Our take on the HP 661789-002 20-inch SATA Power Extension Cable

The HP 661789-002 is a 20-inch SATA power extension cable. It lengthens the run between a power supply's SATA connector and a drive or backplane, which helps in tight cases where the standard cable won't reach. It is a plain passive extension with no sleeving or extra features, so it suits builders and repair techs who need reach rather than looks. Rivals add braided sleeves or right-angle ends; this one is a basic OEM-style part.

  • Passive extension with no electronics to fail
  • Simple OEM-style part for repairs and swaps
Cons
  • No sleeving or braiding, so it looks plain in a windowed case
  • Straight connectors only; no right-angle option for tight corners
  • Adds another connection point in the power path
  • Little benefit if your existing cable already reaches

Questions and answers

What does this cable do?
It extends a SATA power connection by 20 inches, letting a power supply reach a drive or backplane that the stock cable can't.
Will it work with any SATA drive?
It uses standard SATA power connectors, so it fits SATA hard drives, SSDs and optical drives that take the usual 15-pin power plug.
Does it affect drive performance?
No. It only carries power; data still runs over your separate SATA data cable.
Can I chain more than one?
You can, but each added connector adds resistance and a possible loose joint. Use the shortest run that reaches.
Is it sleeved?
No. It is a plain cable without braiding or sleeving.
