1U 600W ATX Gold PSU

The KHACHIMO unit is a 1U form-factor ATX power supply rated at 600W and certified 80 PLUS Gold. It targets builders of compact servers, rackmount workstations or space-constrained PCs who need efficient, standards-compliant power delivery. Modern Standby support enables rapid wake-from-sleep transitions and improved low-load efficiency.

Suited for quiet compact builds.

The Zero RPM fan mode stops the fan completely at low and medium loads, making it a strong choice for noise-sensitive environments such as home labs, media servers or office deployments. Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine. Systems requiring substantially more than 600W for multiple high-end graphics cards or extreme overclocking should consider higher-capacity alternatives.

Verify 1U clearance and cable reach before ordering

Confirm that your chassis accepts a 1U-height power supply and that the fixed cable lengths reach your motherboard, CPU and drive connectors without strain. Ensure the ATX 24-pin, EPS/CPU and peripheral connectors match your component requirements. Check that the rear mounting holes align with your case or rack rails and that airflow direction suits your enclosure layout.

Questions about this item

Will this power supply fit my ATX motherboard and case?

Yes, it follows the ATX form factor so it will mount in any standard ATX chassis and connect to the motherboard with the required 24-pin ATX and 8-pin EPS cables.

Can I keep my older components with this 600 W unit?

The 600 W capacity and DC-to-DC conversion deliver stable power to legacy drives and expansion cards while supporting modern low-power sleep states.

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

Under light or medium load the fan stops completely; you can confirm silent operation by listening for no fan noise during typical desktop use.
