SMUGDESK 2 Set ATX 24Pin to 18Pin & 8Pin to 12Pin Cable Kit for HP Z440 Z640

SKU CH-YNS6-CPK56

Two cable sets adapt standard ATX power supplies to HP Z440 and Z640 motherboards with lockable connectors

  • Converts standard ATX 24Pin to proprietary 18Pin motherboard header
  • Adapts 8Pin PSU output to 12Pin workstation auxiliary socket
  • Locking buckles keep connectors secure under continuous heavy load
  • Two complete cable kits simplify dual workstation upgrades or spares
  • Copper conductors minimise voltage drop for stable power delivery

HP Workstation Power Conversion Kit

This cable kit adapts standard ATX power supplies for HP Z440 and Z640 motherboards. It contains two complete sets of conversion cables for maintenance or PSU replacement. Each set provides the connectors needed to bridge proprietary and industry-standard interfaces. The product is built for hardware upgrades and DIY modifications on these specific workstations.

24Pin to 18Pin and 8Pin to 12Pin Pin Mapping

The single specification that decides fit is the exact pin definition matching HP Z440 and Z640 motherboards. Cables convert a 24-pin ATX main connector to the 18-pin board header and an 8-pin ATX auxiliary to the 12-pin board header. Accurate internal wiring ensures safe and stable power transmission. Using this kit on any other motherboard model risks hardware damage.

Locking Connectors for Continuous Operation

Lockable plug buckles maintain tight contact during long periods of continuous operation. High-conductivity copper wires reduce voltage loss under sustained heavy load. The design prevents loose connections and accidental power cuts while the workstation runs demanding tasks. Reliability is maintained through extended uptime rather than short bursts.

Questions about this item

What does the 24-pin to 18-pin cable actually do inside my Z440?

It converts a standard ATX 24-pin main power connector to the proprietary 18-pin socket on the HP Z440 or Z640 motherboard, letting you run an aftermarket PSU.

Does the 8-pin to 12-pin cable limit how much power the CPU can draw?

The cable passes the ATX 8-pin EPS supply through to the board's 12-pin auxiliary socket; the PSU's own rating still sets the practical ceiling.

How much room do I need behind the motherboard tray for these plugs?

Each connector has a locking buckle that adds a few millimetres of depth, so allow extra clearance for the latch to engage fully.
