MSI MAG A1250GL PCIE5 Power Supply

MAG A1250GL PCIE5

Overflow with Power

The MAG A1250GL PCIE5 power supply provides 80 PLUS Gold-certified power efficiency, ATX 3.1 ready, and PCIe 5.1 GPU support, cooled by a 135 mm fluid dynamic bearing (FDB) fan for superior performance. Outfitted with a full-bridge LLC DC-to-DC topology, a compact ATX frame, and a fully modular design, this PSU is ideal for spatially-efficient PCs requiring robust, no-nonsense performance.

80 PLUS Gold

The efficiency of a power supply directly influences system performance and power consumption. An 80 PLUS Gold certified rating means higher efficiency (up to 90%) and reduces internal thermal loading.

MSI MAG A1250GL PCIE5 Power Supply

ATX 3.1 Ready & Fully Modular Cable Design

ATX 3.1 ready power supplies can handle up to 2x total power excursions and 3x GPU power excursions. A fully modular design means that only the connectors required by the build are used. This significantly reduces cable clutter, simplifying the overall build and improving airflow.

PCIe 5.1 GPU Support (Native 16-pin Connector)

Through the native 16-pin (12V-2x6) PCIe connector, the PSU can provide up to 600W of power to a PCIe 5.1 GPU, and includes yellow highlights to help identify a loose connection. Extra GPU power feeds (8-pin VGA connectors) support a broad array of NVIDIA and AMD graphics cards.

Compact Size

A compact 150mm-long and 150mm-wide ATX form factor ensures a comfortable and easy fit in most PC cases. This frees up more space for cable management and airflow to the rest of the system.
