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.

Questions about this item

Will the fan need replacement after years of continuous operation?

The unit uses a Zero RPM fan mode that stops the fan at low and medium loads, reducing wear and extending the fan's service life.

What limits sustained output before protection engages?

The power supply is rated for 2900 W; drawing more than that will trigger over-power protection and shut the unit down.

How loud and hot does it get when running all day at typical load?

80 PLUS Gold efficiency keeps heat lower, and the Zero RPM mode keeps the fan off at low and medium loads for near-silent operation.
