The KHACHIMO 5406zl ATX Power Supply

The KHACHIMO 5406zl is a new ATX power supply rated at 875W. It carries 80 PLUS Gold certification for high efficiency, lower power draw, and reduced heat output. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. A resonant LLC topology with DC-to-DC conversion delivers clean, consistent power while minimising coil whine.

Suitable for efficient ATX builds needing quiet

This unit suits builders who prioritise high efficiency and near-silent operation at low to medium loads through its Zero RPM fan mode. It supports Modern Standby for rapid sleep and wake cycles. It is not for systems requiring a different form factor or wattage rating, nor for users who need modular cabling if this unit lacks it.

875W output with 80 PLUS Gold efficiency

The single specification that decides fit is the 875W continuous power rating combined with 80 PLUS Gold certified efficiency. This defines the power ceiling and thermal behaviour for the entire build. Verify that your components' total draw stays within this limit and that the ATX form factor matches your chassis.

Questions about this item

How loud and hot does the 875W unit run when the system is under load all day?

The 80 PLUS Gold certification means high efficiency, so less waste heat and lower fan speeds; the Zero RPM mode keeps the fan off at low and medium loads for near-silent operation.

Which cables or connectors must my build already provide for this power supply to work?

It is an ATX-type unit, so it uses standard ATX motherboard and peripheral connectors; check that your case fits a regular ATX PSU.

Will the Modern Standby features work with an older motherboard that only supports traditional sleep states?

Modern Standby compatibility enables faster wake times and efficient low-load sleep states on supported platforms; older boards will still receive clean power from the LLC resonant topology with DC-to-DC conversion.
