Power supply Cooler Master MWE GOLD 750v3 ATX 3.1 750W 80 PLUS Gold Non-modular, 6x SATA, 4x 6+2 PCIe, 2x 4+4 EPS

Cooler Master MWE GOLD 750v3 ATX 3.1 is a non-modular desktop power supply delivering 750 W total power with 80 PLUS Gold efficiency (approximately 90%). It is designed for ATX systems and provides a stable +12V rail, Active Power Factor Correction (PFC) and overload protection. The unit features a top-mounted 120 mm HDB fan, supports 100–240 V AC input at 50/60 Hz and operates in ambient temperatures from 0 to 50 °C.

Advantages

The power supply offers high energy efficiency with 80 PLUS Gold certification, a robust +12V combined output suitable for modern components, and Active PFC for improved power quality. Its HDB 120 mm fan provides active cooling while maintaining low noise levels. Built to ATX 3.1 specifications with OPP protection and a long MTBF, the unit supports reliable continuous operation.

Suitable for

• Gaming and high-performance desktop PCs
• Workstations requiring stable +12V power
• Systems using multiple PCIe graphics cards or high-power GPUs
• Upgrades where non-modular cabling is acceptable

How to use

Install the PSU in an ATX-compatible case with the fan oriented according to the case airflow design (top-mounted fan). Connect the 24-pin ATX motherboard connector first, then attach EPS connectors to the CPU power socket(s) and PCIe connectors to graphics cards as required. Route non-modular cables to avoid obstructing airflow and secure all connections before powering on the system. Ensure the AC input matches the local mains voltage and use the on/off switch on the unit as needed.

Recommendations

Do not open the PSU housing — risk of electric shock. For reliable operation, maintain adequate case airflow and avoid operating the unit above the specified ambient temperature. Use in systems that require a strong +12V rail and ensure connectors match component requirements.
