Power for modern GPUs

The MSI MAG A750GL PCIE5 is an ATX 3.0 compatible power supply rated at 750 W. It targets builders assembling systems around current-generation graphics cards that require the 12VHPWR connector. Full modular cabling keeps the interior tidy by letting you install only the leads you need. The unit carries 80 PLUS Gold certification for efficient AC to DC conversion.

The 12VHPWR connector

A single native 12VHPWR cable delivers up to 450 W on the 12 V rail, satisfying the PCIe 5.0 power specification for high-end GPUs. Three additional PCIe 8/6 pin connectors support secondary cards or older graphics models. Two CPU 8/4 pin cables and one 24/20 pin motherboard cable cover the primary board connections. Eight SATA and four Molex connectors handle drives and accessories.

Thermals and protections

A 120 mm fan provides airflow through the 150 mm deep chassis. The unit operates on 100 to 240 V input at 47 to 63 Hz with a maximum draw of 10 A. Active PFC and a full set of protections — OVP, OCP, OTP, OPP, SCP and UVP — guard components against voltage and current anomalies. The +12 V rail supplies up to 60.2 A under load.

Questions about this item

How much power does the 750 W rating actually deliver to a modern GPU through the 12VHPWR cable?

The 12VHPWR connector is rated for 450 W, so a single PCIe 5.0 graphics card can draw up to that amount from the 750 W total capacity.

What does ATX 3.0 compatibility mean for the 12VHPWR connection in practice?

It guarantees the 12VHPWR cable meets the 450 W specification and handles the transient spikes required by the ATX 3.0 standard.

Will the 150 mm length and 120 mm fan fit in a standard mid-tower case?

At 150 mm long the unit matches the typical ATX clearance of most mid-tower chassis, and the single 120 mm fan exhausts heat out the rear.
