Silverstone ST85ZF Zeus 850w Power Supply

87% Efficient PSU

 

Quad +12V rail for superior performance (70A combined)
Quad PCI-E 6pin connectors
Industrial class components
Support for ATX 12V 2.2 & EPS12V
Active PFC
Efficiency greater than 80% (max. 87%)
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.
