COOLER MASTER MWE 1250W V2 80+ Gold Fully Modular ATX 3.1 Power Supply ( 1250W )

The Cooler Master MWE Gold 1250W V2 ATX 3.1 is a fully modular power supply unit designed for high-end desktop builds, including systems running the latest RTX 40-series graphics cards. Rated at 1250 watts of continuous output, it carries 80 Plus Gold certification, which corresponds to a minimum of 90% efficiency at typical load, helping to keep heat output and energy costs in check during extended sessions. One of the most notable aspects of this unit is its ATX 3.1 compliance. This updated standard introduces the 12V-2×6 connector, replacing the older PCIe connectors for high-power GPU connectivity. This means the MWE Gold 1250 V2 can deliver the full transient power spikes demanded by modern graphics cards without relying on adapter cables, reducing potential points of failure and simplifying cable routing. Cooling is handled by a 140mm fluid dynamic bearing (FDB) fan, paired with Cooler Master’s Smart Thermal Control system. The fan remains stationary until the unit reaches 40% of its rated output load, keeping the system virtually silent during lighter workloads such as browsing or video playback. Once load increases, the fan ramps up gradually for effective thermal management. The fully modular cable design means every cable — including the ATX motherboard and CPU power leads — can be disconnected when not in use. Only the cables your build actually needs are installed, reducing clutter inside the chassis, improving airflow, and making future upgrades or maintenance significantly easier. High-quality Japanese capacitors are used throughout, and the unit is rated to operate at ambient temperatures of up to 50 degrees Celsius, making it suitable for thermally demanding environments such as overclocked systems or inadequately ventilated cases.
