KHACHIMO GCS350PS28 28V 12.5A 350W power supply

350W ATX power supply for Modern Standby systems

The KHACHIMO GCS350PS28 delivers 350 watts of continuous power from a single 28 volt rail rated at 12.5 amps. Built to the ATX form factor it fits standard desktop chassis and carries 80 PLUS Gold certification for high efficiency across typical loads. Resonant LLC topology with DC-to-DC conversion supplies clean, stable voltages while enabling deeper sleep states. Modern Standby compatibility ensures extremely fast wake-from-sleep times and improved low-load efficiency.

Ideal for compact builds that prioritise quiet

This unit suits builders who want near-silent performance at idle and moderate workloads because the Zero RPM fan mode stops the fan completely under light demand. Systems that require multiple high-power graphics cards or sustained loads well above 350 watts should look at higher-capacity models. The fixed 28 volt output design also means it is not a direct replacement for standard multi-rail ATX units that provide 12 volt, 5 volt and 3.3 volt rails.

350 watt capacity with Gold-rated headroom

At 80 PLUS Gold efficiency the supply comfortably handles mainstream CPUs, single mid-range GPUs and several drives while wasting less energy as heat. Continuous output is limited to 350 watts so heavily overclocked configurations or dual-card setups will exceed its capability. The single 28 volt 12.5 amp rail provides up to 350 watts on that rail alone; total system draw must stay within this ceiling for stable operation.
