  • TypeATX
  • Modern Standby support for near-instant wake from sleep
  • 80 PLUS Gold certification for lower power draw and cooler running

  • Resonant LLC topology with DC-to-DC conversion delivers clean, stable power
  • 150 W ATX form factor fits compact and standard builds

Compact 150W ATX PSU for Small-Form-Factor Builds

This 150-watt ATX power supply fits the KHACHIMO s5500 and s5800 platforms and replaces FSP150-1Q01, PSR150-A, LSKM2150A, LSPM2150A and PA-1151-3H units. It targets system integrators and upgraders who need a modern, efficient power source for space-constrained desktops or thin-client refreshes.

80 PLUS Gold Replacement for Legacy 150W Units

Swapping an older 150-watt supply for this 80 PLUS Gold model cuts idle draw and thermals, especially when the system uses Modern Standby sleep states. The resonant LLC topology with DC-to-DC conversion delivers tighter voltage regulation and reduces coil whine, making the upgrade worthwhile for noise-sensitive offices or always-on kiosks.

Verify Connector Layout and Chassis Clearance

Confirm that the existing unit’s connector pin-out matches the PA-1151-3H reference and that the chassis can accommodate the ATX form factor. The zero-RPM fan mode only engages at low and medium loads, so sustained high-load scenarios will spin the fan. Ensure the motherboard supports Modern Standby to unlock the fast wake and low-load efficiency benefits.

Questions about this item

What form factor does the KHACHIMO 150W ATX power supply use?

The unit follows the ATX form factor, so it fits standard ATX case openings and mounting holes.

How is the power supply installed in a PC build?

Slide the unit into the case bay, secure it with four screws, then connect the 24-pin ATX, CPU and peripheral cables to the motherboard and components.

When should the cooling fan be checked or replaced?

The Zero RPM mode keeps the fan off at low and medium loads; inspect it if it stays loud under light load or stops spinning under heavy load.
