24 V 250 W ATX Power Supply

This KHACHIMO unit delivers 250 watts on a 24 volt rail within a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency and runs a Resonant LLC topology with DC-to-DC conversion for clean power output. Modern Standby support enables extremely fast wake-from-sleep times and improved low-load efficiency.

Builders needing a 24 V ATX source

Suitable for systems that require a 24 volt ATX power supply with Gold-rated efficiency and semi-passive cooling. The Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation. Not for builds that require a different output voltage or a higher total wattage than 250 W.

24 volt output rail

The defining specification is the single 24 V rail rated for 250 W total power. This voltage level determines whether the unit matches the system's power distribution design. Verify that the target hardware expects a 24 V ATX input before purchase.

Questions about this item

What motherboard power connector does this ATX unit provide for the 24 V rail?

This ATX power supply delivers its rated 24 V output through the standard 24-pin main connector and matching 4/8-pin CPU connector required by compatible boards.

Can I keep my older 80 PLUS Bronze power supply as a spare while using this Gold-rated unit?

Yes, the 80 PLUS Gold certification means this supply runs more efficiently than Bronze units, so it generates less heat and noise while your older supply remains a functional backup.

How do I verify the Zero RPM fan mode is active after installation?

Under light loads the cooling fan stops completely; you can confirm silent operation by listening for zero fan noise while the system idles or runs basic tasks.
