KHACHIMO 750W ATX Power Supply

The KHACHIMO RH1288 2285 2288 V2 R520 is a 750W ATX switching power supply built for modern desktop PCs. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep transitions. Resonant LLC topology with DC-to-DC conversion delivers stable voltage regulation across all rails.

Ideal for efficiency-focused builds.

This unit suits builders who want low-load efficiency, near-silent operation at typical loads, and Modern Standby compatibility in a standard ATX form factor. Buyers needing more than 750W of continuous output or redundant power configurations should look at higher-capacity or server-grade alternatives instead.

750W capacity with Gold-rated headroom

The 750W rating comfortably handles mainstream CPUs and single high-end GPUs under full load while maintaining Gold efficiency levels. Zero RPM fan mode keeps acoustics minimal during light workloads. Systems drawing sustained loads beyond 750W or requiring multiple high-power graphics cards will exceed this unit's capability.

Questions about this item

Does this 750W ATX unit need a separate adapter or cable kit to power a standard motherboard and graphics card?

It ships as a complete ATX power supply with the fixed cables required for a typical motherboard 24-pin connector, CPU 4+4-pin connector and PCIe graphics connectors, so no extra adapter kit is necessary for a normal build.

Will the Zero RPM fan mode still keep the PSU cool when paired with an older CPU that draws little power at idle?

Yes, at low and medium loads the cooling fan switches off entirely while the resonant LLC topology with DC-to-DC conversion maintains stable, efficient output, so older low-draw CPUs run silently without thermal issues.

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

Under typical system load the fan should remain off or spin slowly thanks to the Zero RPM mode, and the unit should run cool to the touch, confirming the high-efficiency Gold-rated operation is functioning as intended.
