1000W 80 PLUS Gold ATX PSU

This KHACHIMO EP1000-UBZ is a 1000W ATX power supply rated 80 PLUS Gold. It delivers high efficiency across typical loads, reducing power draw, heat and fan noise. Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while minimising coil whine.

Suited to high-output builds needing quiet idle

The unit suits builders who want a high-output ATX supply with near-silent operation at low and medium loads thanks to a Zero RPM fan mode. It also fits systems that rely on Modern Standby for rapid wake times. Buyers who require a lower maximum wattage or a different form factor should consider other options.

1000W capacity with Gold efficiency headroom

The 1000W rating comfortably handles demanding multi-GPU configurations and heavily overclocked components while maintaining Gold-class efficiency. At lighter loads the fan remains off, keeping acoustics to a minimum. The design runs out of headroom only when sustained demand approaches the rated maximum.

Questions about this item

Does this ATX power supply need any extra cables or connectors beyond what comes in the box to power a standard desktop build?

It uses standard ATX connectors, so the cables included with the unit are sufficient for a typical motherboard, CPU, GPU and drive installation.

Will the Zero RPM fan mode still operate quietly if I keep an older graphics card that draws more power at idle?

The fan stays off at low and medium loads; a higher-idle GPU may push the unit past the medium threshold, causing the fan to spin.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

You can monitor input versus output power with a wall meter; the supply should show efficiency above 80 % at typical loads.
