ATX 3.1 Fully Modular 80 PLUS Gold Certified ATX Power Supply Unit
MWE Gold 1050 V2 ATX 3.1

Connect the Future, connect ATX 3.1

100% ATX 3.1 Compatible

Cooler Master took the initiative and continuously developing our first ATX 3.1 Power Supply lineup. Compliant with ATX 3.1 standard and 12V-2x6 connectors, the MWE Gold 1050/1250 V2 ATX 3.1 can fully support the peak power drawn by the 40 series RTX graphic cards and whole system.

80 PLUS Gold Certified

Efficiency has always been one of the most important factors for users when choosing their power supply unit. While there are a range of efficiency options, 80 PLUS Gold has been the ideal choice for the last several years and continues to be seen as the standard for much of the world. The MWE Gold 1050/1250 V2 ATX 3.1 features 80 PLUS Gold certification, guaranteeing 90% efficiency at typical load.

Quiet Cooling

The MWE Gold 1050/1250 V2 ATX 3.1 has been optimized with an 140mm fan along with an advanced fluid-dynamic bearing (FDB) delivers quiet and effective cooling with a long lifespan. With Smart Thermal Control System (STCM), the fan will not spin until at 40% of rated output power to reduce noise.

Industrial-grade Temperature Resilience

The MWE Gold 1050/1250 V2 ATX 3.1 has improved to operate safely at up to 50 degrees Celsius ambient for high-end computer, overclocking and other high intensity applications. Such a high threshold greatly enhances the performance of your PSU and your system.

Fully Modular Cabling

The fully modular version of the MWE Gold 1050/1250 V2 ATX 3.1 comes with a set of flat black cables that can be customized to each user's individual needs. It's designed for easy cable management that each system only needs to include the cables required. This unused space within the chassis allows for reduced clutter, better airflow and aesthetic, thereby improving your system's overall cooling.
