Our take on the HP 661789-001 20-inch SATA Power Extension Cable

This is an HP-branded SATA power extension cable, 20 inches long, sold as a replacement or spare part under HP part number 661789-001. It extends the reach between a power supply's SATA connector and a drive or backplane, which matters in tight server and desktop chassis where the stock cable falls short. It is a passive cable with no electronics, so it adds length and nothing else. Buyers should treat it as an OEM-fit part for HP systems rather than a general upgrade.

Pros
  • Genuine HP part number, so it matches HP system documentation
  • 20-inch length reaches drives in larger chassis
  • Passive SATA power extension, no drivers or setup
  • Useful spare for server maintenance kits
Cons
  • Adds cable clutter inside small cases
  • No performance benefit over a standard SATA power cable
  • Only useful if you need extra length or an HP part match

Questions and answers

What does this cable actually do?
It extends a SATA power connection by 20 inches, letting a power supply reach a drive or backplane that the stock cable cannot. It carries power only, not data.
Is it compatible with non-HP systems?
It uses standard SATA power connectors, so it fits most SATA drives and power supplies. The HP part number mainly matters for matching HP service documentation and chassis fit.
Does it affect drive performance?
No. It is a passive extension carrying power, so it does not change data speed or drive behavior.
Do I need this instead of a longer PSU cable?
Only if your existing SATA power lead is too short or you want an HP-marked replacement. A modular PSU with a longer native cable makes it unnecessary.
What is in the box?
The cable itself, as a single HP 661789-001 SATA power extension lead.
