PC POWER COOLING Silencer MKIII 1200W review

1. Features, specs

We have in our labs the Silencer Mk III 1200W (PPC MK3S1200) power supply unit from PC Power & Cooling, an OCZ Group company. The power supply has been designed to meet the power demands of game rigs, by providing a massive 1200 wattage along with high efficiency and convenience and flexibility through a modular cable design.

The Mk III 1200W is the Silencer Series’ most powerful solution yet. It meets the 80 Plus Platinum certified rating and promises an over 92% efficiency at typical workloads. The Mk III combines a single +12V rail, high-quality components including 100% Japanese 105°C capacitors, and protection circuits while maintaining continuous, stable output at a 50°C ambient temperature.

A new feature on this latest model is the Dual Thermal Control System, an operation that allows the user to switch the PSU between normal and silent mode seamlessly, working in conjunction with the load and temperature controlled 140mm fan for quiet operation.

The Silencer Mk III 1200W Series comes backed with PC Power’s 7 year warranty and retails for $300.
