Silverstone Zeus 1200W: Designed for the Power Hungry

Package and Appearance
The package is typical Silverstone. All the important features are clearly visible on the black and blue box. The power supply lies between two sheets of plastic foam with the many cables tucked around it. Also in the box are screws, a manual, cables ties, a power cord, and a bag in which unused cables can be stored.
Two features of this power supply normally don't fit well with a 1200W design. One is the 80mm fan and the second one is the cable management system. Normally an 80mm fan needs plenty of ventilation at the front so that air will properly flow through the internals and provide adequate cooling. Those openings make it difficult to place the connectors for cable management. The Antec Truepower Quattro that we reviewed last year provided a good solution. Half of the front section was covered with the jacks of the cable management and the other half was perforated to let air inside of the housing.
Silverstone made things a little more difficult since they wanted all of the cables to be removable; that results in more jacks and therefore requires more space. They accomplished their goal by placing two rows of holes all around the housing to work as air intakes. The cable management is at the front and doesn't affect the airflow, and Silverstone manages to stick with a 80mm fan. The power supply comes in the usual black color as we see from Silverstone.

Electrical work is expressed in terms of POWER. DC power uses Watts as the unit. Watts = Voltage times Amps. Thus with perfect efficiency 120 watts can be obtained EITHER with 12 volts at a 10 amp load, or 120 volts at a 1 amp load.Thus 12 volts running 100 amps = 1200 Watts. 120 volts running just 10 amps also equals 1200 watts. The difference in power available versus power drawn from the wall is loss of efficiency, generated mostly as heat.
According to Ohms law current (amps) = voltage divided by resistance. Thus 10 amps would be drawn by 120 volts across 12 Ohms, or 12 volts across 1.2 Ohms.

Ahhhhhh, thank you! At one time I knew Ohm's law, but had forgotten the role voltage played!RamarC - Monday, July 7, 2008 - link
will other manufacturers start using the deity naming scheme? are the Corsair Ra and OCZ Shiva next?yacoub - Monday, July 7, 2008 - link
No dude, Zeus is purposeful: He carries a lightning bolt. See the line Samuel L. Jackson delivers in Die Hard 3.Merman - Monday, July 7, 2008 - link
[quote]The quality of each rail is also surprisingly good. Ripple on the lower voltage rails doesn't reach higher than 4mV, and the 12V rails don't reach more than 12mV even with full load. At lower loads, the 12V rails are also around 4 to 8mV which is a very good result.[/quote]Finally talking about power quality again.
Considering the ATX12V specification is a maximum of 120mV peak to peak is this result not outstanding and probably the best available on the market???
Or is there a discrepancy in measurment with ATX specifications???
It would be nice to compare ripple results from this site with the other top power supply review sites.
If for some reason this is not possible please educate us rather than take the position that most don't understand this subject nor care.

I still find those ripple/noise generation findings a bit on the fantastic side. If they are what are represented, this means it blows PCP&C's best out of the water for controlling ripple and noise generation at full output.But, while Impervio is good at power supply manufacture, and this was made by Impervio, not Enhance as stated in the article, I sincerely doubt it actually measured only 12mV at full load and only 4-8mV otherwise on the +12V rails. Those figures are just too damned fantastic to be real. And to call them only "good"? They should have been labeled "The best" or "fantasy".

Impervio doesnt have own production facility and produces at Enhance instead.Christoph Katzer - Tuesday, July 8, 2008 - link
This unit is made by IS Quasar. A factory with several robotic assemblers in Taiwan. Almost all of the Silverstone models we reviewed so far came from there.Adamantine - Monday, July 7, 2008 - link
Or could label them as "godly".coolsam2 - Monday, July 7, 2008 - link
