KHACHIMO FSP -5V 1U 500W Switching Power Supply FSP500-80BU

SKU CH-ZARZ-FA8WW

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

  • TypeATX
  • Fast wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency reduces power draw and heat
  • Fan stops at low loads for silent operation
  • Resonant LLC topology delivers clean, stable power
  • DC-to-DC conversion enables efficient sleep states

Modern Standby PSU for fast wake systems

The KHACHIMO FSP500-80BU is a new 500W ATX power supply built for Modern Standby compatible platforms. It delivers extremely fast wake-from-sleep times and improved low-load efficiency. This unit suits builders who need reliable power for systems that spend long periods in low-power states.

Sustained load efficiency and quiet cooling

Certified 80 PLUS Gold, the supply maintains high efficiency across typical workloads, reducing power draw, heat output and fan noise. Its Zero RPM fan mode keeps the cooling fan off entirely at low and medium loads for near-silent operation. Under sustained demand the resonant LLC topology with DC-to-DC conversion provides clean, consistent power while minimising coil whine.

Compact 1U build with standard ATX fit

The 1U form factor allows installation in slim chassis or rackmount enclosures where vertical space is limited. Standard ATX dimensions ensure compatibility with common mounting points and cable routing. Builders needing multiple GPU power connectors or very high wattage headroom should look elsewhere, as this unit targets efficient single-GPU or integrated-graphics configurations.

商品問答

How much fan noise and heat does the FSP500-80BU produce under continuous load?

The 80 PLUS Gold certification means high efficiency, so less waste heat and lower fan speeds. Zero RPM Fan Mode stops the fan completely at low and medium loads for silent running.

What components must I already have to install this 500W ATX power supply?

You need an ATX-compatible case and motherboard with standard 24-pin and CPU power connectors. The unit follows the ATX form factor, so it fits existing mounting points and cable routing.

Will the FSP500-80BU work reliably with older hardware I plan to keep?

Resonant LLC topology with DC-to-DC conversion delivers clean, stable voltage rails that older components require, while Modern Standby support adds compatibility with newer low-power sleep states.
