HP Z420 Z620 power adapter

This 24-pin ATX to 18-pin adapter cable lets you connect a standard power supply to HP Z420 and Z620 workstation motherboards. It is built with 18AWG conductors and measures 30 cm in length. The cable is rated for up to 1000 watts of power delivery. It provides a direct replacement link for proprietary HP power connectors.

Replaces proprietary HP power supply

The adapter replaces the need for an original HP power supply unit by converting a standard 24-pin ATX connector to the 18-pin motherboard socket. The upgrade is worth it when the original HP supply fails or when installing a higher-capacity ATX unit. It is not compatible with HP Z210 systems. Buyers needing a longer cable run will need a different solution.

Check motherboard pin count and clearance

Verify that your motherboard uses the 18-pin power connector found on Z420 and Z620 models before ordering. Ensure the 30 cm length reaches from your new ATX power supply to the motherboard socket inside the case. Confirm the 1000-watt rating meets the power draw of your installed components. The package includes only the adapter cable.

Questions about this item

What clearance does the .3 m cable need inside an HP Z420 or Z620 case?

The 30 cm adapter reaches from a standard 24-pin ATX supply to the 18-pin motherboard header without excess slack, so route it clear of CPU coolers and drive cages.

Which orientation do the 24-pin and 18-pin connectors lock in, and what step is often missed?

Both connectors are keyed; press each straight in until the latch clicks, and verify the 18-pin side seats fully on the motherboard before powering on.

When should the 18 AWG adapter be replaced if the system runs near its 1000 W rating?

Inspect the cable annually for discoloured pins or brittle insulation; replace it immediately if any conductor shows heat damage.
