MSI MAG A850GL PCIE5 850W Modular Power Supply, Intel ATX12V Version 3.0, 120mm Cooling Fan, 80 Plus Gold Efficiency Rating, 4 x PCIe 6+2-Pin Connectors, 8 x SATA Connectors, White | 306-7ZP8A31-CE0

ATX 3.1 Ready
It has an output port that is compliant with PCIe 5.1 and Intel PSDG(Power Supply Design Guide) ATX 3.1, also the MAG A850GL PCIE5 WHITE power supply can hold up to 2x total power excursion and 3x GPU power excursion.

LEVEL UP YOUR GAME
With native 16 PIN PCIe connector this power supply is ready for Nvidia® GeForce RTX™ 40 Series graphics cards.
It can freely pipe up to 600W of power to PCIe 5.1 graphics cards.

ENERGY EFFICIENCY CERTIFICATION
The efficiency of your power supply directly influences your system’s performance and your power consumption. The 80 PLUS Gold and Cybenetics Platinum certification promises lower energy consumption and higher efficiency.

COMPACT SIZING
Smaller than typical PSUs on the market, this power supply unit that can save space and make it easier to organize cables in the computer case by freeing up more room inside.

Advanced Safety: Dual-Color 16-Pin Connector
The MAG A850GL PCIE5 WHITE introduces a smart solution to one of the most common building errors: improperly seated GPU cables. The native 12V-2x6 (16-pin) cable features a bright yellow connector tip. If you can see the yellow color after plugging it into your graphics card, the cable is not fully seated. This visual safeguard, combined with the refined PCIe 5.1 standard, significantly reduces the risk of thermal issues and ensures a 600W power delivery that is as safe as it is powerful.

Next-Gen Ready: ATX 3.1 & PCIe 5.1
Engineered for the hardware of 2026 and beyond, this PSU is fully updated to the ATX 3.1 specification. It is built to effortlessly handle massive transient power excursions of up to 200% (1700W) of the total power for 100μs. Whether you are running an NVIDIA® GeForce RTX™ 40 series or the latest RTX™ 50 series card, the native 12V-2x6 support means no clunky adapters and a direct, efficient energy path to your most critical components.

Gold Efficiency in a Compact Frame
While many high-wattage power supplies require massive cases, the MAG A850GL features an extra-compact 140mm length. This small footprint frees up precious space in your PSU shroud for cable stowing and improves overall case airflow. Despite its size, it maintains 80 PLUS Gold efficiency (up to 90%) and carries a Cybenetics Gold rating, ensuring that your system runs cool, quiet, and energy-efficient even under heavy gaming or rendering loads.
