KHACHIMO 400W ATX Power Supply TMPC-400 FSP400-70MP 80 PLUS Gold

400W ATX Power Supply for Medical Systems

The KHACHIMO TMPC-400 is a 400W ATX power supply built for medical equipment and workstations that demand reliable, efficient power delivery. It carries 80 PLUS Gold certification, so it runs at high efficiency across typical loads, reducing waste heat and keeping internal temperatures lower. Resonant LLC topology with DC-to-DC conversion supplies clean, stable output and helps suppress coil whine. Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency.

Suited for Medical PCs and Quiet Workstations

This unit fits builders who need a Gold-rated ATX supply with a semi-passive fan mode for near-silent operation at low and medium loads. The zero-RPM feature stops the fan entirely when cooling demand is minimal, making it ideal for noise-sensitive environments such as clinics or recording spaces. It is not intended for high-wattage gaming rigs or multi-GPU configurations that require substantially more than 400W of continuous power. Buyers needing multiple PCIe power connectors or server-grade redundancy should look at higher-capacity platforms.

Semi-Passive Cooling and Efficient Sleep States

The zero-RPM fan mode changes daily acoustics by eliminating fan noise during light workloads and idle periods. Resonant LLC topology with DC-to-DC conversion reduces electrical noise and supports deeper, more energy-efficient sleep states without sacrificing voltage stability. Modern Standby support means the system can enter and exit low-power modes almost instantly, saving energy while keeping the workstation responsive. These features together lower audible noise and power draw without adding extra cables or software utilities.
