Introduction and Features

The Silencer 750W power supply can deliver up to 60A on a powerful single +12V rail and is backed by PC Power and Cooling’s legendary reputation for reliability and performance. It’s relatively quiet, very efficient and affordable too.

PC Power & Cooling has been in the business of building high-performance PC switching power supplies since 1986 and they have earned one of the best reputations in the industry for performance and reliability.  Today PC Power & Cooling offers several lines of high-quality power supplies ranging in capacity from 300W all the way up to 1kW.  Their Turbo-Cool units are targeted towards high-end applications where clean power and reliability are the top priorities.  PC Power & Cooling’s Silencer power supplies also feature performance and reliability but with an emphasis on quiet operation at an affordable price.

 

In this review we will be taking a detailed look at PC Power & Cooling’s flagship Silencer power supply, the Silencer 750 Quad.  This unit is available with either a traditional black paint job or with a brilliant copper finish.

Establishing an accurate load is critical to testing and evaluating a PC power supply.  PCPerspective’s power supply test bench can place a precise 2,000 watt DC load on the PSU under test.  Each power supply is tested under controlled, real-world conditions up to its maximum rated load (at 40ºC), using both 115 VAC and 240 VAC line voltage.  Our current suite of tests includes:

 

  • DC Load Regulation
  • DC Line Regulation
  • DC Cross-load (unbalanced load)
  • AC Ripple and Noise
  • Power Factor
  • Efficiency
  • Differential Temperature
  • Noise
  • Size and Weight
