MSI MAG A850GL 850 W power supply

The MSI MAG A850GL delivers 850 W of continuous power for desktop computers. It uses a standard 20+4 pin ATX connector and follows the ATX form factor. The unit is built for builders who need reliable energy delivery for modern components. Its black finish suits a wide range of case aesthetics.

Fully modular cable design and PCIe 5.0 support

A fully modular cable set lets you connect only the leads your build requires, reducing clutter inside the chassis. Native PCIe 5.0 12VHPWR connectors are included for current-generation graphics cards. The 5.000 x 12.000 x 9.000 cm dimensions fit standard ATX mounting points. At 2.8400 kg the unit feels solid without being unwieldy.

Check ATX case clearance and GPU connector needs

Verify that your case accepts an ATX power supply of the listed dimensions before ordering. Confirm your graphics card uses the 12VHPWR connector or that the supplied adapters match its input. Ensure the 850 W rating meets the total system draw you have calculated. This unit does not suit builds requiring SFX or TFX form factors.

Questions about this item

What PCIe standard does the 20+4 pin ATX connector support on this 850 W unit?

The 20+4 pin ATX connector delivers up to 850 W to the motherboard and follows the PCIE5 labelling on this model.

Will the 12.000 x 5.000 x 9.000 dimensions fit a standard ATX case?

At 12.000 cm deep, 5.000 cm wide and 9.000 cm high it matches the common ATX PSU envelope, so it fits most mid-tower cases.

Which cables must be connected before the first boot?

Attach the 20+4 pin motherboard cable, the CPU power cable and any GPU cables required; the step often missed is seating the 20+4 pin fully until the latch clicks.
