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 looking at another Seasonic unit that is part of their PRIME Platinum series. In this review, we will specifically be looking at the 650W model in the PRIME Platinum series (SSR-650PD Active PFC F3).
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.
Today's PRIME 650W Platinum is the second unit we have seen from the PRIME Platinum line following the PRIME 850W Platinum in addition to being the latest in a long line of power supplies that we have seen from Seasonic. When we saw that 850W model we, essentially, saw exactly what we have seen from every PRIME unit we have reviewed so far; an outstanding product that has few peers today. So, with today's 650W model we would expect to see much the same outcome and, realistically, that is what will most likely happen. However, every now and again even the mighty fall so we can't take anything for granted. Now, before moving on to see how the mighty have done, let's see what Seasonic has to say about this 650W "second" line PRIME unit today:
PRIME 650 Platinum
The Seasonic PRIME 80 PLUS Platinum certified power supply is rated to achieve 92 % efficiency at 50 % system load. This high efficiency ensures that there is less heat wasted during operation, which in turn not only reduces the strain on the system components but it also lowers the costs of electricity for users. An ultra-quiet, 135 mm Fluid Dynamic Bearing Fan (regulated by Seasonic’s proprietary Premium Hybrid Fan Control) delivers excellent airflow with exceptionally low noise levels. This unit is an ideal companion to an office computer or an environment where noise levels need to be at the minimum.
Let’s move on now and see what we can expect when a user purchases the PRIME 650W Platinum power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
