150 W ATX power supply

The KHACHIMO GW-D19-150B is a new 150 W ATX power supply built with resonant LLC topology and DC-to-DC conversion. It carries 80 PLUS Gold certification for high efficiency and includes a zero RPM fan mode that stops the fan at low and medium loads. Modern Standby compatibility enables very fast wake-from-sleep times and improved low-load efficiency.

Best for compact low-power builds

This unit suits small-form-factor systems, thin clients or embedded PCs that draw modest power and benefit from silent operation at idle. It is not for builds that need higher total output, auxiliary PCIe connectors or server-grade redundancy. Buyers planning discrete graphics cards or multi-drive arrays should look at higher-capacity units.

150 W continuous rating

The single figure that decides fit is the 150 W continuous power rating. If the complete system load stays below this level the supply will deliver clean, stable power with Gold-class efficiency; if the load exceeds it, the unit cannot support the build.

Questions about this item

Will the 150 W ATX unit run stably with an older motherboard that only has a 20-pin main connector and a 4-pin CPU plug?

The power supply follows the ATX form factor and provides a 24-pin main connector plus a 4-pin CPU connector; a 20-pin motherboard can use the first 20 pins of the 24-pin plug.

How can I confirm the 80 PLUS Gold efficiency and Modern Standby support are active after installation?

In the BIOS enable Modern Standby, then observe near-instant wake times and the fan staying off at idle — both indicate the Gold-rated platform is operating as designed.

Which cables are permanently attached to the 150 W unit and what must I source separately?

The fixed ATX 24-pin and CPU 4-pin leads are included; any PCIe power cables for a graphics card would need to be purchased separately.
