Introduction
PC Power & Cooling were one of the first companies to ever produce high performance computer power supply units. Two of their product series, the Turbo-Cool and Silencer were released back in 1986 and still exist today, which makes them the oldest high performance power supply series in the history of PC Computing! While most of you probably do not know this (or care to know it!), PC Power & Cooling was the first company to introduce many technologies such as redundant power systems and independently regulated power supply units.
Ever since the company’s birth they have been producing some of the best power supply units that money can buy and you will find they don't sell any "cheap" products. This has earned them a high pedigree reputation within enthusiast circles and many devotee's worried when OCZ bought PC Power & Cooling not long ago, standards might change. It seems that OCZ is not interested in doing that as PC Power & Cooling resumes their business as they always have. Today we will examine their most powerful unit of the Silencer series, the 750W Quad. The PC Power & Cooling 750W Quad unit is being marketed as high performance and reliable, but also ultra-quiet. An ultra quiet unit cooled by a single 80mm fan!
