KHACHIMO 500W ATX Gold PSU

The KHACHIMO 870 875 880 900 GA1 is a 500W ATX switching power supply built for modern desktop PCs. It carries 80 PLUS Gold certification for high efficiency and supports Modern Standby for rapid wake-from-sleep performance. This unit suits builders who want reliable power with low idle consumption.

500W capacity with Gold headroom

At 500W the unit comfortably handles mainstream CPUs and mid-range graphics cards under full load. The Gold-rated topology keeps losses low, so heat and fan noise stay modest even when the system draws close to the rated limit. It runs out of headroom for multi-GPU setups or extreme overclocking configurations.

Zero RPM fan and LLC-DC/DC build

A resonant LLC topology with DC-to-DC conversion delivers clean voltage regulation and reduces coil whine. The Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation. ATX form factor ensures standard case mounting, while Modern Standby compatibility enables deeper, more efficient sleep states.

Questions about this item

Will this 500W ATX unit work with a motherboard that still uses the standard 24-pin connector?

Yes, the KHACHIMO 870 875 880 900 GA1 is an ATX form-factor supply rated at 500W and uses the standard 24-pin main power connector required by current and older ATX motherboards.

How can I confirm the 80 PLUS Gold efficiency and Zero RPM fan mode are active after installation?

Under light loads the fan should remain completely still due to Zero RPM mode, and a power meter at the wall will show the high efficiency that matches 80 PLUS Gold certification across typical system draw.

Which cables are included with the PS-4501-2 or PS-4301-2 and what must I buy separately?

The box contains the power supply unit, an AC power cord, mounting screws and a user manual; all modular cables needed for motherboard, CPU, PCIe and drive connections are attached or supplied, so no extra cables are required for a standard build.
