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.

A 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.

100% Japanese Capacitors
The single-rail design is outfitted with high-stability Japanese 105°C capacitors.

A half-bridge LLC with DC-to-DC converter includes an active PFC design (OCP, OVP, OPP, OTP, SCP, UVP protections).

Fluid-Dynamic Bearing Fan
A 135mm Fluid-Dynamic Bearing fan, designed for quiet and stable performance, keeps both noise and temperatures to a minimum.

Premium Cables
The MPG A PCIE5 series come with flat black cables help reduce clutter, improve airflow, and create a cleaner build. Keep the extra cables in an included storage bag.

Stay connected with a broad array of modular cables: ATX x 1, EPS x 2, PCI-e 5.0 x 1, PCI-e x 6, SATA x 8, Molex x 4.

Output Specifications
Robust internals support a wide range of AC inputs, while delivering stable output for high performance components.

A compact 150mm-long and 150mm-wide ATX form factor ensures a comfortable and easy fit in most PC cases. This frees up more space for cable management and airflow to the rest of the system.
