KHACHIMO

KHACHIMO ACE-4518AP 180W ATX Power Supply

SKU CH-KVTB-TSRY9

An 180 W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and resonant LLC topology for silent, efficient operation

  • TypeATX
  • Modern Standby compatible for near-instant wake from sleep
  • 80 PLUS Gold certified 180 W ATX supply cuts power draw and heat
  • Zero RPM fan mode stops the fan at low and medium loads for silent running
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine
  • Compact 1U form factor fits space-constrained builds

Compact 1U ATX Power Supply

The KHACHIMO ACE-4518AP delivers 180W of continuous power in a 1U form factor designed for space-constrained chassis. It targets system integrators and builders assembling compact workstations, thin clients, or embedded appliances where standard ATX units will not fit.

Modern Standby and Zero RPM Benefits

Modern Standby compatibility enables extremely fast wake-from-sleep transitions while improving low-load efficiency. Zero RPM fan mode stops the cooling fan entirely at low and medium loads, providing near-silent operation during idle and light workloads.

Gold Efficiency and Resonant LLC Topology

80 PLUS Gold certification ensures high efficiency operation, reducing power consumption, noise, and operating temperatures. Resonant LLC topology with DC-to-DC conversion supplies clean, consistent power, minimises coil whine, and supports more energy-efficient sleep states.

Questions about this item

Will the fan on the ACE-4518AP need cleaning or replacement after long use?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, reducing wear and dust build-up; if it ever needs service the 1U form factor allows straightforward access.

What limit appears first when the ACE-4518AP runs at full load continuously?

The 180 W rating is the hard ceiling; sustained draw at that level will hit the power limit before thermal protection activates.

How much noise and heat does the ACE-4518AP produce during all-day operation?

80 PLUS Gold efficiency and the resonant LLC topology keep waste heat low, while Zero RPM mode silences the fan at typical loads.
