MSI MPG A850G PCIE5 850W 80 PLUS Gold Modular Power Supply

The MSI MPG A850G PCIE5 is an 850 watt power supply that delivers stable power for gaming rigs, creative workstations, and any build that leans on modern graphics cards. Designed around the ATX 3.0 standard, it arrives with a native 16 pin PCIe 5.0 cable, so RTX 40 Series GPUs and future releases receive the current they need without adapters.

An 80 PLUS Gold efficiency rating means up to 90 percent of the electricity pulled from the wall is converted into usable power, which keeps temperatures down and helps you save on energy costs over time. Inside, 100 percent Japanese capacitors rated to 105 °C and an active power factor correction circuit maintain consistent voltage even when the action on screen pushes every component to its limits.

The fully modular layout lets you attach only the cables required for your build, leaving the rest in the box and clearing space for airflow. A short overall length fits comfortably in most mid tower or compact ATX cases, so routing those cables behind the motherboard tray feels less like a puzzle.

Cooling duties fall to a 135 mm fan that uses a fluid dynamic bearing. The design reduces friction, which means lower noise during light workloads and a longer service life. Built-in safeguards against over-voltage, over-current, over-power, short circuits, and under-voltage add another layer of protection for the hardware you rely on every day.

Whether you are assembling a new flagship gaming system, upgrading an aging power supply for peace of mind, or preparing for next-generation GPUs, the MPG A850G PCIE5 offers the headroom and reliability that make long sessions and demanding workloads feel effortless.
