Product Description

MSI MAG A850GL 850W Full Modular 80+ Gold PCIe 5.0 Compact Power Supply


The MAG A850GL PCIE5 power supply offers 80 PLUS Gold-certified energy efficiency, ATX 3.0 compatibility, PCIe 5.0 GPU support (up to 600W), and a Fluid Dynamic Bearing (FDB) fan for quiet and stable performance.


Being ATX 3.0 compatible, the MAG A850GL PCIE5 power supply can handle up to 2x total power excursions and 3x GPU power excursions. A fully modular design means that only the connectors required for by the build are used. This significantly reduces cable clutter, simplifies the overall build and improving airflow.


The MSI MAG A850GL PCIE5 power supply features extra GPU power feeds (4 x 8-pin VGA connectors) to support a broad array of NVIDIA and AMD graphics cards. Alternatively, through the native 16-pin PCIe connector, the PSU can provide up to 600W of power to a PCIe 5.0 GPU.


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.


Developed for quiet and stable operation, a 120 mm Fluid-Dynamic Bearing achieves a good balance between cooling performance and noise level.


A compact 140 mm-long and 150 mm-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.


The flat black cables allow for improved cable management and provide more space for airflow. Because of its fully modular design, only the necessary cables need to be plugged in and the rest can be stored in the supplied cable bag.
