KHACHIMO FSP180-50PLA 180W ATX Power Supply

SKU CH-T0BW-XNR3Z

An 180W ATX power supply with 80 PLUS Gold efficiency, Zero RPM fan mode and Modern Standby support for compact systems

  • TypeATX
  • Modern Standby support for near-instant wake and better idle efficiency
  • 80 PLUS Gold certified for lower power draw, less noise, cooler running
  • Zero RPM fan mode stops the fan at low and medium loads for silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean, stable power and reduces coil whine
  • 180 W ATX output fits FSP ITX FLEX H128 H129 H110 H128C B85 i3 i5 small 1U NAS builds

Compact ATX supply for thin ITX NAS builds

The KHACHIMO FSP180-50PLA delivers 180 W from an ATX form factor tailored for FSP ITX FLEX chassis such as the H110, H128, H128C and H129. It targets builders assembling low-power NAS or small-form-factor systems based on B85 platforms with i3 or i5 processors where space and efficiency matter more than high-wattage headroom.

Thermals noise and power draw in daily use

80 PLUS Gold certification keeps efficiency high, reducing waste heat and overall power consumption during typical workloads. A Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion supplies clean power, cuts coil whine and supports deeper, more energy-efficient sleep states.

Build integration and system impact

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency for always-ready NAS units. The ATX connector layout fits the listed FSP ITX FLEX models directly, freeing internal volume in 1U and compact enclosures. Buyers needing more than 180 W or additional PCIe power connectors for discrete graphics should look elsewhere.

Questions about this item

How do I install the FSP180-50PLA in a 1U NAS chassis, and what step is often missed?

Mount the unit in the Flex-ATX bay, connect the 24-pin ATX and 4-pin CPU cables, then enable Modern Standby in the BIOS; skipping the BIOS setting prevents fast wake and low-load efficiency.

What maintenance or replacement will this 180W Gold unit need over time?

The Zero RPM fan bears the only moving parts; expect to clean dust from its intake yearly and replace the fan if bearing noise appears after several years of continuous operation.

Which limit appears first when the supply runs near 180W for long periods?

The 80 PLUS Gold efficiency curve drops above 80 % load, so sustained output near 180W raises internal temperatures until the fan spins up, making thermal headroom the practical ceiling.
