Power Supply For GW-XSP40AL-4.5V

The KHACHIMO ATX unit delivers 40 watts at 4.5 volts and 40 amps. It is built as a direct replacement for the GW-XSP40AL-4.5V model. Modern Standby compatibility gives extremely fast wake-from-sleep times and better low-load efficiency. The 80 PLUS Gold certification means high efficiency operation for lower power consumption, less noise, and cooler temperatures.

Check Your Current Unit

Confirm that the existing power supply is the GW-XSP40AL-4.5V and that the connector layout matches this replacement. Verify the chassis can accept a standard ATX form-factor unit. Ensure the system power draw does not exceed the 40 watt rating of this supply. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine for quieter operation.

Suits Low-Power ATX Replacements

This unit suits owners of the GW-XSP40AL-4.5V who need a new ATX power supply with Modern Standby support and Gold efficiency. The zero RPM fan mode stops the cooling fan at low and medium loads for near-silent operation. Builders needing higher wattage, different voltage rails, or a non-ATX form factor should look at other options.
