750W ATX 3.0 Power Supply

This fully modular unit delivers 750W of continuous power and meets Intel ATX 3.0 specifications. It targets builders assembling modern PCs that require a native 12VHPWR connector for current-generation graphics cards.

80 PLUS Gold Efficiency and Thermal Profile

The power supply holds an 80 PLUS Gold certification and supports low-load efficiency requirements down to 60% load. A single 120mm fan manages airflow through the 150mm deep chassis while Active PFC and Japanese main electrolytic capacitors contribute to stable operation under typical system loads.

Fully Modular Design with PCIe 5.0 Connector

Full modularity allows only necessary cables to be installed, reducing internal clutter and improving case airflow. The native 16-pin 12VHPWR cable is rated to deliver up to 300W for PCIe 5.0 graphics cards, while the 150mm length fits standard ATX mounting points in compatible enclosures.
