When consumers think of quiet and efficient in the power supply realm one of the first companies that comes to mind is Seasonic and today we have our eighth crack at a Seasonic branded unit. This review covers an evolution of Seasonic’s X-Series line of power supplies the Platinum-1000 (SS-1000XP Active PFC F3). The Platinum-1000 is currently slated to be the highest capacity member of this line with an 860W model to follow.
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 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 their reputation for quality, has lead to a real explosion in production as Seasonic can be found providing OEM services on various model lines for Antec, Corsair, PC Power and Cooling, and of course under its own Seasonic brand.
Today's Seasonic Platinum-1000 is the 8th power supply we have reviewed from Seasonic. In addition to being 8th, this is the largest capacity power supply we have reviewed from Seasonic and supposedly the most efficient power supply as well. Indeed, as with any number of units that play the 80Plus game, a large part of this unit's identity is tied up in its claimed efficiency. To be a good power supply though, a unit must be more than just efficient and once we get past that part of the branding we see that Seasonic seems to be putting its best foot forward in that regard as well, or at least its marketing department is:
Sea Sonic Electronics, a leading manufacture high quality and efficiency power supplies for the past 35 years, launches the Platinum Series power supplies in 860 and 1000 watts. The Platinum Series, certified in accordance to the 80PLUS highest standards, offers the newest technology and innovation for performance and energy savings with up to 92% efficiency and a true power factor of greater than 0.9PF. This, combined with continuous power outputs of 860 and 1000 watts, the Platinum Series meets the demands of high-end gaming and over-clocking systems, the newest graphic card configurations included. The Platinum Series features a high-tech LLC/full-bridge circuit topology with a unique integrated DC Connector Panel with an embedded Voltage Regulator Module. This design contributes to a near-perfect DC-to-DC conversion that optimizes efficiency by reducing current loss and impedance. For cooling, the Platinum Series incorporates the most advanced version of the Seasonic proprietary S3FC, "Hybrid Silent Fan Control" circuit, which offers three distinct operation modes; fanless, silent and cooling. This updated version enables the power supply to operate in the fanless mode up to an incredible 40% of system load and can be activated or deactivate depending on user preference. As always, the top range Seasonic power supplies are all built with the high grade Sanyo Denki San Ace Silent Fan to deliver a true solution for thermal and noise management. In addition, the Seasonic Platinum Series utilizes top quality components such as gold-plated high current terminals, solid polymer capacitors and made in Japan 105C capacitors to achieve performance and reliability. The Platinum Series meets important safety and environmental standards around the world and has built in protection features such as over power, over current, over voltage, under current, over temperature and short circuit, all to ensure the safe operation of the computer system. The Seasonic Platinum Series is the ultimate power supply series that provides silence and peak performance for efficiency and functionality. It is the ultimate power supply for the high-end and overclocking systems today!
Now that we know what Seasonic expects from this power supply, let's see what we have to look forward to when we purchase the Platinum-1000 in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
