KHACHIMO 400W 80 PLUS Gold Flex ATX Power Supply

SKU CH-0DSP-BXXFN

An 80 PLUS Gold ATX unit with Modern Standby support, zero-RPM fan mode and LLC resonant topology for quiet, efficient power

  • TypeATX
  • Modern Standby support for rapid wake from sleep
  • 80 PLUS Gold certification for high efficiency operation
  • Zero RPM fan mode stops the fan at low loads
  • Resonant LLC with DC-to-DC topology delivers clean power
  • 400 W ATX output in a compact Flex form factor

Form factor and target use

This 400W Flex ATX unit is built for compact servers, 1U NAS enclosures and small-form-factor workstations where space is tight but reliable power is essential. Its Modern Standby support makes it a good match for systems that spend long periods in low-power sleep states and need near-instant wake response.

Connector and clearance checks

Verify that your chassis accepts a Flex ATX power supply and that the cable harness reaches every motherboard, drive and backplane connector in your layout. Confirm the 24-pin ATX, 4+4-pin CPU and peripheral leads are long enough for your specific board placement before ordering.

Sustained-load behaviour

The 80 PLUS Gold rating and LLC resonant topology with DC-to-DC conversion keep efficiency high and voltage regulation tight during continuous operation. At low and medium loads the Zero RPM fan mode stops the fan completely, while the topology reduces coil whine so acoustic output stays low even when the unit runs for extended periods.

Questions sur cet article

What cables and connectors come with the 400W unit and what must be sourced separately?

The power supply ships with the standard ATX 24-pin, 4+4-pin CPU and peripheral cables fitted; any specialised GPU or storage cables would need to be purchased separately.

How do the ENH-1940 and HK320-93FP designations help me choose the right capacity?

ENH-1940 identifies the 400 watt model, while HK320-93FP and HK250-93FP refer to lower-wattage variants; select the 400 watt version when your build requires the higher output.

What does the 80 PLUS Gold rating mean for day-to-day power draw and heat?

It certifies the unit meets high efficiency targets at typical loads, so the system draws less mains power, runs cooler and the fan can stay off longer in Zero RPM mode.
