The MSI MAG A750GL PCIE5 is a 750-watt ATX power supply for desktop PCs. It is fully modular, 80 PLUS Gold certified and designed to the ATX 3.0 standard with PCIe 5 support, which is aimed at modern graphics cards. MSI describes it as a gaming power supply in a compact size.
What 750W means
The wattage is the maximum continuous power the unit can deliver to the whole PC. A system draws what its parts need, not the full wattage, so the supply simply needs enough headroom. A 750W unit typically suits a mid-range to fairly powerful gaming PC, but a graphics card's maker will state the minimum supply it recommends, and that is the figure to check.
ATX 3.0 and PCIe 5
ATX 3.0 is an updated power supply standard. Among other things, it is designed to cope with brief power spikes from modern graphics cards. "PCIE 5" in the name refers to support for the PCIe 5.0 era power connector, the 12-pin (12VHPWR) connector that newer graphics cards use, which lets compatible cards plug in directly rather than through an adapter. Check which connector your graphics card uses and that the cable you need is included with the unit.
80 PLUS Gold
80 PLUS is an efficiency certification. Gold means the power supply meets a higher efficiency level than Bronze or Silver, typically around 87% to 90% at common loads (at 115V). In practice, a more efficient unit wastes less energy as heat, which can mean less fan work.
Fully modular cables
Fully modular means every cable detaches, so you plug in only the ones your build needs. That usually makes the case tidier and the airflow better, and it helps in smaller cases.
Compact size and dimensions
MSI says the unit is compact. The listing gives dimensions of 12.0 x 9.0 x 5.0 inches (which may include packaging) and a weight of 6.1 lb (about 2.8 kg). Check the unit's actual length in the specification against your case's power supply space.
Warranty
MSI lists a 10-year limited warranty, which it says guarantees long-term reliable operation.
Who it suits
It suits builders of gaming or general desktop PCs who want a modern ATX 3.0 supply, and those planning a graphics card that uses the newer connector.
What to check before you buy
- Total power: compare 750W against the recommendations for your processor and graphics card.
- Connectors: confirm you have the cables your parts need, including the graphics card connector.
- Case fit: check length and the ATX form factor against your case.
- Cables: modular cables from other models usually aren't interchangeable.
- Installation: follow the manual and local electrical codes, turn off and unplug the system before working inside, and use a correctly rated outlet.
