MSI MAG A850GL PCIE5 850W ATX 3.1 & PCIe 5.1 Ready Fully Modular Gaming Power Supply, 80 PLUS Gold Certified, Native 16-pin 12V-2×6 Connector, Flat Cables, Compact 140 × 150 × 86 mm Chassis

The MSI MAG A850GL PCIE5 850W (Model 306-7ZP8A18-CE0) is designed to power today’s cutting-edge gaming and creator systems while remaining future-proof for tomorrow’s next-generation hardware. With an 850 W continuous output rating, and full compliance with ATX 3.1 and PCIe 5.1 standards, this power supply is ready for the most demanding setups, including high-end graphics cards, multi-GPU configurations, VR rigs, and AI/ML creators looking for reliable performance.

Built around a high-efficiency platform, the MAG A850GL delivers 80 PLUS Gold certification—supporting up to approximately 90% efficiency under typical loads—reducing wasted energy and heat output. The fully modular flat-cable design clears clutter, improves airflow, and provides clean aesthetics inside your chassis. Coupled with a compact chassis measuring just 140mm width, 150mm length and 86mm height, this unit fits easily into many mid-tower systems without sacrificing features or clearance.

One of the standout features is the native 16-pin (12V-2×6) PCIe connector, tailored for modern GPUs that demand higher-current delivery—MSI specifies support up to 600W GPU draw on this connector. This forward-looking design eliminates the need for adapters and ensures compatibility with next-gen GPUs. Additional connectors include four standard 6+2 PCIe ports, eight SATA, four 4-pin peripheral, one FDD, one 20+4 ATX, and two 4+4 EPS CPU connectors, giving builders flexibility for storage, peripherals and workstation expansions.

Reliability is emphasised with full protection: Over-Current Protection (OCP), Over-Voltage Protection (OVP), Over-Power Protection (OPP), Over-Temperature Protection (OTP), Short-Circuit Protection (SCP) and Under-Voltage Protection (UVP). The unit also supports a power excursion of up to 1700W (200% of rated power) for 100 micro-seconds, catering to modern GPU/CPU transient spikes during gaming or load transitions. This ensures stable and safe operation even under heavy and sudden load bursts.

Cooling is handled via a 120mm fluid-dynamic bearing fan designed for quiet operation and longevity. The combination of efficient design, premium components and robust protection ensures that this unit is suitable for high-performance builds, overclocked systems and creators who demand stable power under heavy workloads.

For builders, the MAG A850GL offers a balanced package of performance, future-proof features and practical design. Whether you’re deploying an RTX 40/50-series gaming machine, streaming rig, AI workstation or storage-heavy editing workstation, this PSU delivers not only the wattage but the protocols and connectors required to support advanced components. Coupled with MSI’s standard warranty and build quality, you’re getting a power supply designed to grow with your system over time.
