KHACHIMO 1000W ATX Power Supply 66Pin Gold

SKU CH-0DT7-FWZR4

Delivers 1000W ATX power with 80 PLUS Gold efficiency, a 66-pin connector and zero-RPM fan mode for silent low-load operation

  • TypeATX
  • Modern Standby support for extremely fast wake-from-sleep times
  • 80 PLUS Gold certification for high efficiency and lower power consumption
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine
  • ATX form factor with 66-pin connector fits compatible workstation systems

Compatible Dell Workstation Models

This 1000W ATX power supply replaces units in Dell Precision T5400, T5500, T730, T7400 and T7500 workstations. It matches the 66-pin connector layout used by the H1000E-01, N1000E-01, NPS-1000BB-1 A, UR006 and 0JW123 part numbers. Builders upgrading or repairing these specific systems can install it directly. Buyers with standard ATX motherboards or other proprietary pinouts cannot use this unit.

Pre-Installation Verification

Confirm your workstation is one of the listed Precision models and that the original power supply carries a matching 66-pin connector. Check the chassis clearance for a standard ATX form factor unit before ordering. Ensure the system power requirement does not exceed the 1000W rating. This supply is not suitable for boards using 24-pin ATX or any other connector arrangement.

Sustained-Load Behaviour

The 80 PLUS Gold certification ensures high efficiency during continuous operation, reducing heat output and lowering electricity draw. Resonant LLC topology with DC-to-DC conversion delivers stable voltages under prolonged load while minimising coil whine. Zero RPM fan mode keeps the unit silent at low and medium loads; the fan engages only when thermal conditions demand active cooling. Modern Standby support maintains efficient low-power states during extended idle periods.
