bequiet! Power Zone 850W CM Power Supply Review

The Power Zone PSUs are designed for the upper end when it comes to power delivery with the base model starting at 650w and finishing out at 1000w.  They all feature an 80plus Bronze rating which helps keep the costs down while still delivering good power.  bequiet! claims that the Power Zone is ideal for High performance PCs including Gaming and Overclocked systems.  The single rail design works well with multi GPU configurations including SLI and Crossfire.

The primary cooling fan is 135mm bequiet! unit with SilentWings technology.  The fan spins at 1500rpm with a 12.9dBA sound rating at full load.  This drops to 11.7dBA under normal operation making the fan virtually silent in a standard desktop.

The Power Zone 850w features a modular cable design that allows you to use only the cables required for your system.  Unlike other modular PSUs you will find a different power plug for each molex type.  PCI Express cables are located across the top and feature a unique 12pin plug design.  Drives are located in the middle and use a flat 5pin plug design and the 12v CPU power are available as a dual P8 connector at the bottom.  Motherboard power is split across two plugs labeled MB

A nice feature that comes with the Power Zone is the dedicated two wire fan connections direct from the PSU.  These fan ports are located along the side of the PSU and deliver 12v constant power.  Sadly no RPM monitoring but they work well for basic case fans and other low wattage devices.
