MAG A850GL PCIE5

Overflow with Power

The MAG A850GL PCIE5 power supply provides 80 PLUS Gold-certified power efficiency, ATX 3.0 compatibility, and PCIe 5.0 GPU support, cooled by a 120mm fluid dynamic bearing (FDB) fan for superior performance. Outfitted with a full-bridge LLC DC-to-DC topology, an extra-compact ATX frame, and a fully modular design, this PSU is ideal for spatially-efficient PCs requiring robust, no-nonsense performance.

80 PLUS Gold certified ATX 3.0 compatible & fully modular cable design PCIe 5.0 GPU support (native 16-pin connector) Extra compact (ATX) size Flat black cables with bag 120mm Fluid-Dynamic Bearing (FDB) fan Full Bridge LLC topology & DC-to-DC module Active PFC design (OVP, OCP, OPP, OTP, SCP, UVP)

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.

ATX 3.0 & Fully Modular

ATX 3.0 compatible 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 5.0 GPU Support

Through the native 16-pin (12V2x6) PCIe connector, the PSU can provide up to 600W of power to a PCIe 5.0 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.

Extra Compact Size

A compact 140mm-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.

Flat Black Cables

Flat black modular cables help reduce clutter, improve airflow, and create a cleaner build. Keep the extra cables in an included storage bag.

Fluid-Dynamic Bearing Fan

A 120mm Fluid-Dynamic Bearing (FDB) fan offers reliable cooling performance that balances both noise and temperature output.

Extensive Connectivity

A wide range of connectivity options provides extensive hardware support. Connect and upgrade multiple hard drives, SSDs, graphics cards and other components quickly and easily.

Output Specifications

Robust internals support a wide range of AC inputs, while delivering stable output for high performance components. A full-bridge LLC with DC-to-DC converter includes an active PFC design (OCP, OVP, OPP, OTP, SCP, UVP).
