Power Supply for Modern Standby Systems

The KHACHIMO LFA75F delivers 75 W of continuous power at 24 V and 3.2 A. It is built for desktop PCs that require an ATX form factor and fast wake-from-sleep capability. The 80 PLUS Gold certification ensures high efficiency across typical loads, reducing waste heat and fan noise.

Capacity and Headroom

Rated at 75 W, the unit comfortably runs entry-level CPUs, integrated graphics, and a modest set of peripherals. It reaches its limit when a discrete graphics card or multiple high-draw drives are added, so systems with heavier GPU demands will need a higher-wattage supply.

Included Features That Change Daily Use

Modern Standby compatibility enables extremely fast resume times and better low-load efficiency. Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion supplies clean power, reduces coil whine, and supports deeper sleep states.

Questions about this item

Will the 75 W ATX unit power a legacy motherboard that still uses a 20-pin main connector?

The supply follows the ATX form factor with a 24-pin main connector; a 20-pin motherboard will work if you leave the extra four pins unplugged.

How can I confirm the zero-RPM fan mode is active after I install the PSU?

At low and medium loads the cooling fan stops completely, so silent operation indicates the mode is working.

Which cables come in the box with the 24 V 3.2 A model?

The unit ships with the standard ATX cable set — 24-pin motherboard, 4+4-pin CPU and PCIe 6+2-pin leads — no extra connectors are included.
