KHACHIMO 300W ATX Power Supply

The KHACHIMO DPS-300LB A is a 300W ATX power supply built for modern desktop PCs. It suits office workstations, home PCs and compact builds that require reliable power delivery and quiet operation.

300W capacity with 80 PLUS Gold efficiency

The 300W rating handles typical mid-range components including mainstream processors and integrated graphics comfortably. High efficiency reduces waste heat and keeps fan speeds low, though the unit reaches its limit with power-hungry discrete graphics cards or heavily overclocked systems.

Upgrading from basic group-regulated units

Replacing an older group-regulated PSU brings DC-to-DC conversion, resonant LLC topology and Modern Standby support for cleaner voltage regulation and faster sleep wake times. The jump is worthwhile when building a new system or when an existing unit lacks Gold efficiency, zero-fan mode or support for low-power sleep states.
