750 W ATX power supply for gaming builds

The MSI MAG A750GL PCIE5 II is an ATX power supply rated at 750 W continuous output. It targets builders assembling mid-range gaming PCs that need a single, strong +12 V rail and support for multi-GPU SLI configurations. The unit accepts both 120 V and 230 V AC mains input and provides 5 V, 3.3 V, 12 V, -12 V and 5 V standby DC outputs.

750 W capacity with Gold-class headroom

At full load the supply delivers 750 W across its single +12 V rail, giving comfortable headroom for a modern CPU plus one high-end graphics card. Efficiency reaches 90 % at typical loads thanks to 80 PLUS Gold certification, reducing waste heat and electricity cost. The design is not intended for dual-GPU setups that exceed the 750 W budget or for workstations requiring redundant or higher-wattage units.

Active PFC and single-fan cooling

Active power factor correction smooths the input current for cleaner mains draw. A single fan handles thermal management; under normal gaming loads the unit runs within its Gold efficiency envelope, keeping fan speed and audible noise at moderate levels. Power draw from the wall scales with system demand, staying proportional to the 90 % efficiency figure at typical operating points.

Questions about this item

Will this 750 W unit work with a motherboard that still uses a 20+4 pin ATX connector and older 4-pin CPU power?

Yes, the power supply follows the ATX form factor and provides the standard 5 V DC, 3.3 V DC, 12 V DC, -12 V DC and 5 V SB rails that legacy boards require.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

Under load the unit should achieve around 90 percent efficiency; monitoring software or a wall meter will show lower AC draw versus DC output.

Which cables come in the box and what might I need to buy separately for a modern GPU?

The package includes the ATX power supply and its fixed cables; if your graphics card needs a 12VHPWR connector you will need to purchase a compatible cable or adapter separately.
