MSI MAG A750BN PCIE5 III - 750W Bronze with a 450W 16-pin GPU connector, now ATX 3.1.
The MSI MAG A750BN PCIE5 III is a 750W unit rated 80 PLUS Bronze at up to 85% efficiency, with a 120mm hydraulic bearing fan, active PFC and a 100-240V input range. It is non-modular, measures 140 x 150 x 86mm, and carries a PCIe 5.1 16-pin connector rated up to 450W alongside three PCIe 6+2-pin cables, three SATA and two peripheral connectors. ATX 3.1 certification adds 200% power excursion headroom for modern graphics card transients.
Key Features
-
750W, 80 PLUS Bronze - Up to 85% efficiency, with active PFC and a 100-240V input range.
-
PCIe 5.1 16-pin connector - Rated to 450W, so it feeds a current-generation graphics card without an adapter.
-
ATX 3.1 compliant - 200% power excursion headroom, which is what the spec is there to cover on a GPU that spikes.
-
Non-modular cabling - Fixed cables keep the price down; there is no cable management to do.
-
120mm hydraulic bearing fan - Runs 500-1800 RPM and stays quiet at this power level.
-
Full protection set - OVP, OCP, SCP, OPP and UVP, with a 150,000 hour MTTF.
-
140 x 150 x 86mm - A standard ATX footprint that fits mid-tower cases.

What's in the box
Power supply and fixed cable set (24-pin ATX, 2x CPU 4+4-pin, PCIe 5.1 16-pin, 3x PCIe 6+2-pin, 3x SATA, 2x peripheral).
Who it's for
A budget 750W option for a mid-range build that still uses a 16-pin graphics card - the ATX 3.1 headroom and the 450W connector are the two things that separate this from the older A750BN PCIE5.
