to resist. It is available in 80 PLUS Platinum and Gold efficiency ratings.

Let's move on now and see what we can expect when a user purchases the FOCUS PLUS Platinum 650W power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
