850 W ATX 3.0 power supply

The MSI MAG A850GL PCIE5 delivers 850 W through a fully modular ATX12V design. It carries 80 PLUS Gold certification and includes a native 12VHPWR connector built for the PCIe 5.0 power standard. A single +12 V rail rated at 70.5 A feeds the entire system.

Builders adding a PCIe 5.0 graphics card

This unit suits builders who need a native 12VHPWR cable for a modern GPU and prefer to run only the cables their build requires. It is not for systems that demand more than 850 W of continuous power or for cases that cannot accept a 150 mm deep power supply.

12VHPWR connector included

The power supply ships with one 12VHPWR connector ready for PCIe 5.0 graphics cards, removing the need for adapter cables. Four additional PCIe 8/6 pin connectors support secondary GPUs or other 12 V devices. Eight SATA and four Molex connectors cover drives and accessories.

Questions about this item

Should I pick this 850 W unit or a lower-wattage model?

Choose the 850 W unit if your build includes a modern GPU that needs the 12VHPWR connector and you want headroom for transient spikes; a lower-wattage model would not include that connector.

What does the 850 W rating mean once the PSU is installed in my PC?

It means the unit can continuously deliver 850 W total across all rails, with the single +12 V rail rated at 70.5 A to handle high-end graphics cards and CPU loads together.

What does the ATX 3.0 label cap in practice?

ATX 3.0 compliance guarantees the native 12VHPWR connector and the power-excursion tolerances required by PCIe 5.0 graphics cards.
