Cooler Master MWE 400 White 230V - V2 Power Supply Unit - UK Plug 80 Plus 230V EU Standard rated, the MWE White 230V - V2 Series outclass generic competitors in the 80 Plus Bronze range under medium loading. The 120 mm fan with superior hydro-dynamic bearings (HDB) keeps noise to a minimum (<30.4 dBA at 1500 RPM max.) with real time adjustment to variable loading demands. Supports Intel PC motherboard low-power states to protect against complete PSU hardware failure. Internal DC-to-DC circuit with LLC converts 12V power to 3V and 5V levels with minimal ripple noise. Single +12V rail ensures all system components receive a constant power feed from the same source across all connections. Flat black cables take up less space and are highly flexible - ideal for smaller cases and preserving internal airflow. Standard limited manufacturing coverage 3 years from the date of purchase. MEDIUM LOADING: 85% EFFICIENCY Performing well above the 80 Plus 230 V EU energy efficiency benchmarks, the MWE 400 White 230V - V2 even outclasses competitors in the 80 Plus Bronze range under medium loading. QUIET HDD FAN The 120 mm housing fan employs superior Hydro-Dynamic Bearings (HDB) which help keep noise to a minimum (<30.4 dBA at 1500 RPM max.) as the speed automatically adjusts to variable loading demands.

Internally, the DC-to-DC circuit with LLC converts 12V power to 3V and 5V levels with minimal ripple noise or energy loss. SINGLE +12V RAIL Ensures all system components receive a constant power feed from the same source across all connections. COMPACT CABLING LOW NOISE Review: Decent PSU at a very good price. - Decent weight to PSU and relatively quiet fan under normal use. Cables are also of the flat variety which is handy for cable management. Review: Cooler Master MWE 400W PSU - It works perfectly, I have never heard the fan and I have put it through some heavy loads. The only thing I can't advise is not using a 160 watt gpu as it will only draw 139 out of 160 watts that is needs. ## Features - 400 WATTS AT EXCEPTIONAL EFFICIENCY - Performing well above the 80 Plus 230 V EU energy efficiency benchmarks, the MWE 400 White 230V - V2 even outclasses generic competitors in the 80 Plus Bronze range under medium loading (see technical review chart for comparison). - QUIET HDD FAN - The 120 mm housing fan employs superior hydro-dynamic bearings (HDB) which help keep noise to a minimum (<30.4 dBA at 1500 RPM max.) as the speed automatically adjusts in real time to variable loading demands. - STABLE & SMOOTH - Fully supports Intel PC motherboard low-power states to better protect against the risk of a complete PSU hardware failure.
