Compact silver 1U power supply with 16-pin connector and 150W rating

KHACHIMO

KHACHIMO ACE-816AP-L 1U 16Pin 150W power supply

SKU CH-2WNW-3CVP0

A 1U ATX unit with a 16-pin connector delivering 150W, 80 PLUS Gold efficiency, zero-RPM fan mode and LLC resonant topology for clean, quiet power

  • Product typeATX
  • Modern Standby support enables extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification delivers 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 provides clean, consistent power and reduces coil whine
  • 1U 16-pin 150 W ATX form factor fits compact server and workstation chassis

Compact 1U power supply for space-constrained builds

The KHACHIMO ACE-816AP-L is a 1U form-factor ATX unit rated at 150 W and equipped with a 16-pin connector, making it suitable for slim chassis or rackmount systems where vertical clearance is limited. It is aimed at integrators and enthusiasts building compact workstations or servers that require a standard ATX electrical interface in a low-profile package.

Sustained-load behaviour

Certified to 80 PLUS Gold, the supply maintains high efficiency across typical operating ranges, reducing waste heat and keeping internal temperatures lower during continuous workloads. A resonant LLC topology paired with DC-to-DC conversion delivers clean, consistent power under load while minimising coil whine, and the Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation.

Build quality and connector implications for daily

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency, benefiting systems that spend long periods in idle or sleep states. The single 16-pin output connector simplifies cabling in tight enclosures but limits the unit to platforms designed for that specific pinout, so builders needing multiple peripheral connectors or broader motherboard compatibility should look elsewhere.

Questions about this item

How quiet is the 150 W unit under all-day load?

The 80 PLUS Gold efficiency keeps heat low, and the Zero RPM fan mode stops the fan completely at light and medium loads for near-silent operation.

Which connectors do I already need for the ACE-816AP-L?

It uses a standard ATX 16-pin main power connector, so your motherboard must provide a matching 16-pin socket.

Will the resonant LLC topology work with older components I keep?

The DC-to-DC conversion delivers clean, consistent power compatible with legacy parts, while Modern Standby support enables efficient sleep states on newer platforms.
