Early in the millennium, there was a TV channel called ZDTV (which changed to TechTV in late 2000). I had recently discovered the world of enthusiast computing and a television channel made for geeks by geeks was pretty awesome. Probably the most popular show on this channel was a computer and gadget based show called “The Screen Savers” (which former OCIA.net owner Josh Forhman was featured on back in 2001).

Hosted by geeks Leo Laporte and Patrick Norton, the show covered a broad swath of the enthusiast PC world including gaming, modding, hacking (Digg founder and tea aficionado Kevin Rose started out as a guest hacker, then the resident hacker, and eventually became a co-host), programming, etc. Most shows included guests from the PC world, my favorite was a guy that was a Photoshop guru. They even had a call-in portion of the show where the show staff helped people with PC problems and gave advice. Laporte left the show for a full time call-in PC help show show named “Call for Help”.

It was during the call-in section of the show that a caller asked for advice in purchasing a power supply. The consensus of the cast was that the best power supply was by PC Power & Cooling, with no mention of any other brand of PSU, including a recently purchased Antec that I was pretty proud of. I did a little research into PC P&C and understood why they recommended it. At that time there was only one place to get a PC Power & Cooling PSU – directly from the factory.

That was about a decade ago, and though I have since owned at least 25 different power supplies, with several of them considered some of the best on the market, deep in the recesses of my consciousness, I've always wanted to try a PC Power and Cooling PSU. When the company was purchased by OCZ Technologies in 2007 I thought that maybe my chances of getting one had increased. That opportunity was realized and here I am with a PC Power & Cooling Silencer MkII 750 Watt power supply for evaluation.

PC Power & Cooling opened a factory in a warehouse just outside of San Diego, CA in 1985. They started out building custom fans for cooling computers in silence. The following year they came out with their first power supplies, the first high performance and ultra quiet PSUs in the PC industry. In the following years they introduced many innovative PC industry firsts: the first CPU cooler, the first PC heat alarm, the first independently-regulated PC power supply, the first redundant power system, the first nVidia-certified SLI power supply, the first One Kilowatt computer power supply, and the first power supply with its own certified test report (Turbo-Cool 1KW). When PC P&C was purchased by OCZ Technologies, rather than disassemble the company, OCZ added some much needed working capital to help PC Power & Cooling do what they do even better.

Today I will be looking at what is the latest version of PC Power & Cooling's most popular power supply, the 750 watt Silencer Mk II. It is 80Plus Silver rated with 88% efficiency, SLI Certified, has a full seven year warranty, and carries with it the reputation of PC Power & Cooling.
