Compact 1U Power Supply

This KHACHIMO unit is a 1U form-factor ATX power supply rated at 200 watts continuous with a 250-watt peak capability. It is designed for small-chassis builds such as rack-mount servers, slim workstations or embedded appliances where vertical space is at a premium.

Build Integration

The 1U height lets the unit slide into shallow enclosures that cannot accept standard-height PSUs, freeing internal volume for additional drives or expansion cards. Its ATX connector set supports mainstream motherboards, while the DC-to-DC topology delivers stable minor rails without needing bulky group-regulated designs.

Sustained Load Behaviour

Under continuous load the 80 PLUS Gold certification ensures high efficiency, reducing waste heat and keeping internal temperatures lower. The Zero RPM fan mode keeps the unit silent at low and medium loads, while the resonant LLC topology maintains clean power delivery and suppresses coil whine during extended operation.

Questions about this item

What is the peak wattage the FLEX12V can deliver for short bursts?

The unit is rated for 200 W continuous and can reach 250 W peak for brief loads.

How quiet does the PSU stay when the system runs all day?

Zero RPM mode stops the fan at low and medium loads, and the LLC resonant topology with DC-to-DC conversion reduces coil whine for quieter operation.

Which motherboard power connector does this 1U supply use?

It follows the ATX form factor, so it connects to a standard 24-pin ATX motherboard socket.
