KHACHIMO 2900W ATX Power Supply ZXD3000V5.1R02

High-wattage ATX supply for demanding builds

The KHACHIMO 2900W ATX unit delivers 2900 watts of continuous power for workstations and multi-GPU systems that need very high headroom. Its 80 PLUS Gold certification keeps efficiency high across typical loads, reducing waste heat and fan noise. Modern Standby support allows extremely fast wake-from-sleep transitions and better low-load efficiency.

Gold efficiency and silent operation features

80 PLUS Gold certification means lower power draw, less noise and cooler temperatures during everyday use. Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power, reduces coil whine and enables more energy-efficient sleep states.

Check connectors and case clearance before ordering

Verify that your motherboard and graphics cards have the required ATX, EPS and PCIe connectors for a 2900W design. Confirm the physical length fits your chassis and that cable routing reaches all components without strain. Ensure your AC circuit can sustain the draw of a high-wattage supply under full load.
