Efficient 750W Power Delivery

The MSI MAG A750GN PCIE5 is a 750W power supply designed for modern gaming PCs. Its 80 PLUS Gold rating delivers efficiency of up to 90%, while Active PFC and a single +12V rail support stable power delivery.

Ready for Modern Graphics Cards

ATX 3.1 readiness and a native 450W PCIe 5.1 16-pin connector support compatible NVIDIA GeForce RTX 40 and 50 Series graphics cards. The PSU can handle total power excursions of up to twice its rated output and GPU power excursions of up to three times the graphics card’s rated power.

Two additional PCIe 6+2-pin connectors provide flexibility for graphics cards that use conventional power connections.

Cooling and Construction

A 120mm sleeve-bearing fan balances cooling with low-noise operation, remaining below 20dBA at 70% load under MSI’s stated test conditions. The full-bridge topology, DC-to-DC module and 105°C-rated main capacitor are designed to provide efficient, stable operation.

Built-In Protection

Integrated overcurrent, overvoltage, overpower, overtemperature and short-circuit protections help safeguard connected components. Flexible black flat cables simplify routing inside compatible cases.
