Purpose & Audience

The ASRock CL-750G is a 750 W ATX 3.1 power supply built for desktop PCs that need a native 12V-2x6 connector and 80 Plus Gold efficiency. It targets builders who want PCIe 5.1 readiness without paying for fully modular cabling.

Fit & Alternatives

This unit suits systems drawing up to 750 W where a fixed cable set is acceptable and the 150 mm depth fits the case. Builds requiring fully modular cables, a smaller footprint, or higher wattage should consider other models.

Deciding Specification

The defining spec is the native 12V-2x6 connector combined with ATX 3.1 compliance, which determines compatibility with current-generation graphics cards that use the 12VHPWR interface.
