Compact 1U ATX Supply for Small Chassis

The KHACHIMO FLEX Small 1U 250W is an ATX power supply built for 1U rackmount or slim desktop enclosures where height is restricted. It delivers 250 W of continuous power and carries 80 PLUS Gold certification for high efficiency across typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation.

Suited for Quiet 1U Builds.

This unit suits builders assembling 1U servers, thin clients, or compact workstations that prioritise low noise and efficient sleep states. The resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine. It is not for systems that require more than 250 W, such as builds with discrete graphics cards, multiple high-wattage CPUs, or large drive arrays. Buyers needing higher wattage or standard ATX dimensions should look at larger form-factor supplies.

250 W Output Defines the Power Budget

The single specification that decides fit is the 250 W rated output. Every component in the system — processor, memory, storage, and add-in cards — must stay within this limit under full load. Exceeding it will cause instability or shutdown. Verify the total power draw of your planned configuration before selecting this supply.

Perguntas sobre este artigo

What form factor does this 250W unit use for a 1U rack mount?

It follows the ATX standard, so it fits any chassis or rack tray designed for ATX power supplies.

How do I enable the Zero RPM fan mode on this supply?

The mode activates automatically at low and medium loads; no BIOS setting or software switch is required.

Will the 80 PLUS Gold efficiency rating degrade over time?

The rating reflects the design efficiency at certified load points; normal aging does not change the certified level.
