COOLER MASTER MWE 450W 80+ White Non Modular ATX 2.0 Power Supply

The Cooler Master MWE 450 is a non-modular ATX power supply built for budget-conscious PC builders who refuse to compromise on efficiency or reliability. Rated at 450 W continuous output, it carries the 80 PLUS White certification for the 230 V market, delivering a typical efficiency of 85% under normal load conditions — meaning less heat generated inside your chassis and lower energy consumption at the wall. Cooling is handled by a thermally controlled 120 mm HDB (Hydro Dynamic Bearing) fan that spins between 725 RPM and 1,460 RPM. The hydrodynamic bearing design reduces friction and mechanical wear compared to sleeve-bearing fans, contributing to quieter operation over the unit’s rated service life of more than 100,000 hours MTBF. For clean power delivery, the MWE 450 employs Active Power Factor Correction with a typical PFC value above 0.9, paired with a forward-topology circuit. The input accepts 200–260 Vac at 47–63 Hz, making it well-suited for Indian mains conditions. Idle standby power draw is rated under 0.5 W, keeping the unit compliant with ErP 2013 Lot 6 environmental regulations. Protection coverage includes Over Voltage Protection (OVP), Over Power Protection (OPP), Over Temperature Protection (OTP), and Short Circuit Protection (SCP), guarding both the PSU and connected components against common power anomalies. Connectivity covers a wide range of standard PC components without adapters: one 20+4-pin motherboard connector, one 4+4-pin CPU/EPS connector, two 6+2-pin PCIe connectors, six SATA power connectors, three 4-pin peripheral (Molex) connectors, and one 4-pin FDD connector. The unit ships backed by a 5-year manufacturer warranty.
