  • Clean, stable power delivery from resonant LLC with DC-to-DC conversion
  • 300 W ATX unit built as direct replacement for FSP300-70MP

300W ATX Replacement Unit

This KHACHIMO switching power supply is built as a direct 300W ATX replacement for the FSP300-70MP model. It suits system builders and repair technicians who need a compatible unit for existing chassis and motherboards requiring this specific form factor and output.

Gold Efficiency With Silent Fan Mode

The 80 PLUS Gold certification reduces wasted energy and lowers operating temperatures under load. A Zero RPM fan mode stops the cooling fan completely at low and medium loads, while resonant LLC topology with DC-to-DC conversion minimises coil whine and delivers cleaner power for modern sleep states.

Modern Standby Support For Fast Wake

Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. This feature is the deciding factor for systems that rely on connected standby behaviour; without it the platform cannot enter or resume from the required low-power states correctly.

Questions about this item

Does the fan on this 300W ATX unit ever need replacement after years of continuous use?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, reducing wear; under heavy sustained loads the fan will spin and may eventually require replacement like any mechanical cooler.

What thermal limit appears first when this supply runs at full 300W output for hours?

At continuous full load the internal temperature rise will trigger the fan to run at higher speed, making fan noise the first noticeable limit before any protection circuit engages.

How loud and hot does this 80 PLUS Gold ATX supply get during an all-day workload?

Gold efficiency and the LLC resonant topology keep waste heat low, while Zero RPM mode stays silent at light loads; under sustained load the fan runs audibly but temperatures remain controlled.
