Compact 850 W ATX 3.1 unit
The MSI MAG A850GL PCIE5 is an 850 W ATX 3.1 power supply with 80 PLUS Gold certification. It delivers up to 600 W through a native 12V-2x6 connector for PCIe 5.1 graphics cards. The fully modular design lets builders attach only the cables they need. A 120 mm Fluid Dynamic Bearing fan handles cooling.
Suits PCIe 5.1 GPU builds.
This unit suits systems that need a native 16-pin GPU connector and high efficiency at 850 W. Builders who prefer a fixed-cable layout or who require more than 850 W should look at something else. The compact 140 mm depth fits most standard ATX cases. It operates on 100-240 V input worldwide.
Sustains 850 W with Gold efficiency
Under sustained load the supply maintains its 850 W rating while 80 PLUS Gold efficiency keeps waste heat low. ATX 3.1 compliance allows 2x total power excursions and 3x GPU power excursions for short bursts. The single 120 mm FDB fan speed ramps with temperature to maintain stable output. Active PFC and dual +12 V rails support consistent delivery.
