Cooler Master MWE Gold 1250 V2 ATX 3.1 Fully Modular SMPS

The Cooler Master MWE Gold 1250 V2 ATX 3.1 is a fully modular 1250-watt power supply unit built to meet the demands of high-end desktop systems, including those running the latest RTX 40-series graphics cards. Fully compliant with the ATX 3.1 standard, it ships with a native 12V-2x6 connector that handles the transient power spikes associated with modern high-performance GPUs without the need for adapters. Efficiency sits at the heart of this unit. The 80 PLUS Gold certification means it delivers 90% efficiency at typical load, keeping waste heat low and your electricity bill in check compared to lower-rated alternatives. Japanese capacitors are used throughout the internal design, contributing to long-term reliability even in thermally demanding environments. Cooler Master rates this PSU for continuous operation at up to 50 degrees Celsius ambient temperature, making it a dependable choice for overclocked systems, compact chassis with limited airflow, or enthusiast workstations that run under sustained load. Cooling is handled by a 140mm fluid-dynamic bearing (FDB) fan paired with Cooler Master's Smart Thermal Control (STCM) system. The fan remains off entirely until the unit reaches 40% of its rated output, resulting in a completely silent experience during light workloads and only ramping up when genuinely needed. Fully modular cabling eliminates every unused cable from your build. The included flat black cables simplify routing, reduce airflow obstruction, and give the interior of your case a cleaner appearance. Only attach what your system actually needs.
