COOLER MASTER MWE 450 V2 80 Plus Bronze Non Modular ATX 2.0 Power Supply

The Cooler Master MWE 450 V2 (model MPE-4501-ACABW-BIN) is a 450W non-modular ATX power supply built for reliable everyday computing. Carrying the 80 PLUS Bronze EU 230V certification, it delivers a typical efficiency of 88%, which means less energy is wasted as heat during conversion from wall power to DC output for your components. At the heart of its design is a DC-to-DC plus LLC circuit. This topology converts the single +12V rail output down to the 3.3V and 5V levels required by motherboards, storage devices, and peripherals, doing so with low ripple noise and stable regulation. Active Power Factor Correction (Active PFC) keeps the power factor close to unity, reducing reactive power draw from the mains. The unit is cooled by a 120mm HDB (Hydro Dynamic Bearing) fan that adjusts its speed in response to internal temperatures. At light loads (20% rated load) the fan operates at just 11.18 dBA; at 50% load it rises to 17.1 dBA; and at full load it reaches 29.5 dBA — figures that make it well-suited to quiet office and home-office builds. Connectivity covers the essentials for a mid-range system: one ATX 24-pin motherboard connector, one EPS 4+4-pin CPU connector, two PCIe 6+2-pin connectors for a discrete GPU, six SATA connectors, and three peripheral 4-pin (Molex) connectors. All cables are flat and black for easier routing in compact cases. Protections built into the unit include Over-Voltage Protection (OVP), Over-Power Protection (OPP), Short-Circuit Protection (SCP), Under-Voltage Protection (UVP), and Over-Temperature Protection (OTP), with a hold-up time of more than 18 ms at full load on 230 Vac and a rated MTBF exceeding 100,000 hours. The unit is ErP 2014 Lot 3 compliant and holds regulatory approvals including CCC, CE, TÜV-RH, RCM, EAC, cTÜVus, FCC, BSMI, KC, and CB. Cooler Master backs the MWE 450 V2 with a 5-year manufacturer warranty.
