MAINGEAR Ignition 850W 80 Plus Gold ATX Fully Modular Power Supply

850W Gold Fully Modular PSU

The MAINGEAR Ignition 850W is an ATX power supply built for high-draw gaming rigs and multi-GPU configurations. It delivers 850 watts through a fully modular cable set, letting builders use only the connections they need. 80 PLUS Gold certification guarantees 91% efficiency or higher at typical loads. Japanese capacitors and a single +12V rail rated at 100 amps support stable output.

Who This Suits And Who Should Look Elsewhere

This unit fits builders running power-hungry graphics cards or multiple GPUs who want clean cable routing and a 10-year warranty. The ECO mode switch stops the 135mm fluid-dynamic-bearing fan at low loads for silent operation. It is not for systems that need more than 850 watts of continuous power. It is not for builds requiring a smaller form factor than standard ATX.

100 Amp Single +12V Rail

A single +12V rail capable of 100 amps supplies the entire 850 watt capacity to CPU and GPU connectors without multi-rail limits. Active PFC exceeds 99% power factor across a 100-240VAC input range. DC-to-DC conversion and active clamp topology keep voltage regulation tight under heavy loads. Comprehensive protection circuits cover over-current, over-voltage, over-power, over-temperature, under-voltage and short-circuit events.
