750W ATX power supply

The KHACHIMO 750W ATX unit delivers 80 PLUS Gold certified efficiency for desktop systems. Resonant LLC topology with DC-to-DC conversion provides clean power and supports modern sleep states. Zero RPM fan mode stops the fan at low and medium loads for silent operation. It is built for builders who want efficient, quiet power.

Modern Standby and silent builds

This supply suits PCs that use Modern Standby for fast wake times and low-load efficiency. The fan-less mode at typical loads benefits quiet-focused workstations or media PCs. Builders needing more than 750W output or non-ATX form factors should look elsewhere. Systems requiring specialised server-grade redundancy are not a match.

750W capacity and headroom

The 750W rating comfortably handles mainstream CPUs and single high-end GPUs under full load. Efficiency peaks at typical loads, reducing heat and electricity cost. Sustained loads beyond the rated wattage will trigger protection or shutdown. Multi-GPU configurations or extreme overclocking headroom exceed what this unit provides.

Questions about this item

What motherboard power connectors does the 750W ATX unit require to be present on my board?

The supply is built to the ATX form factor so it expects a standard 24-pin main power socket and a 4+4-pin CPU power socket on the motherboard.

Will the 80 PLUS Gold certified 750W PSU work with an older system that does not support Modern Standby?

Yes, Modern Standby compatibility is an added feature for newer platforms; the unit still delivers standard ATX power to any compatible motherboard.

How can I confirm the Zero RPM fan mode is active on the EFRP-G757 after installation?

Under light or medium load the cooling fan should stop completely; you can verify this visually or by listening for the absence of fan noise.
