Power Supply with 80 Plus Platinum Efficiency & Powerful 70 A Rail

The Seasonic Prime 850 W Platinum is truly a monster among power supplies, delivering 850 Watts of total output to high-end PCs, more than enough even with two graphics cards in a CrossFireX or SLI setup. The powerful 12V rail delivers a full 70 A of power. Despite these impressive specifications, the Seasonic Prime 850 W Platinum is extremely efficient due to the use of high quality capacitors. This 80 Plus Platinum-certified power supply achieves an efficiency of up to 94% at 50% load.

The fact that all cables can be connected individually ensures cable management is a breeze - a must with such an extensive range of connectivity options! Finally, in addition to one 24-pin and two 4+4-pin cables, there are also six 6+2-pin PCIe connectors as well as ten SATA- and five 4-Pin Molex connectors. This means that even enthusiast boards and server boards can be installed. The cables are very flat and easy to guide.

It almost goes without saying that the Seasonic Prime 850 W Platinum has all the necessary protective circuits that modern high-end power supplies offer. However, should there be an issue with the power supply, no problem, because Seasonic even offers a twelve-year manufacturer's warranty on this exceptional product!
