Silverstone Zeus 850w ST85ZF Quad SLI PSU

Introduction & Packaging


Around 2 months ago I took a look at the Silverstone Zeus 750w ST75ZF, and was so impressed with the overall quality and stability of the unit that I gave it a total score of 9/10 and the highly regarded 'Editors Choice' Award.

Since then, Silverstone have been hard at work producing an even more powerful 850w unit, which not only has quad +12v rails, but also fully integrated quad PCI-E connectors to boot.

Will this latest unit further strengthen the excellent reputation of the Zeus series? We find out...


Continuing the trend of all previously reviewed Silverstone power supplies, the ST85ZF is packaged in a large black and blue box bearing the Silverstone logo along with a picture of the unit.

Silverstone have updated their packaging slightly with the inclusion of ROHS stamp which came into force on the 1st July 2006. We can also see that the front and top of the packaging offer some basic specifications along with some images of the unit and the rated output of the units rails.

Turn the box around to the side, and we can see some of the 'Special Features' of the Silverstone unit. The ST85ZF boasts 6 SATA connectors, 4 PCI-E connectors, a maximum efficiency of 87% and multiple over-load/volt protection features.

A handy feature of the packaging is the plastic handle on the top of the box, which will certainly make carrying this unit home from the shops a much easier task.

Included in the package are the following items:

- 1x 8-Pin AUX to 4-Pin P4-12v Adapter
- 1x Power cable
- 1x ST85ZF Manual
- 4x ATX Screws
- 1x Silverstone ST85ZF PSU

The unit itself is sandwiched in-between two cardboard layers, each padded out with Styrofoam shapes to protect all corners of the PSU. Also included is a small cardboard box containing the power cord, screws, 8-pin and 4-pin P4-12v converter. The bundle of cables are contained within a bubble-wrap sleeve and tied together with a large cable-tie.

Having a quick flick through the ST85ZF manual I can see that Silverstone have provided detailed information regarding the +12v rail layout of the unit. However, there's an easier way to find out this information, which can be seen on the 'Connectors' page.

"Probably the most power hungry component in a PC is the graphics card. Put 4 of them together for Quad SLI, and you need a seriously beefy PSU. Do Silverstone have the goods?"
