KHACHIMO 330W ATX Power Supply D330EA-00 WXJ4K DPS-330EB A

SKU CH-EHNV-3BEF8

330W ATX unit with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support for fast, quiet wake-ups

  • Product typeATX
  • Modern Standby support gives extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification means high efficiency for lower power consumption, less noise and cooler temperatures
  • Zero RPM fan mode stops the cooling fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine
  • 330W ATX power supply provides reliable power for compatible systems

Compact ATX power for office builds

This 330 W ATX unit targets small-form-factor desktops and office refreshes where a full-size supply is unnecessary. It delivers the standard connector set for mainstream motherboards and drives. Builders needing higher wattage for discrete graphics cards or multi-drive arrays should look elsewhere.

Sustained-load behaviour

The 80 PLUS Gold certification means the supply maintains high efficiency across typical workloads, reducing waste heat during long work sessions. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight when the system runs continuously. Modern Standby support allows rapid wake from low-power states without instability.

Thermals, noise and power draw

Zero RPM fan mode stops the fan completely at low and medium loads, yielding near-silent operation for everyday tasks. The efficient topology lowers overall power draw and keeps internal temperatures modest. Coil whine is reduced by the resonant design, contributing to a quieter chassis environment.

Questions about this item

How much heat and noise will the 330 W unit produce when running all day?

80 PLUS Gold certification means high efficiency, so less waste heat and lower fan speeds; Zero RPM mode stops the fan completely at low and medium loads for near-silent operation.

Which connectors must my build already have for this ATX supply to work?

A standard ATX 24-pin motherboard socket and a 4/8-pin CPU power connector are required; the unit includes the matching cables.

Will the DC-to-DC design and Modern Standby support work reliably with older components I keep?

Resonant LLC topology with DC-to-DC conversion delivers clean, stable power and reduces coil whine, while Modern Standby compatibility enables efficient sleep states on both new and legacy hardware.
