PC POWER COOLING Silencer MKIII 750W review
1. Features
We have in our labs the Silencer Mk III 750W (PPC MK3S750) power supply unit from PC Power & Cooling, an OCZ Group company. The 750W version was added to the company's Silencer Mk III Power Supply Series at CES in January.
The power supply has been designed to meet the power demands of professional and enthusiast users, by providing a 750 wattage along with high efficiency and convenience and flexibility through a modular cable design.
The Silencer Mk III 750W meets the stringent 80 Plus Gold certification for energy-efficiency ratings and support over 90 percent efficiency under typical workloads. Featuring its popular Dual Thermal Control System (an operation that allows either PSU model to be switched between normal and silent modes), the Silencer Mk III works in conjunction with the load and temperature controlled fan for quiet operation. Additionally, the PSU combines a single +12V rail, premium components (including 100 percent Japanese 105°C capacitors), protection circuitries, continuous stable output at a 50°C ambient temperature, and heavy-duty chrome finish metallic cable connectors to provide excellent conductivity and lower resistance.
The Silencer Mk III 750W is backed by a 7 year warranty and retails for $140.
