Overview

This fully modular 750-watt ATX 3.1 power supply delivers 80 PLUS Platinum efficiency and includes a native 12V-2x6 cable for modern graphics cards. It suits high-performance gaming or workstation builds.

Design and Build

The unit measures 150mm wide, 86mm tall, and 140mm deep with a black finish. A 120mm PWM fan uses a fluid dynamic bearing and a switchable hybrid mode that stops the fan at low loads for silent operation.

Performance and Standards

ATX 3.1 compliance and PCIe 5.1 readiness support modern GPUs. The single +12V rail provides 62.5A for 750W total. 80 PLUS Platinum certification guarantees 89% to 91% typical efficiency across loads.

Cable Connectivity

Fully modular sockets include a 24+4-pin SENSE motherboard connector, five 8-pin CPU/PCIe ports, four 6-pin peripheral ports, and one dedicated 12V-2x6 GPU port. Included cables cover motherboard, two CPU, four PCIe (6+2-pin), one 12V-2x6, three SATA chains, and one Molex/floppy chain.

Protection and Reliability

Protection circuits cover overcurrent, overpower, overtemperature, short circuit, and undervoltage conditions. The hybrid fan mode reduces bearing wear to extend unit lifespan. A five-year warranty backs the product.
