KHACHIMO ITX FLEX DC-DC 1U S3 K39 A35 550W 600W Power Supply

Compact ITX Flex Power Supply

The KHACHIMO ITX Flex unit is a DC-to-DC ATX power supply designed for small-form-factor builds that require a 1U footprint. It delivers up to 600 W peak output with a 550 W continuous rating and carries 80 PLUS Gold certification for high efficiency. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency.

Verify Physical and Electrical Fit

Confirm that your chassis accepts a 1U ITX Flex form factor and that the ATX connector layout matches your motherboard. The DC-to-DC topology with resonant LLC conversion provides clean power and supports deeper sleep states, so ensure your board implements the corresponding power-management features. Zero RPM fan mode activates at low and medium loads, which depends on the thermal profile of your specific configuration.

Ideal for Quiet Small-Form-Factor Systems

This supply suits builders assembling compact workstations or HTPCs who prioritise silent operation and efficient sleep states. It is not intended for full-size ATX cases that expect standard PS/2 dimensions. Buyers who need higher continuous wattage or modular cabling for extensive GPU configurations should look at larger form-factor units.
