Silver ATX power supply unit with cooling fan and cable bundle

KHACHIMO

KHACHIMO YKD-6300DC24 ATX 24V 300W 80 PLUS Gold power supply

SKU CH-VG61-QERGV

A 24V ATX unit delivering 300W with 80 PLUS Gold efficiency, zero-RPM fan mode and LLC resonant topology for quiet, low-load operation

  • TypeATX
  • Fast wake from sleep with Modern Standby support
  • 80 PLUS Gold efficiency reduces power draw and heat
  • Fan stops at low load for silent running
  • Resonant LLC with DC-to-DC gives clean stable power
  • Replaces ACE-828C, ACE-925C, ACE-920C, ACE-935C

Direct Replacement Targets

This unit is built to replace the ACE-828C, ACE-828C-RS, ACE-925C, ACE-920C, and ACE-935C models directly. The upgrade is worth it when the existing supply lacks Modern Standby support or 80 PLUS Gold efficiency ratings.

80 PLUS Gold Efficiency and Quiet Operation

Certified 80 PLUS Gold operation reduces power consumption, noise, and heat output. Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running, while resonant LLC topology with DC-to-DC conversion minimises coil whine.

Modern Standby Builds and Legacy Swaps

Ideal for builders needing fast wake-from-sleep times and better low-load efficiency in Modern Standby systems. Not suited for systems requiring higher wattage output or different voltage rails than the 24V 300W design provides.

Highlights

  • Fan stops at low load for silent running
  • Resonant LLC with DC-to-DC gives clean stable power
  • Replaces ACE-828C, ACE-925C, ACE-920C, ACE-935C

Questions about this item

What physical space and mounting does the ATX form factor require?

The ATX form factor fits standard ATX case openings and uses four rear mounting screws.

How is the YKD-6300DC24 installed and which step is often missed?

Mount the unit, connect the 24 V DC input, attach the ATX motherboard and peripheral cables, then verify Modern Standby is enabled in BIOS for fast wake.

What maintenance will the 80 PLUS Gold unit need over time?

Clean dust from the fan and vents periodically; the Zero RPM mode reduces wear, so the fan typically lasts years before replacement.
