Seasonic FOCUS GM-650
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. Seasonic is the OEM and ODM of this unit. 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 to 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 among many more. Today, we will be looking at one of Seasonic’s own branded units the FOCUS GM-650 (FOCUS-GM-650/SSR-650FM).
In FOCUS, Or Out Of FOCUS?
The Seasonic FOCUS GM-650 is the first power supply we have seen from Seasonic here at TheFPSReview. Certainly, though, we are familiar with Seasonic as we have seen a lot of their power supplies over the years in other avenues. However, this particular unit is interesting in that it is a revision/update to their well-known and well-received FOCUS line. So, as this product is coming to us with a bit of a pedigree we will certainly expect it to perform like that pedigree. However, before we get too far ahead of ourselves, let’s first see what Seasonic has to say about this unit:
The newly upgraded FOCUS GM series is the successor to the FOCUS Series, which became an instant the top seller in the power supply market after its launch in 2017. Besides the small change in the series naming, the PSU housing and its packaging are also updated to be in line with the concept of the OneSeasonic Initiative.
80 PLUS GOLD
Seasonic was the forerunner of creating the very first 80 PLUS® Gold certified power supply on the market and since that time it has built a very popular Gold series lineup that covers a full power range of power supplies with impeccable performance and efficiency.
The highly efficient 80 PLUS® Gold certification guarantees greater than 87 %, 90 %, and 87 % efficiency at 20 %, 50 %, and 100 % operating loads, respectively. The clear advantage of buying a power supply with an 80 PLUS® Gold rating is the fact that the less energy gets wasted during power conversion, the lower the operating costs will be for the user.
SEMI-MODULAR CABLES
Some cables are permanently attached to the power supply (most of the time the 24-pin and the 8-pin ATX power cables) and the rest of the cables can be used to connect the rest of the available components.
S2FC – SMART AND SILENT FAN CONTROL
The intelligent thermal circuit feature is designed to find the optimal balance between the necessity to cool the components and the need to run the power supply in the most silent manner possible.
FLUID DYNAMIC FAN BEARING
High-performance Fluid Dynamic Bearing (FDB) fans are designed to take advantage of the impact absorbance effects of oil. They are extremely reliable and generate considerably less operating noise and heat than ball-bearing fans. The lubrication of the bearing surface reduces friction and vibration and therefore lowers overall power consumption. Due to the effortless, quieter rotations and its robust construction, this reliable fan technology also greatly increases the lifespan of the fan.
Let’s move on now and see what we can expect when a user purchases the Seasonic FOCUS GM-650 power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
