Built for high-efficiency builds

The MSI MAG A850GL PCIE5 II is an ATX 12V power supply rated for 850 W peak output and 600 W continuous power. It carries an 80 PLUS Gold rating delivering up to 90% efficiency at half load and 87% at full load. The unit suits gamers and workstation users who need stable 12 V, 5 V, 3.3 V and 5 V SB rails.

Modular cabling frees chassis space

A fully modular design with sleeved cables lets you install only the connectors required, saving room and improving airflow inside the case. Standard 24-pin and EPS 4+4-pin motherboard cables are included alongside multiple SATA and PCI Express connectors. Active PFC and a wide 100–240 V input range simplify integration worldwide.

Single fan balances thermals and noise

One fan handles cooling across the 11.8 in x 8.9 in x 5 in enclosure while the Gold-rated efficiency keeps waste heat low at typical loads. The 12 V rail design supports NVIDIA SLI configurations without extra current splitting. Input current draws 10 A at 115 V or 5 A at 230 V, reflecting the unit’s efficient power conversion.
