1U Industrial ATX Supply

The KHACHIMO FLEX300M is a 1U industrial ATX power supply rated at 300W. It is built for rackmount chassis and compact enclosures that require a standard ATX connector layout in a thin profile. The unit is supplied new and has been tested for basic operation before shipment.

Suited for slim servers not for high power builds

This supply fits 1U rackmount servers, industrial PCs and shallow workstations where a full-height PSU cannot be installed. It serves integrators who need a reliable 300W ATX source in a slim form factor. Builders planning multi-GPU workstations or high-wattage desktop configurations should look at higher-capacity units instead.

300W ATX output decides fit

The single specification that determines compatibility is the 300W ATX power rating. If the target system demands more than 300W combined draw this unit will not be sufficient. If the load stays within that limit the FLEX300M provides the correct connector set for a standard ATX motherboard.
