30 W 24 V ATX power supply

The KHACHIMO ZWS30B delivers 30 W of continuous power at 24 V with a 1.3 A output. It follows the ATX form factor and carries 80 PLUS Gold certification for high efficiency. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency.

Ideal for low-power ATX systems needing quiet

This unit suits builds that prioritise silent running and efficient sleep states. Zero RPM fan mode stops the cooling fan at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion reduces coil whine and provides clean, consistent power. It is not intended for configurations that require higher total wattage.

24 V 1.3 A single-rail output

The power supply provides a single 24 V rail rated at 1.3 A, which determines whether it can meet the load of the connected components. Verify that the system’s total draw stays within this 30 W limit before installation.

Questions about this item

How do I install the KHACHIMO ZWS30B into an ATX case and connect the 24-pin motherboard cable correctly?

Mount the unit in the standard ATX bay using four screws, then firmly seat the 24-pin main connector into the motherboard socket until the latch clicks; the step most often missed is forgetting to plug in the separate 4+4 pin CPU power cable nearby.

Which part of the ZWS30B will likely need replacement first after years of continuous operation?

The internal cooling fan is the primary wear item; its bearings degrade over time, and once the Zero RPM mode can no longer spin it up, temperatures rise and the unit should be swapped.

At what load does the 30W ZWS30B hit its thermal limit during sustained use?

Continuous output near the full 30W / 1.3A rating at 24V will trigger the protection circuit first, causing the supply to shut down until it cools.
