1200W ATX power supply for high-output builds

This KHACHIMO DPS-1200AB-26A unit delivers 1200W of continuous power through an ATX form factor. It targets builders assembling workstations or enthusiast desktops that draw sustained heavy loads. The 80 PLUS Gold certification confirms high efficiency across typical operating ranges.

Resonant LLC topology

The resonant LLC topology paired with DC-to-DC conversion maintains tight voltage regulation during extended heavy draws. This design reduces coil whine and supports energy-efficient sleep states without sacrificing rail stability. Efficiency stays high even when the system runs for long periods at significant utilisation.

Replaces lower-wattage

The jump is worth it when the current supply cannot sustain peak demand or runs loud under load. Zero RPM fan mode stops the fan at low and medium loads for near-silent operation. Modern Standby compatibility adds extremely fast wake-from-sleep times and better low-load efficiency. Buyers who need less than 1200W or do not require Gold efficiency will not benefit from the extra capacity.

Questions about this item

Does the 1200W unit stay quiet and cool when it runs continuously at high load?

The 80 PLUS Gold certification means high efficiency, so less waste heat and lower fan speeds, and Zero RPM mode stops the fan entirely at low and medium loads.

What must my PC already have to use this ATX power supply?

It fits a standard ATX case and connects to an ATX motherboard, CPU and GPU power sockets; the resonant LLC topology with DC-to-DC conversion delivers clean power for modern components.

Will this supply work reliably with the older hardware I plan to keep in the build?

Modern Standby compatibility enables efficient low-power sleep states, and the DC-to-DC design provides stable voltages that older parts expect.
