231W ATX power supply

The KHACHIMO DPS-231CB A delivers up to 231 watts of continuous power in a standard ATX form factor. It is suited for compact desktop builds, office workstations or upgrade projects where a modest power budget is required. The unit targets users who prioritise efficiency and quiet operation over high-output headroom. It is not for builders who need more storage or expansion capacity than a low-wattage supply can support.

Sustained-load behaviour

The resonant LLC topology with DC-to-DC conversion maintains clean, consistent output during prolonged workloads rather than only in short bursts. This design reduces coil whine and supports energy-efficient sleep states while keeping voltages stable. The 80 PLUS Gold certification confirms high efficiency across typical load ranges, lowering heat output and fan demand. It is not for systems that push continuous loads near the unit’s maximum rating for extended periods.

ATX interface limits

The supply provides a 4.2 V rail rated at 55 A, defining the practical current ceiling for that voltage domain. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency within the ATX specification. Zero RPM fan mode allows the cooling fan to switch off entirely at low and medium loads for near-silent operation. It is not for configurations that require auxiliary connectors or higher rail currents than the design provides.

Perguntas sobre este artigo

How much heat and noise does the 231 W unit produce when the PC runs all day?

The 80 PLUS Gold rating keeps efficiency high, so less waste heat is generated and the fan can stay off longer. Zero RPM mode stops the fan completely at low and medium loads for near-silent operation.

What connectors or cables must I already have for this PSU to work in my build?

It uses a standard ATX form factor, so your case must accept an ATX power supply and your motherboard needs the usual 24-pin ATX and 4/8-pin CPU power connectors.

Will the DPS-231CB A power older components such as a legacy motherboard or mechanical drives without issues?

Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine, making it compatible with older hardware that is sensitive to voltage ripple.
