KHACHIMO PS-7270F 250W ATX power supply for EVOC 810 820

SKU CH-SAQQ-TDYB2

A 250W ATX power supply for EVOC 810 and 820 systems, 80 PLUS Gold certified with Modern Standby compatibility, Zero RPM fan mode, and resonant LLC topology with DC-to-DC conversion for clean.

  • Product typeATX
  • Modern Standby gives extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency for lower power consumption, less noise and cooler temperatures
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean power, reduces coil whine and enables efficient sleep states
  • Designed as a 250W ATX replacement for EVOC 810 820 units

Targeted replacement for EVOC 810 and 820 systems

This 250W ATX power supply is built to fit EVOC 810 and 820 chassis directly. It replaces the earlier PS-7270B and PS-7270C units without adapter cables or bracket changes. The form factor matches the original mounting points for a straight swap.

Gold-rated efficiency with silent low-load operation

The unit carries 80 PLUS Gold certification, so it converts mains power efficiently and runs cooler under typical loads. A Zero RPM fan mode stops the fan completely at low and medium loads, removing audible noise during idle or light work. Resonant LLC topology with DC-to-DC conversion delivers clean voltage regulation and suppresses coil whine.

Modern Standby support for faster wake times

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and deeper low-power states than legacy sleep modes. The jump is worthwhile for systems that cycle through sleep frequently or sit idle for long periods. Builders needing higher wattage for discrete graphics or multi-drive arrays should look elsewhere.
