KHACHIMO Power Supply For Power-one 250W CPA250-4530S195

SKU CH-HG5X-AFYDS

A 250 W ATX power supply built for Power-one CPA250-4530S195 with 80 PLUS Gold efficiency, Zero RPM fan mode and Modern Standby support

  • TypeATX
  • Modern Standby compatibility for extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency for lower power consumption, less noise, 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, consistent power and reduces coil whine
  • 250 W ATX power supply designed as a replacement for Power-one CPA250-4530S195

250W ATX Power Supply for Power-one Replacement

This 250W ATX unit is built as a direct replacement for the Power-one CPA250-4530S195. It suits system integrators and repair technicians who need a modern, efficient supply for legacy or compact chassis requiring this specific form factor. Buyers needing higher wattage for discrete graphics cards or multi-drive arrays should look elsewhere.

80 PLUS Gold Efficiency with Zero RPM Fan Mode

The 80 PLUS Gold certification delivers high efficiency across typical loads, reducing waste heat and overall power draw. A Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion further lowers coil whine and supports deeper sleep states.

Modern Standby Support for Faster Wake Times

Modern Standby compatibility enables extremely fast wake-from-sleep performance and improved low-load efficiency. The LLC resonant design combined with DC-to-DC conversion provides clean, consistent power delivery while allowing the platform to use more energy-efficient sleep states. No additional cables or software utilities are mentioned in the specifications.

Preguntas sobre este artículo

How do I install the ATX 250W unit and which step is often missed?

Mount the supply with four screws, connect the 24-pin ATX and CPU power cables, then verify the motherboard BIOS has Modern Standby enabled so the fast wake feature actually works.

What maintenance or replacement will this power supply need later?

The Zero RPM fan only spins above medium load, so dust builds up slowly; clean the intake grill once a year and replace the unit if coil whine appears after the 80 PLUS Gold efficiency drops.

What limit appears first under sustained load?

Continuous output is capped at 250W; the resonant LLC topology with DC-to-DC conversion protects voltage stability, but exceeding that wattage triggers shutdown before thermals become an issue.
