  • Exceptionally high efficiency thanks to 80 Plus Gold certification

Power Supply with 80 Plus Gold Efficiency and Powerful 45 A Single Rail

The Seasonic Prime Ultra 550 W Gold is a giant in performance terms, supplying up to 550 Watts of power it is capable of powering even high-end PCs, including those with two graphics cards in a CrossFireX- or SLI setup. The powerful 12 Volt rail delivers 45 A. In spite of these inpressive specifications, the Seasonic Prime 550 W Gold is also efficiently designed, something resulting from the highest-quality components e.g. capacitors. This is how it achieved the 80 Plus Gold certification that guarantees efficiency of up to 90% at 50% load.

The fact that all cables can be connected individually ensures an extremely neat and tidy look - a must-have if you plan to install a lot of high-end hardware. Finally, in addition to the 24-pin- and two 4+4-pincables among others there are also two 6+2-pin PCIe connectors along with six SATA- and three 4-pin Molex connectors and a floppy connector. This means that even enthusiast-level and server class motherboards can be installed. As you might expect with such high-performance components, there will also be a lot of cabling: Fortunately Seasonic has your back again and has made the cables very flat and easy to guide to where they need to go.

It almost goes without saying that the Seasonic Prime 550 W Gold has all the necessary protective circuits that modern high-end power supplies must of course offer. However, should the PSU suffer a fault, no problem: Seasonic gives a twelve-year manufacturer's warranty on this exceptional product!
