1700W ATX power supply

The KHACHIMO MX480 is a 1700 watt ATX power supply built for high-end workstations and multi-GPU rigs that draw sustained heavy loads. Its 80 PLUS Gold certification and resonant LLC topology with DC-to-DC conversion deliver efficient, stable power across the full output range.

Sustained-load behaviour

Under continuous demand the resonant LLC design maintains tight voltage regulation while the DC-to-DC stage keeps minor rails clean, reducing coil whine and thermal stress. The fan remains off through low and medium loads via Zero RPM mode, spinning up only when temperatures require active cooling.

Compatibility checks

Verify that your case accepts a standard ATX form-factor unit and that your motherboard and graphics cards use the connectors this supply provides. Ensure the total system draw stays within the rated output and that your AC inlet matches the unit's input specification.

Questions about this item

How loud and hot does the KHACHIMO MX480 1700W get when running continuously?

The 80 PLUS Gold certification ensures high efficiency for lower power consumption, less noise, and cooler temperatures. Zero RPM Fan Mode stops the fan at low and medium loads for near-silent operation, while Resonant LLC topology reduces coil whine.

What connectors or components must my system already have to use this power supply?

This unit uses the standard ATX form factor, so your case must support ATX power supplies and your motherboard requires standard ATX power connectors for the 1700W output.

Will the KHACHIMO MX480 work reliably with older motherboards and graphics cards I plan to keep?

Yes, the ATX design and DC-to-DC conversion provide clean, consistent power compatible with legacy components, while Modern Standby support adds faster wake times for newer platforms.
