Cooler Master MWE Gold 1250W V2 ATX 3.1 Power Supply Unit

The Cooler Master MWE Gold 1250W V2 ATX 3.1 delivers reliable, efficient power for high-performance gaming systems and workstations. This fully modular power supply features 80 PLUS Gold certification, ensuring 90% efficiency at typical load while reducing energy costs and heat output.

ATX 3.1 Standard Compliance

Built to meet the latest ATX 3.1 specifications, this PSU includes a native 12V-2x6 connector that fully supports the peak power demands of NVIDIA RTX 40 series graphics cards and other high-end components. The ATX 3.1 standard ensures compatibility with next-generation hardware while maintaining stable power delivery during demanding workloads.

80 PLUS Gold Efficiency

Certified 80 PLUS Gold with up to 90% efficiency at typical load, the MWE Gold 1250W V2 reduces wasted energy and generates less heat compared to lower-rated power supplies. High-quality Japanese capacitors ensure consistent performance and longevity, even under sustained heavy loads.

Advanced Cooling System

The 140mm fluid-dynamic bearing (FDB) fan provides quiet, effective cooling with extended lifespan. Smart Thermal Control System (STCM) keeps the fan idle until the PSU reaches 40% load, minimizing noise during light usage. The fan curve is optimized for 25°C ambient temperature with load-responsive thermal management.

Industrial-Grade Temperature Performance

Engineered to operate safely at ambient temperatures up to 50°C, this power supply handles high-intensity applications, overclocking, and demanding workloads without thermal throttling. This temperature resilience ensures stable performance in warm environments or compact cases with restricted airflow.

Fully Modular Cable Design

The fully modular configuration includes flat black cables that connect only when needed. This design simplifies cable management, reduces clutter inside your chassis, and improves airflow for better overall system cooling. Customize your cable layout to match your specific build requirements.

Comprehensive Protection Features

Multiple safety mechanisms protect your components: Over Voltage Protection (OVP), Over Power Protection (OPP), Short Circuit Protection (SCP), Over Current Protection (OCP), Under Voltage Protection (UVP), Over Temperature Protection (OTP), and Inrush Protection. These safeguards ensure reliable operation and component longevity.

Complete Connectivity

Equipped with 1x ATX 24-pin, 1x EPS 4+4 pin, 1x EPS 8-pin, 12x SATA, 4x Peripheral 4-pin, 3x PCI-e 6+2 pin, and 1x 12V-2x6 connector. This comprehensive selection supports multi-GPU configurations, extensive storage arrays, and numerous peripherals.
