Cooler Master MWE 450 Watts White V2

Cooler Master MWE 450 White V2 (230V)

Reliable Power. Accessible Efficiency. The Cooler Master MWE 450 White V2 (MPE-4501-ACABW-EU) is a dependable, entry-level ATX power supply designed for budget-conscious builders and standard desktop configurations. Operating on the 230V EU standard, it delivers a guaranteed 85% typical efficiency to reduce energy consumption and heat generation. Utilizing modern DC-to-DC + LLC circuit design, an ultra-quiet 120mm HDB fan, and sleek flat black cables, this non-modular PSU provides safe, stable, and consistent power without the premium price tag.

Key Features

• 80 PLUS Standard 230V EU Certified: Guarantees a minimum typical efficiency of 85% under normal operating conditions. This means less wasted energy, lower electricity costs, and reduced heat output compared to uncertified power supplies.

• DC-to-DC Circuit Design: Modern power supplies need to manage multiple voltage rails securely. The MWE White V2 utilizes a DC-to-DC + LLC forward topology layout to safely and efficiently convert 12V power down to 3V and 5V levels with minimal ripple noise, ensuring stable system operation.

• 120mm HDB Silent Fan: The unit is cooled by a thermally controlled 120mm Hydro-Dynamic Bearing (HDB) fan. It spins smoothly with minimal friction, ensuring incredibly quiet operation during low-intensity tasks while scaling up automatically to keep the PSU cool under heavy loads.

• Flat Black Cables: Building on a budget doesn’t mean your system has to look messy. The MWE 450 White V2 features flat, flexible black cables that are much easier to route through narrow chassis spaces than traditional sleeved cables, allowing for better airflow and a cleaner aesthetic.

• Single +12V Rail: A robust single +12V rail ensures that all system components, particularly your processor and graphics card, receive a steady and reliable feed of power from the same source to avoid uneven load distributions.

• Comprehensive Protection Features: Built-in safeguards protect your system from electrical anomalies. It includes Over Voltage Protection (OVP), Over Power Protection (OPP), Short Circuit Protection (SCP), Under Voltage Protection (UVP), and Over Temperature Protection (OTP).
