300W ATX Gold power supply

The KHACHIMO DPS-300AB-81 G delivers 300W of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency, lowering energy use and heat output. Modern Standby compatibility ensures extremely fast wake-from-sleep times. This unit suits office PCs, compact workstations, or low-power home builds that value quiet, efficient operation.

Compatibility checklist before ordering

Verify your chassis accepts a standard ATX power supply and that the combined system draw stays within the 300W rating. Confirm the motherboard uses a 24-pin ATX main connector and the CPU requires the matching 4-pin or 8-pin EPS connector supplied with the unit. Ensure the case layout allows airflow to the PSU intake and exhaust vents for the fan to operate correctly.

Build quality and daily use

Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine for quieter running. Zero RPM fan mode stops the cooling fan entirely at low and medium loads, enabling near-silent operation during routine tasks. The Gold-rated efficiency keeps temperatures lower, contributing to component longevity and a more comfortable environment.
