Cooler Master MWE 450 V2 80 Plus Bronze SMPS

The Cooler Master MWE 450 V2 is a 450-watt ATX power supply built around the MWE Bronze series philosophy: deliver consistent, efficient power for everyday desktop builds without unnecessary complexity. Certified to the 80 PLUS Bronze standard at 230V EU, it achieves a typical efficiency of 88%, meaning less wasted energy as heat during normal operation and lower electricity consumption compared to uncertified units. At the core of the MWE 450 V2 is a DC-to-DC plus LLC circuit design. This dual-stage conversion topology takes the single +12V rail output and steps it down to the 3.3V and 5V levels that storage devices, motherboards, and peripherals require — doing so with reduced ripple noise compared to older forward-converter designs. The single +12V rail itself simplifies power delivery by ensuring all connected components draw from one stable source. Cooling is handled by a 120mm Hydraulic Dynamic Bearing (HDB) fan. Unlike sleeve-bearing fans, an HDB fan uses a film of oil to reduce friction, which extends bearing life and keeps noise levels low. The fan is thermally controlled, spinning faster only when internal temperatures demand it. At 20% load the unit measures just 11.18 dBA; at 50% load it rises to 17.1 dBA; at full load the noise ceiling is 29.5 dBA — quiet enough for most home and office environments. The cable set uses flat, flexible black cables, making routing easier inside compact cases and helping preserve airflow by reducing cable bulk. The unit is non-modular, so all cables are permanently attached. Protections include Over Voltage Protection (OVP), Over Power Protection (OPP), Short Circuit Protection (SCP), Under Voltage Protection (UVP), and Over Temperature Protection (OTP), covering the most common failure scenarios in a desktop power chain.
