600W ATX power supply for modern PCs

The KHACHIMO Z420 600W unit delivers 600 watts of continuous power through a standard ATX form factor. It targets builders who need reliable energy for mid-range components and Modern Standby support. The design suits systems that prioritise efficient sleep states and quick wake times. It is not for configurations that demand multiple high-end graphics cards or extreme overclocking headroom.

80 PLUS Gold efficiency with 600W capacity

Rated at 600W, the supply meets 80 PLUS Gold certification for high efficiency across typical loads, reducing waste heat and fan noise. The resonant LLC topology with DC-to-DC conversion provides stable voltage regulation for CPU and GPU rails. At low and medium loads the Zero RPM fan mode stops the fan completely for silent operation. Heavy sustained loads will eventually spin the fan and approach the unit's rated limit.

Modern Standby and quiet cooling features

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency for contemporary operating systems. The Zero RPM mode keeps acoustics near zero during office work or media playback. Resonant LLC topology with DC-to-DC conversion minimises coil whine and supports deeper sleep states. Builders needing legacy connectors or higher wattage for multi-GPU arrays should look elsewhere.

Questions about this item

Will the 600W Z420 unit power my older ATX motherboard and CPU without adapter cables?

The power supply uses a standard ATX form factor and 600W output, so it fits and powers legacy ATX boards directly with its fixed cable set.

How can I confirm the 80 PLUS Gold efficiency and Zero RPM fan mode are active after installation?

At low load the fan stays off completely, and the 80 PLUS Gold rating means the unit runs cooler and quieter than lower-rated supplies.

Does the box include every cable I need for a typical ATX build or must I buy extra leads?

The unit ships with the fixed ATX cable set only; any additional PCIe or proprietary workstation leads must be purchased separately.
