KHACHIMO 400W ATX Power Supply

This 400W ATX unit delivers a 53.5V 7.5A output for compatible POWERLD systems. It is built for users replacing an existing PSU or assembling a workstation that requires this specific voltage rail. The 80 PLUS Gold certification ensures high efficiency across typical loads.

Gold Efficiency with Zero RPM Fan

The 80 PLUS Gold rating reduces power draw, heat output and fan noise during everyday use. A Zero RPM mode stops the fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion provides clean power and minimises coil whine.

Modern Standby Support for Fast Wake

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. This suits builders who want responsive sleep states without the delay of traditional standby. It is not suited for systems requiring higher wattage or different voltage outputs.

Perguntas sobre este artigo

Does this 53.5 V 7.5 A ATX unit meet 80 PLUS Gold efficiency targets?

Yes, it is 80 PLUS Gold certified, so it delivers high efficiency operation that lowers power consumption, noise and operating temperatures.

What physical space does this ATX power supply need inside a case?

It uses the standard ATX form factor, so it fits any chassis with a regular ATX PSU mounting area and the usual screw pattern.

Which cables must be connected during installation to enable Modern Standby?

Plug the 24-pin ATX main connector and the 4- or 8-pin CPU power cable securely; the LLC resonant topology and DC-to-DC conversion then handle the low-power sleep states automatically.
