350W 1U power supply for compact systems

The KHACHIMO DH-355P delivers 350 watts of continuous power in a 1U form factor. It uses a resonant LLC topology with DC-to-DC conversion to supply stable voltage rails. The unit carries 80 PLUS Gold certification for high efficiency across typical loads. Modern Standby compatibility allows extremely fast wake-from-sleep transitions.

Check 1U clearance and ATX connector needs

Verify that your chassis accepts a 1U power supply and that the ATX connector layout matches your motherboard. Ensure the 350W rating covers the combined draw of your CPU, GPU and peripherals. Confirm that the unit’s physical dimensions fit the mounting points in your case. Review the cable complement to see if adapters are required for your build.

Suits small-form-factor and quiet builds

Builders assembling 1U servers, thin clients or compact workstations will appreciate the high efficiency and Zero RPM fan mode at low loads. The Gold-rated design reduces heat output and coil whine for noise-sensitive environments. Systems requiring higher wattage, redundant supplies or non-ATX form factors should consider other options.

Questions about this item

What comes in the box with the KHACHIMO DH-355P 350W unit and what must I source separately?

The package contains the power supply only. You will need to provide your own ATX power cable and any additional modular cables required by your build.

Which capacity of the KHACHIMO DH-355P should I choose for a compact 1U server build?

The single 350W model is the only version offered, making it the direct fit for 1U chassis that require this output.

What does the 80 PLUS Gold rating mean for daily power draw and heat in a live system?

It guarantees at least 80% efficiency at typical loads, reducing wasted electricity, lowering component temperatures and allowing the fan to stay off longer under light demand.
