MSI MAG A850GL PCIE5 PSU | 850W 80+ Gold Fully Modular ATX 3.1

The MSI MAG A850GL PCIe5 is engineered for the modern era of high-performance computing.

As power demands for graphics cards continue to rise, this PSU stands ready with ATX 3.1 compliance and a dedicated PCIe 5.1 16-pin (12V2x6) connector.

This allows it to safely handle power excursions of up to 1700W (200% of its rated capacity), ensuring your system remains stable even during the most intense gaming spikes.

Efficiency is at the heart of the MAG A850GL.

With an 80 PLUS Gold certification, it operates at up to 90% efficiency, generating less heat and reducing energy consumption.

The fully modular design means you only plug in the cables you need, drastically improving airflow and aesthetics within your chassis.

Cooled by a 120mm Fluid Dynamic Bearing fan, the unit stays whisper-quiet while providing the robust power delivery required for heavy-duty workstations and elite gaming rigs.

What It’s Good For or Fun Facts

• The RTX Specialist: Specifically designed to provide up to 600W of power through a single cable to NVIDIA’s most powerful cards, like the RTX 4090.

• Cable Management Dream: The flat black cables are incredibly flexible, making them much easier to route behind motherboard trays than traditional sleeved cables.

• Compact Power: At only 140mm long, it is more compact than many high-wattage PSUs, leaving more room for cable tucking in smaller ATX cases.

• Fun Fact: The 16-pin connector features a dual-color design. If you can see the yellow part of the connector, it means it’s not plugged in all the way! This simple visual cue helps prevent cable melting issues caused by loose connections.

Good to Knows

• ATX 3.1 Standard: This is the updated version of ATX 3.0, featuring the improved 12V2x6 connector for better thermal performance and safety.

• Safety First: It includes a full suite of industrial protections (OCP, OVP, OPP, OTP, SCP, UVP) to shield your expensive GPU and CPU from electrical anomalies.

• Silence is Golden: The Fluid Dynamic Bearing (FDB) fan is designed to be quieter and last longer than standard sleeve or ball-bearing fans.

• Warranty: Comes with a 7-Year Warranty, giving you long-term peace of mind for your build.
