1200W ATX power supply for high-output builds

This KHACHIMO unit delivers 1200 watts through an ATX form factor and carries 80 PLUS Gold certification. Resonant LLC topology with DC-to-DC conversion supplies clean, consistent power while reducing coil whine. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. It suits workstations and enthusiast desktops that demand high, stable output.

For systems needing 1200W

Builders who want the fan to stay off at low and medium loads benefit from the Zero RPM fan mode. The design targets lower power consumption, less noise and cooler temperatures under typical workloads. It is not for compact cases that require SFX or TFX dimensions, nor for builds that need less than 1200 watts and prefer a smaller, lower-cost unit.

80 PLUS Gold efficiency rating

The certified efficiency level confirms high-efficiency operation across the load range, directly lowering power draw, noise and operating temperatures. This single specification tells you whether the unit meets your efficiency and thermal targets for a 1200W ATX power supply.

Questions about this item

How loud does the 1200W unit get during an all-day workload?

Zero RPM Fan Mode stops the fan entirely at low and medium loads, and 80 PLUS Gold efficiency reduces waste heat, so noise stays minimal even after hours of use.

What existing parts must I already have for this ATX power supply to work in my system?

You need a case that accepts a standard ATX form-factor PSU and a motherboard with 24-pin ATX plus EPS power connectors.

Will the RG-PA1200I play nicely with older components I plan to keep?

Resonant LLC topology with DC-to-DC conversion delivers clean, stable rails that older hardware expects, and Modern Standby support enables deeper sleep states on legacy platforms.
