In a quest to create a PSU that can encompass all the latest and greatest components and beyond effortlessly, SilverStone is introducing the Zeus ST85ZF with 850W of continuous total power at 50?C and 90V AC input. This enormously powerful unit is truly built for the future with the ability to output nearly 99% of its total capacity solely to the +12V rails alone (70A)! Enthusiasts can also rejoice in knowing that ST85ZF’s included connectors are capable of powering four high end PCI-Express graphics cards simultaneously with plenty of headroom for numerous other devices. In addition to packing an impressive array of performance features, the ST85ZF is also a design in finesse with typical working efficiency well above 80% for quiet operation and a size that is impressively compact for power supplies of this class at 180mm deep (same depth as Zeus ST65ZF with 650W). For those who wish to have top-of-the-line industrial power without compromises, the Zeus ST85ZF delivers in spades.
