Compact 1U Gold power supply

The KHACHIMO Silent 1U 250W 80 PLUS Gold is a new 1U form-factor ATX power supply rated at 250 watts. It is built for slim chassis where vertical space is limited but reliable delivery is required. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine.

Ideal for quiet 1U builds

This unit suits system integrators and DIY builders assembling compact workstations, edge appliances or home servers that demand near-silent operation. Modern Standby support enables extremely fast wake-from-sleep and better low-load efficiency. Zero RPM fan mode keeps the fan stopped at low and medium loads. Builders needing more than 250 watts or a taller form factor should look elsewhere.

250 watt 80 PLUS Gold output

The single specification that decides fit is the 250 watt 80 PLUS Gold rating, which confirms high efficiency for lower power consumption, less noise and cooler temperatures. Match this output to the total system draw before purchasing.

Questions about this item

How quiet is the 250 W unit when it runs all day in a 1U chassis?

The 80 PLUS Gold rating and Zero RPM fan mode keep the fan off at low and medium loads, while the resonant LLC topology with DC-to-DC conversion reduces coil whine for near-silent operation.

Which cables or connectors must my build already provide for this ATX supply to work?

It uses a standard ATX form factor, so your case and motherboard need matching ATX mounting points and a 24-pin main connector plus the usual CPU and peripheral leads.

Will the Modern Standby support work with an older motherboard that lacks that feature?

The supply is compatible with Modern Standby for faster wake times, but it will still deliver clean power to older boards that only support traditional sleep states.
