Ready for modern GPUs

The MSI MPG A1000G PCIE 5 is a 1000 W ATX 3.1 compatible power supply built for systems that need a native 16-pin 12V-2x6 connector. Its fully modular design and flat cables suit builders who want clean routing and strong 12 V delivery.

Native 16-pin PCIe 5.1 connector

A single 16-pin 12V-2x6 cable ships with the unit so current-generation graphics cards plug in directly without adapters. Six additional 6+2-pin PCIe connectors and twelve SATA power connectors cover the remaining components.

Steady output under load

A 135 mm fluid dynamic bearing fan and Cybenetics Standard++ noise rating keep acoustics low while the 80 PLUS Gold efficiency holds above 90 percent at typical loads. Japanese 105 °C capacitors and full protection circuits maintain stable voltage during extended high-draw sessions.

Questions about this item

What does the 1000 W rating mean for a system with a high-end GPU?

The single +12 V rail can deliver the full 1000 W to the graphics card and other components, with ATX 3.1 support for 2× total power excursion and 3× GPU power excursion.

What does the native 16-pin connector support?

The 12VHPWR connector is PCIe 5.1 ready, allowing direct connection to current and future graphics cards without an adapter.

Will the 150 mm length fit a standard ATX case?

At 150 mm deep the unit matches the compact ATX form factor and fits most mid-tower cases that accept standard-length power supplies.
