Seven hundred and fifty watts, that?s the total amount of power this unit can deliver, Silverstone has partnered with
Etasis to bring a silent, powerful and affordable PSU to the masses. But I hear you say: with Intel releasing Core 2 and Pentium D ?power guzzlers? leaving the scene, do we even needs such high rated PSU in our systems?
While you are correct that on the CPU front we are being given a break, it?s now the video cards which take the top spot, with multi GPU configurations and high power chips like the ones on ATI?s X1900 series the need for a powerful PSU is still here. And once you start overclocking the total power consumed might be quite an eye opener.
Silverstone ST75ZF ?Zeus? 750W Power Supply
(Photo from Silverstone site - our box was in sligthly less presentable state)The Zeus 750W unit from Silverstone boasts promising specifications, is quite light weight, features only a single 80mm low-noise fan and comes painted in black.

Rated at minimum 24dBA it?s most promising, we?ll have to find out if the maximum rating is not 60dBA (let?s hope not).
