The never-ending demand for higher performance has brought a completely new line of products to the market. With the introduction of the Nvidia SLI technology it became possible to install two graphics cards in a single system. As the technology matured Santa Clara, California-based chip designer decided to double the number of graphics cards in SLI system and the quad SLI concept was born. But quad SLI is more than just four graphics processors in a system!

Apart from theoretically unseen level of performance, quad SLI systems have considerably higher requirements for power supply units’ (PSU) power output. To fulfill the power hunger of four GPUs, Silverstone has introduced its’ Zeus 850W ST85ZF Quad SLI PSU. Overclock3D.Net has taken a close look at this premium class product in order to determine whether Silverstone has succeeded in delivering a true quad SLI system power supply unit.

“The Silverstone Zeus 850w was placed under a load of 646 watts. This counts for a total of 76% of the power supplies rated output. At this load, the power supply required 786 watts from the mains to produce the 646 watts required by our custom made power supply tester,” says the article.

“The Silverstone Zeus 850w has some of the most stable rails on any power supply we’ve tested to date. With less than 0.5% voltage fluctuation on all of the rails, this brings the ST85ZF in direct competition with some of the biggest names in the power supply market,” concludes the author.
