600 W ATX power supply for modern PCs

The KHACHIMO RS500 I610r-G delivers 600 W of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency across typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine.

Replaces older or lower-efficiency units

Upgrading from a non-modular or bronze-rated supply brings measurable gains in efficiency, acoustic profile, and sleep-state support. The zero-RPM fan mode stops the fan entirely at low and medium loads for near-silent operation. The jump is worth it when building or refreshing a system that spends long periods idle or in Modern Standby and values reduced heat output and noise.

Suits builders who prioritise quiet, efficient power

This unit fits users who want Gold-rated efficiency, silent low-load operation, and Modern Standby readiness in a 600 W ATX package. Buyers needing higher wattage for multi-GPU configurations or extreme overclocking headroom should look at higher-capacity models. Systems requiring specialised form factors such as SFX or TFX will need a different physical design.

Questions about this item

Does the ATX form-factor unit fit a standard ATX case cut-out?

Yes, it uses the standard ATX dimensions so it mounts in any case with an ATX power-supply opening.

Which cables must be connected during installation, and which step is often missed?

Connect the 24-pin ATX, 8-pin EPS and required PCIe cables; the step often missed is plugging in the 8-pin EPS connector near the CPU socket.

When should the internal cooling fan be checked or replaced?

The fan only spins under higher loads; inspect it during routine PC cleaning and replace it if bearing noise appears or it fails to start when the load rises.
