1U ATX Power Supply for Compact Builds

This KHACHIMO 1U ATX power supply delivers 350 W of continuous power in a rack-friendly form factor. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion for stable voltage regulation. Modern Standby compatibility ensures rapid wake-from-sleep performance.

Suited for 1U Servers and Low-Profile Workstations

The slim 1U height fits shallow chassis where standard PSUs cannot be installed. Zero RPM fan mode keeps acoustics near-silent at low and medium loads. Builders needing higher wattage for multi-GPU configurations or power-hungry CPUs should look at larger-capacity units instead.

350 W Continuous Output Rating

The single decisive specification is the 350 W maximum output, which defines the total system power budget this unit can support. Verify that the combined draw of all components stays within this limit before purchase.

Questions about this item

Does the 1U form factor require a specific chassis and ATX motherboard?

Yes, the 1U height fits rack or slim cases designed for that form factor, and the ATX connector set plugs into a standard ATX motherboard.

Will the 350 W capacity support older components that draw more power at startup?

The 350 W rating and DC-to-DC conversion deliver stable voltage during transient loads, so legacy drives and expansion cards start reliably.

How can I confirm the Zero RPM fan mode is active after installation?

Under light workloads the fan stops spinning completely; you can verify silent operation by listening for zero fan noise at idle.
