ATX 3.0 power supply for modern GPUs

The MSI MPG A750G PCIE5 is a 750 W fully modular ATX 3.0 power supply built with 100% Japanese 105°C capacitors and an 80 PLUS Gold efficiency rating. It includes a native 16-pin 12VHPWR cable for PCIe 5.0 graphics cards and uses an LLC half-bridge topology with DC-DC modules. A single 135 mm fan runs at Cybenetics A noise levels.

Best for builds with PCIe 5.0 graphics cards

This unit suits builders pairing a 4070-class or similar GPU that uses the 12VHPWR connector and who want flat, fully modular cables for cleaner routing. It is not for systems that need more than 750 W of continuous power or for older platforms that lack ATX 3.0 excursion-handling support.

Native 16-pin 12VHPWR connector included

The power supply ships with a 16-pin 12VHPWR cable so you can connect a PCIe 5.0 graphics card directly without an adapter. This single specification decides whether the unit matches your GPU and build plans.

Questions about this item

What case clearance does the 150 mm long ATX 3.0 unit require?

The power supply measures 150 mm in length, so the chassis must provide at least that much depth from the mounting face to any drive cage or motherboard tray obstruction.

How is the native 16 pin 12VHPWR cable connected to a PCIe 5.0 graphics card without an adapter?

Plug the supplied 12VHPWR cable directly into the card's 16 pin receptacle, ensuring the latch engages fully; the PSU side uses a dedicated PCIe 5.0 port on the modular panel.

When should the 135 mm fan be cleaned to maintain the Cybenetics A noise rating?

Remove dust from the fan blades and intake grill every six to twelve months, or whenever audible noise increases, using compressed air while the unit is powered off and unplugged.
