80 PLUS Gold

The efficiency of a power supply directly influences system performance and power consumption.

An 80 PLUS Gold certified rating means higher efficiency (up to 90%) and reduces internal thermal loading.

ATX 3.0 Ready, Full Modular

Being ATX 3.0 compatible, MPG A PCIE5 power supplies can handle up to 2x total power excursions and 3x GPU power excursions.

fully modular design means that only the connectors required by the build are used. This significantly reduces cable clutter, simplifying the overall build and improving airflow.

PCIe 5.0 GPU Supported

MSI MPG A PCIE5 PSUs feature extra GPU power feeds (3 x 8-pin VGA connectors) to support a broad array of NVIDIA and AMD graphics cards.

Alternatively, through the native 16-pin (12VHPWR) PCIe connector, the PSU can provide up to 600W of power to a PCIe 5.0 GPU.

Zero RPM Mode

The 0% RPM Mode turns off the fan whenever loading is under 40% TDP to minimize power usage and noise. The default mode can be turned off via a “Zero Fan” button.
