  • TypeATX
  • 80 PLUS Gold certification reduces power draw and heat
  • Zero RPM fan mode stops the fan at low loads for silent running
  • Modern Standby support gives faster wake-from-sleep and better idle efficiency
  • Resonant LLC topology with DC-to-DC conversion supplies clean power and cuts coil whine
  • 550 W output with dual CPU 8-pin connectors fits 1U server builds

KHACHIMO 550W Gold PSU

The KHACHIMO P1H-5550V is a 550W ATX power supply certified to 80 PLUS Gold efficiency. It uses a resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. A zero RPM fan mode stops the cooling fan at low and medium loads for near-silent operation.

Who This Suits and Who Should Look Elsewhere

This unit suits builders needing a Gold-efficient 550W supply with quiet low-load operation and Modern Standby support for fast sleep wake. It is not for systems requiring higher total wattage than 550W or configurations demanding more than two CPU 8-pin connectors. Buyers needing modular cables or additional PCIe power headers for multi-GPU setups should consider other models.

The Spec That Decides Fit

The 550W rated output is the single figure that determines whether this PSU can handle your build. Verify that your complete system power draw stays within this limit before purchasing. The dual CPU 8-pin connectors support dual-processor or high-end single-socket boards. Ensure your case accommodates a standard ATX form factor unit.

Questions sur cet article

Will the P1H-5550V's 80 PLUS Gold efficiency benefit my older components?

The 80 PLUS Gold certification means the unit runs at high efficiency across typical loads, so your existing hardware draws less power from the wall and generates less heat inside the case.

How do I confirm the Zero RPM fan mode is active on the P1H-5550V?

Under light or medium workloads the cooling fan stops completely; you can verify it by listening for silence at idle or watching the fan blades through the vent while the system is under low load.

Does the P1H-5550V include the two CPU 8-pin cables needed for my dual-connector motherboard?

The product title specifies CPU8Pin*2, indicating the unit provides two 8-pin EPS connectors for the motherboard; check the accessory bag for any additional peripheral cables you may need.
