KHACHIMO 250W ATX Power Supply Gold Zero RPM

SKU CH-MKE9-PAFNY

A 250W ATX power supply with 80 PLUS Gold efficiency, Zero RPM fan mode for silent low-load operation, and Modern Standby support

  • TypeATX
  • Modern Standby compatible for near-instant wake from sleep
  • 80 PLUS Gold certification cuts energy waste and heat
  • Zero RPM fan mode stops the fan at low load
  • Resonant LLC with DC-to-DC delivers clean, stable power
  • ATX form factor fits standard desktop chassis

ATX 250W Gold PSU

This 250W ATX power supply delivers 80 PLUS Gold efficiency for lower consumption and cooler operation. It targets builders of compact or low-power systems such as DVR and NVR appliances. The unit supports Modern Standby for extremely fast wake-from-sleep times and better low-load efficiency.

Capacity and headroom

Rated at 250 watts, the unit comfortably handles modest platforms with integrated graphics and a few drives. Heavy discrete GPUs or multi-drive arrays will exceed its headroom, so high-end gaming or workstation builds should look elsewhere. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power across the operating range.

Build quality and connectors

Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. The same topology reduces coil whine and enables more energy-efficient sleep states. Standard ATX mounting and cabling fit typical chassis without special brackets or adapters.

Perguntas sobre este artigo

Will this 250W ATX unit power my older motherboard that only has a 20-pin main connector and a 4-pin CPU plug?

The supply follows the ATX form factor and provides a standard 24-pin main connector that is backward-compatible with 20-pin boards; the 4+4-pin EPS cable can be split to fit a 4-pin CPU socket.

How can I verify the fan is behaving correctly in Zero RPM mode after I install the PSU?

At low and medium loads the fan should remain completely still; you can confirm this by listening for silence and watching the blades through the grille while the system idles.

What cables come in the box with this power supply?

The unit ships with the fixed 24-pin ATX motherboard cable, a 4+4-pin EPS/CPU cable, PCIe connectors for graphics cards, and peripheral leads for drives; no extra cables are required for a typical build.
