Key Features

  • 1. Precisely engineered for HP Z-series workstations, this power supply adapter is specifically designed for HP Z620 and Z420 motherboards. It seamlessly converts the standard 24-pin connector of a conventional ATX power supply into the 18-pin power connector required by workstations. Compatible with HP Z220/Z230 (not compatible with Z210), it resolves the challenge of power supply adaptation for workstations.
  • 2. High-specification durable cables feature 18AWG solid copper tinned-copper conductors, supporting 400W high-power delivery. With anti-oxidation properties and low resistance, the 30cm length facilitates optimal chassis routing, meeting the long-term stable operation requirements of HP Z620/Z420 workstations.
  • 3. Plug-and-play design requires no modifications or additional tools/technical expertise. Simply connect the ATX power supply's 24-pin connector to the HP Z420 motherboard's 18-pin interface. Pairing with the original power supply's 8-pin CPU power cable enables normal boot-up, offering novice-friendly installation.
  • 4. Stable compatibility across multiple scenarios, compatible with mainstream ATX power supplies (ATX 2.0 and above). Suitable for upgrading or replacing power supplies in HP Z620 workstations, and also supports power supply expansion for select HP Z series desktop computers, offering high versatility.
  • 5. Safe, reliable and long-lasting cables with flame-retardant insulation, featuring precision injection-moulded connectors for secure, wobble-free plugging and unplugging. Tested for voltage/current stability to provide safe power delivery for HP Z620/Z420 motherboards.
