Compact 1U Gold power supply

The KHACHIMO SO-300PSU is a 1U form-factor ATX unit rated at 230 W continuous with a 250 W peak. It carries 80 PLUS Gold certification and uses resonant LLC topology with DC-to-DC conversion for clean output. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. A zero-RPM fan mode stops the fan at low and medium loads for near-silent operation.

Ideal for small-form-factor and silent builds

This supply suits builders assembling compact 1U systems or quiet workstations that benefit from Gold efficiency and fanless low-load running. Modern Standby support makes it a good match for systems that frequently enter low-power sleep states. It is not for configurations needing more than 230 W continuous delivery, nor for chassis that require a standard ATX-depth unit.

Rated 230 W continuous power

The single specification that decides fit is the 230 W continuous rating with a 250 W peak. If your component load stays within this envelope the unit will deliver Gold-class efficiency and quiet running; if the build demands higher sustained wattage you must choose a higher-rated supply.

Questions about this item

Should I choose the 230 W rated or the 250 W peak version?

The unit has a single 230 W continuous rating with a 250 W peak capability; pick it if your build stays under 230 W sustained load.

What does 80 PLUS Gold mean for my electricity bill and thermals?

It guarantees at least 80 % efficiency at typical loads, so less power is wasted as heat and the system runs cooler and quieter.

Which ATX standard does this supply follow and what does it limit?

It follows the ATX form factor, so it fits standard cases and its 230 W continuous output caps the total power available to all components.
