Overview

A 750-watt semi-modular power supply built for reliable performance and clean cable routing. It suits entry-level builders and gamers who want modern connectivity and quiet operation.

Design and Cable Management

The unit uses a semi-modular layout where the 24-pin ATX and dual CPU-EPS cables are fixed. PCIe 6+2, 12V-2x6, and SATA cables attach only when needed. Velcro straps on three sides of the housing help bundle excess wiring for better airflow.

Performance and Standards

Rated at 750 watts with 649.2 watts available on the 12V rails, the PSU meets 80 PLUS Bronze efficiency. It complies with ATX 3.1 and PCIe 5.1 specifications, supporting current and next-generation graphics cards. High-quality electrolytic capacitors maintain stability up to 40°C.

Cooling and Noise

A 135mm hydro-dynamic bearing fan replaces the typical 120mm unit, moving more air at lower speeds. Under load the fan reaches 1,600 RPM while producing 40.1 dB(A). The larger diameter keeps temperatures steady even during extended heavy use.

Connectors Included

Two 8-pin CPU connectors, two 8-pin PCIe, two 6+2-pin PCIe, one 12V-2x6 with adapter, and five SATA connectors are provided. Cable lengths range from 100mm for the 12V-2x6 and PCIe leads up to 850mm for SATA, with the 24-pin at 600mm and CPU at 650mm.
