Coolermaster's SilentPro M700W is a quiet, compact PSU (power supply unit) with modular cabling and high efficiency - if you don't push it too far.

Despite its name the Coolermaster SilentPro M700W isn't actually a silent PSU, it is however very quiet under normal loads, with minimal noise from its 135mm fan increasing only when the PSU is pushed to its limits.

Although even when pushed hard, the Coolermaster SilentPro M700W PSU manages to keep the noise down reasonably low. In addition to the quiet fan, Coolermaster has applied a soft anti-vibration strip PSU chassis helping cut down on all major causes of noise.

Rated at 700W, the Coolermaster SilentPro M700W offers a relatively low power specification. However it is able to cope with our full 800W load, albeit with some minor tailing off of voltages.

Under a 350W load, the Coolermaster SilentPro M700W proved to be very efficient: it achieved an efficiency of 84.8 percent. Unfortunately, this efficiency reduced as the power load increased. At its rated 700W, efficiency had reduced to 81.5 percent. While this is still a respectable result, other power supplies maintain higher efficiencies at this power level.

Like BeQuiet's DarkPowerPro 750, the Coolermaster SilentPro M700W uses interchangeable modular cabling. This time provided in flat, ribbon-like strips. There's no colour coding on these cables though save for the grey tint on the PCI-E connectors which helps make it clear which end of the cable is to be plugged into the graphics card and which goes into the PSU itself.

Only a single pair of 6+2pin PCI-Express connectors is supplied with the Coolermaster SilentPro M700W, but if you want to go Quad-SLI we'd recommend going for a more powerful PSU anyway.
