KHACHIMO FSP ITX HTPC FLEX 1U K39 600W Power Supply

Compact 600 W Flex ATX Supply

The KHACHIMO FSP K39 is a 600 W Flex ATX power supply built for small-form-factor PCs and 1 U rack appliances. It delivers full ATX power in a 39 mm high chassis that fits slim HTPC cases and shallow server nodes. Modern Standby support enables rapid wake-from-sleep and improved low-load efficiency. An 80 PLUS Gold rating confirms high conversion efficiency across typical loads.

Suited for high-density builds.

This unit targets builders assembling compact workstations, digital-signage players or 1 U servers that require a Flex ATX footprint and 600 W of continuous power. The Zero RPM fan mode keeps acoustics near zero at idle and moderate loads, benefiting living-room or office deployments. Builders using full-size ATX cases with standard PSU mounting brackets should look elsewhere, as the physical dimensions and screw pattern differ from conventional ATX power supplies.

600 W continuous output in a 39 mm Flex ATX form

The single deciding specification is the 600 W rated output delivered within the 39 mm Flex ATX envelope. If your chassis accepts a Flex ATX supply and your components demand up to 600 W, this model meets the requirement; if the case only fits a thinner profile or the build needs more than 600 W, another solution is required.
