KHACHIMO PSU For FSP 1U 500W Power Supply FSP500-60WS1

SKU CH-2G0Y-MA39S

1U 500W ATX power supply with 80 PLUS Gold efficiency, Zero RPM fan mode and Modern Standby support

  • TypeATX
  • Faster wake-from-sleep with Modern Standby support
  • Lower power draw via 80 PLUS Gold efficiency
  • Near-silent operation through Zero RPM fan mode
  • Cleaner power delivery using resonant LLC with DC-to-DC
  • Reduced coil whine for quieter system operation

500 W 1U Power Supply

This new ATX power supply delivers 500 watts from a 1U form factor. It is built for rackmount servers and compact workstations that require efficient, reliable power in a single rack-unit height. The unit carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep transitions.

Suited for dense rack builds.

The 1U chassis targets system integrators populating shallow rack cabinets or blade enclosures where vertical space is at a premium. Its zero-RPM fan mode keeps acoustic output near zero at low and medium loads. Builders assembling standard ATX tower systems should look at full-size units instead.

80 PLUS Gold efficiency with LLC resonant topology

The resonant LLC design paired with DC-to-DC conversion delivers clean, stable voltages while minimising coil whine. Gold-level efficiency reduces waste heat and lowers operating costs across the load range. This topology also enables deeper, more energy-efficient sleep states supported by Modern Standby.

商品問答

How do I fit this 1U ATX unit into my server chassis and what step is often missed?

Slide the unit into the 1U bay, secure the four mounting screws, then connect the 24-pin ATX, 8-pin EPS and any PCIe cables; the step most installers miss is plugging the 8-pin EPS connector because it sits beside the main plug and looks identical.

Which part will need attention or replacement after extended use?

The cooling fan is the only mechanical component; dust buildup on its blades and bearings is the first thing that degrades performance, so plan to clean or replace the fan assembly when noise or speed warnings appear.

What limit appears first when the supply runs at high load for long periods?

Thermal protection engages once internal temperatures exceed the design ceiling, causing the fan to ramp to maximum speed and, if heat continues to rise, a controlled shutdown to protect the resonant LLC and DC-to-DC circuitry.
