270W ATX Power Supply

The KHACHIMO SPI270F4B24 is a 270W ATX power supply built for compact or low-power desktop systems. It delivers 80 PLUS Gold certified efficiency to reduce electricity draw and heat output. Modern Standby compatibility enables extremely fast wake-from-sleep transitions. The unit targets builders who need reliable, quiet power for small form factor or office workstations.

Upgrade from lower efficiency units

This supply replaces older bronze or unrated units that waste more energy at the wall and generate extra heat. The resonant LLC topology with DC-to-DC conversion provides cleaner voltage regulation and reduces coil whine. The efficiency jump is worth it when building a system that runs long hours or sits in a noise-sensitive environment. It also enables deeper, more energy efficient sleep states supported by modern platforms.

Capacity and headroom

At 270W this unit comfortably handles integrated graphics platforms, entry-level discrete cards, and typical office workloads with headroom for peripherals. Zero RPM fan mode keeps the system near-silent at low and medium loads by stopping the fan entirely. It runs out of headroom with high-wattage CPUs or mid-to-high-end graphics cards that demand sustained power beyond the rated output. Builders planning such components need a higher capacity supply.

Questions about this item

Will the standard ATX form factor of this 270W unit fit my existing case mounting points?

Yes, the power supply uses the standard ATX form factor so it aligns with the usual four-screw mounting pattern found in most chassis designed for ATX units.

Which cables must be connected during installation to enable Modern Standby and the 80 PLUS Gold efficiency features?

Connect the 24-pin ATX motherboard cable and the 4-pin or 8-pin CPU power cable; Modern Standby and the certified efficiency operate automatically once the unit receives AC power and the motherboard signals the correct sleep state.

How do I know when the cooling fan needs cleaning or replacement on this model?

The Zero RPM fan mode keeps the fan off at low and medium loads; if you hear unusual noise or the fan fails to spin under heavy load, clean the blades with compressed air or replace the fan assembly.
