Seasonic PRIME 1200W Platinum Power Supply Review

With BIG Power comes BIG Responsibility! How does Seasonic go about handling all that power with its new PRIME 1200W PLATINUM PSU? Given Seasonic's excellent track record when it comes to high-end PSUs, we have high-end expectations. Once you see the incredible price you will almost have to buy one. Really.


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 our looking at a brand new Seasonic unit that is part of their PRIME Platinum series. In this review, we will specifically be looking at the 1200W model (SSR-1200PD ).

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.

PRIMED For 1200W of Power?

With today's PRIME 1200W Platinum we are looking at another unit in the long line of PRIME based units that we have seen from Seasonic. Today though, we are seeing the largest capacity unit to date as this unit comes in at a whooping 1200W. Furthermore, this unit is in the Platinum series so this unit should slot in right in the middle of the PRIME offerings (between Gold and Titanium/Ultra). The good news about all of this is that, to date, none of the PRIME units we have seen have been anything but excellent products no matter if they were from the Gold, Platinum, Titanium, or Ultra lines. So, we certainly have high hopes for the PRIME 1200W Platinum today. However, before moving on to test that let's see what Seasonic has to say about this unit:

There is no doubt that this power supply is a top choice! Its 80 PLUS Platinum certification guarantees extremely high efficiency in all modes of operation. This unit does not make compromises on electrical performance as it features excellent dynamic response and near-perfect voltage regulation. Fully modular cables will grant you user customizable build options and the gold plated connector terminals lower current transmission resistance to increase overall power efficiency. If you are looking to build a high-performance dream system, then this is definitely going to be your dream power supply to power it!

Let’s move on now and see what we can expect when a user purchases the PRIME 1200W Platinum power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
