KHACHIMO PSM-6600PE 600W ATX power supply unit in metal casing with cooling fan

KHACHIMO

KHACHIMO PSM-6600PE 600W ATX power supply

SKU CH-DXCT-DVNMS

An 80 PLUS Gold 600 W ATX unit with Modern Standby support, zero-RPM fan mode and resonant LLC plus DC-to-DC topology for clean, quiet power

  • TypeATX
  • Fast wake-from-sleep with Modern Standby support
  • Lower power draw and heat via 80 PLUS Gold efficiency
  • Silent low-load operation with Zero RPM fan mode
  • Clean, stable power from resonant LLC with DC-to-DC conversion
  • 600 W ATX capacity for reliable system delivery

4U 600W ATX power supply for rack systems

The KHACHIMO PSM-6600PE is a 4U form-factor ATX power supply rated at 600W. It fits rackmount chassis and industrial enclosures that require the taller 4U height. The unit targets builders who need reliable power delivery in server or workstation cases where standard PS/2 units cannot be installed.

80 PLUS Gold certification and Zero RPM fan mode

The 80 PLUS Gold rating means the supply meets high efficiency targets across typical loads, reducing waste heat and lowering electricity draw. Zero RPM fan mode stops the cooling fan completely at low and medium loads, eliminating fan noise during idle or light work. Resonant LLC topology with DC-to-DC conversion delivers tight voltage regulation and helps suppress coil whine.

Modern Standby support for fast wake

Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency, suiting systems that frequently enter and exit low-power states. Builders using standard ATX desktop cases or compact small-form-factor enclosures should look elsewhere, as the 4U height prevents installation in those chassis. Systems requiring power above 600W also need a higher-capacity unit.

Highlights

  • Fast wake-from-sleep with Modern Standby support
  • Lower power draw and heat via 80 PLUS Gold efficiency
  • Silent low-load operation with Zero RPM fan mode
  • Clean, stable power from resonant LLC with DC-to-DC conversion
  • 600 W ATX capacity for reliable system delivery

Questions about this item

How often will the internal fan need replacement under continuous 600W load?

The 80 PLUS Gold certification and Zero RPM Fan Mode reduce fan runtime, so the fan typically lasts the unit's full service life without scheduled replacement.

Which protection triggers first when the PSM-6600PE runs at maximum output for hours?

Over-temperature protection engages before any voltage rail exceeds its limit, throttling output to keep components within safe thermal margins.

How loud and hot does the PSM-6600PE get during an all-day workload?

At low and medium loads the fan stays off for near-silent operation; under sustained high load the fan spins up, but 80 PLUS Gold efficiency keeps waste heat and noise lower than non-certified units.
