1200W ATX Power Supply

This KHACHIMO unit delivers 1200 watts through an ATX form factor with 80 PLUS Gold certification. It uses resonant LLC topology with DC-to-DC conversion to provide clean, consistent power and reduce coil whine. The supply is Modern Standby compatible for extremely fast wake-from-sleep times and better low-load efficiency. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation.

Desktop builders needing high output

Suits system integrators and enthusiasts who want 1200 watts of Gold-rated power with silent running at idle and Modern Standby support. Not for builders who need less output and have no use for Modern Standby features. Not for compact chassis that cannot accommodate a standard ATX power supply. Not for users who require specialised server redundancy features not listed here.

80 PLUS Gold efficiency rating

The Gold certification confirms high efficiency operation for lower power consumption, less noise and cooler temperatures under typical loads. This rating is the single specification that decides whether the unit meets your efficiency and thermal targets. Resonant LLC topology with DC-to-DC conversion supports this efficiency while enabling energy-efficient sleep states. Zero RPM fan mode complements the rating by eliminating fan noise when the load is light.

Questions about this item

Will this 1200W ATX unit fit and power an older motherboard that still uses a 24-pin and 4-pin CPU connector?

Yes, the ATX form factor and standard 24-pin plus 4/8-pin CPU connectors are compatible with legacy boards, and the 1200W capacity provides ample headroom for older components.

How can I confirm the Zero RPM fan mode is active after installation?

Under light loads the fan remains completely still; you can verify silence at idle and watch the fan stay motionless through a case window until the load rises above the Zero RPM threshold.

Does the package contain the modular cables needed for GPU and drive connections, or are they sold separately?

The box includes the PSU unit, a full set of modular cables for motherboard, CPU, PCIe and peripheral power, mounting screws and a user manual; no extra cables are required.
