1450W ATX power supply for high-demand builds

The KHACHIMO G8 Z4 delivers 1450 watts of continuous ATX power for workstations and enthusiast systems that draw heavy loads. It is built for users who need reliable energy delivery without compromise. Buyers who need a lower-wattage unit for a basic office PC will find this model oversized.

Sustained-load behaviour

80 PLUS Gold certification means the unit maintains high efficiency across typical operating ranges, reducing waste heat and keeping internal temperatures lower during long rendering or compute sessions. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power under continuous demand. The fan remains off at low and medium loads through Zero RPM mode, so acoustic output stays minimal until thermal conditions require active cooling.

Build quality and connector implications

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and better low-load efficiency for systems that frequently enter sleep states. The topology reduces coil whine, contributing to quieter operation in noise-sensitive environments. Part numbers 851385-001 and 851385-003 identify this specific revision for compatibility verification.

Questions about this item

How much noise and heat should I expect when the 1450W unit runs all day under load?

At 80 PLUS Gold efficiency the supply wastes less power as heat, and the Zero RPM Fan Mode keeps the fan off at low and medium loads for near-silent operation.

Which cables or connectors must my build already provide for this ATX supply to work?

It uses the standard ATX form factor, so your case and motherboard need the usual 24-pin ATX, CPU EPS and PCIe power connectors that come with any modern build.

Will the Resonant LLC topology and Modern Standby support cause issues with an older motherboard that lacks Modern Standby?

The topology simply delivers cleaner power and reduces coil whine; Modern Standby compatibility is optional and does not prevent the unit from working with older boards.
