High-capacity ATX power supply

The KHACHIMO CP2000AC54PEZ delivers 2000W of continuous ATX power for workstations and high-end desktop builds that demand substantial headroom. It targets system integrators and enthusiasts assembling multi-GPU or heavily overclocked configurations where sustained output matters.

80 PLUS Gold efficiency under load

The 80 PLUS Gold certification confirms high efficiency across typical operating ranges, reducing waste heat and keeping internal temperatures lower during extended sessions. Resonant LLC topology with DC-to-DC conversion maintains tight voltage regulation and clean power delivery when the system runs at high utilisation for long periods.

Check connector count and chassis clearance

Verify that your motherboard and graphics cards match the native cable complement supplied with this unit before ordering. Ensure the physical length of the power supply fits your case and that the rear mounting pattern aligns with standard ATX screw positions. Buyers who need modular cabling or a shorter form factor should look elsewhere.

Questions about this item

How loud and hot does the KHACHIMO CP2000AC54PEZ get under continuous load?

The 80 PLUS Gold rating means high efficiency, so it draws less power from the wall and runs cooler. Zero RPM mode stops the fan completely at low and medium loads for silent operation, while the LLC resonant topology reduces coil whine.

What must my build already have to use this 2000W unit?

Your case needs to accept a standard ATX power supply, and your components must be able to draw power through the native ATX connectors this unit provides.

Will this supply work reliably with older parts I want to keep?

Modern Standby support enables efficient low-power sleep states, and the DC-to-DC conversion with LLC topology delivers clean, stable voltages that older hardware expects.
