KHACHIMO PSU For Advantech AT 150W Power Supply PS-150 PSA-1509U

SKU CH-GFYG-J8DR9

A new 150 W ATX power supply with 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
  • 80 PLUS Gold certification delivers high efficiency for lower power use
  • Zero RPM fan mode stops the fan at low loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine
  • 150 W ATX power supply built for Advantech PS-150 and PSA-1509U compatibility

150W ATX Power Supply for Advantech Systems

This 150-watt ATX unit replaces the Advantech PS-150 and PSA-1509U models in compatible industrial or embedded PCs. It delivers standard ATX voltages through a compact form factor designed for space-constrained chassis. The power supply is new and built to meet the original equipment specifications. Its 80 PLUS Gold certification ensures efficient conversion across typical load ranges.

Suited for low-power embedded builds

Integrators servicing Advantech platforms that require a direct 150W ATX replacement will find this unit matches the original connector layout and power profile. Builders planning high-performance discrete graphics, multiple storage arrays or heavy CPU workloads should look elsewhere, as the 150-watt limit leaves no headroom for such configurations. Systems needing redundant or hot-swap power modules are also not addressed by this design.

150-watt capacity with Gold-rated efficiency

The 150W rating comfortably handles single-board computers, thin clients and industrial controllers with modest CPU and I/O demands. Zero RPM fan mode keeps acoustics near zero during light office or kiosk workloads, while LLC resonant topology with DC-to-DC conversion maintains tight voltage regulation. Sustained loads approaching the 150-watt ceiling will spin the fan and reduce efficiency margins, so continuous maximum draw is not recommended.

Questions about this item

Does my motherboard need a standard ATX power connector to use this 150W supply?

Yes, the unit follows the ATX form factor so it connects to any motherboard with a 24-pin ATX socket and matching CPU power headers.

Will the Zero RPM fan mode still activate if I pair this PSU with an older platform that lacks Modern Standby support?

Yes, Zero RPM mode relies on internal load sensing and functions independently of the motherboard sleep-state capabilities.

How can I confirm the 80 PLUS Gold efficiency is being achieved after installation?

Monitor AC wall draw versus DC output with a power meter; at typical loads the unit should exceed 80% efficiency, matching the Gold rating.
