ATX 3.0 1250 W power supply

The Cooler Master MWE Gold V2 unit delivers 1250 W of continuous power with full ATX 3.0 compatibility. A native 12VHPWR connector supplies up to 600 W to a modern graphics card through a single cable. It is built for high-end desktop systems that demand stable 12 V output.

80 PLUS Gold efficiency and connector headroom

The 80 PLUS Gold rating guarantees at least 90 % efficiency at typical load, reducing waste heat and electricity cost. Three 6+2-pin PCIe connectors and twelve SATA connectors provide generous headroom for multiple drives and add-in cards. The +12 V rail is rated for 104 A, leaving ample reserve for transient spikes before protection circuits engage.

180 mm fully modular design for cable management

At 180 mm long the unit fits standard ATX bays while the fully modular flat cables let builders connect only what the build requires. A 140 mm silent fan with double ball bearings maintains airflow at lower noise levels, and 100 % Japanese capacitors help suppress ripple. The compact 12VHPWR cable frees routing space behind the motherboard tray.
