Silverstone Zeus 850w ST85ZF Quad SLI PSU
Introduction & Packaging
Published: 1st August 2006 | Source: Silverstone | Price: |
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...
Packaging
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.

Now that is a kick ass power supply! Sign me up for one of those when I build my next rig, dizamn... Nice review and nice PSU.
OMG, how sexy is that
Plenty of stable power, great looks and finished to the last detail; boy Silverstone are making some awesome gear. This is one PSU that I'm seriously looking at purchasing when it becomes available here in Aus (younger sibling only available atm, as far as I can see). Great review Jim as usual

I love its native support for quad SLI, as useless as it is
Someday quad SLI will probably be the "norm" for gamers *sigh* Thus the reason I decided to step away from the PC scene a bit, too damn spensive I say!!
