Cooler Master MWE Gold V3 550W ATX 3.1 Power Supply

The MWE Gold V3 represents the evolutionary upgrade to Cooler Master's G Gold PSU series, now with full ATX 3.1 compliance. This 550W fully wired power supply delivers 80 Plus Gold efficiency, achieving over 90% efficiency at typical loads during 115V testing. Built with DC-to-DC + LLC circuit design and equipped with a Hydro Dynamic Bearing fan, this unit provides reliable performance for modern gaming and workstation builds.

ATX 3.1 Compliance for Next-Gen GPUs

Full ATX 3.1 support enables peak power delivery up to 1.5 times the rated 550W maximum wattage, making this PSU compatible with power-demanding 40 series GPUs and future graphics cards. The single +12V rail design ensures consistent power output across all connected cables, while two EPS 8-pin/4+4 pin connectors provide universal compatibility with current-generation motherboards.

Advanced Cooling and Temperature Resilience

The 120mm Hydro Dynamic Bearing fan operates at up to 1800 RPM, delivering quiet and effective cooling throughout the unit's lifespan. With a maximum operating temperature of 40°C, this power supply maintains stable performance during overclocking sessions and high-intensity applications. The HDB fan technology reduces noise while extending the unit's MTBF to 100,000 hours.

Comprehensive Connectivity

This fully wired configuration includes embossed cables with improved texture for better grip and aesthetics. Connector layout includes: 1x ATX 24-pin (500mm), 2x EPS 8-pin/4+4 pin (550+120mm), 2x PCIe 6+2 pin (550+120mm), 6x SATA (2x 400+150+150mm), and 3x Peripheral 4-pin (1x 400+150+150mm). Active PFC and 100-240V AC input provide worldwide compatibility.

Protection and Reliability

The DC-to-DC circuit design delivers stable voltage regulation to all connected components. Multiple protection mechanisms include UVP (Under Voltage Protection), OVP (Over Voltage Protection), OPP (Over Power Protection), OTP (Over Temperature Protection), SCP (Short Circuit Protection), and OCP (Over Current Protection). Backed by a 5-year limited manufacturing warranty from date of purchase.
