Pros & Cons

Pros

  • ✓ Three cables per pack covers a full multi-drive build or a tech's spares kit
  • ✓ Full 3.3V / 5V / 12V rail set, so SSDs and optical drives both power normally
  • ✓ 8-inch length adds reach without leaving slack to hide behind the drive cage
  • ✓ Extends the existing PSU lead instead of replacing it, cutting connector bend stress

Cons

  • ✗ 8 inches only - no help if the drive bay is a foot from the PSU
  • ✗ Extension adds a second connection point where a marginal contact can appear
  • ✗ Male-to-female extension, so it cannot split one PSU lead to two drives
  • ✗ Three identical lengths, no mixed-length option for varied bay distances

Manufacturer description

The Cable Matters 3-Pack 15-Pin SATA Power Extension Cable solves a problem every builder hits eventually: a PSU cable that stops two inches short of the drive bay. Each 8-inch extension bridges the gap between your existing power supply connector and any SATA device, whether that's a mechanical HDD, a 2.5-inch SSD, or an optical drive in a retro tower. Because you're extending rather than replacing, you keep the PSU's original run intact and take the bend stress off tight motherboard-adjacent connections. The 8-inch length is deliberately short. It gives you enough slack to reposition a…

Frequently Asked Questions

Will this work with SATA SSDs, not just hard drives?

Yes. It carries the full 3.3V / 5V / 12V SATA power rail set, so 2.5-inch SSDs, 3.5-inch HDDs, and optical drives all receive the same power as a direct PSU connection.

How long is each cable, and is 8 inches enough?

Each of the three cables is 8 inches. That covers repositioning a connector across a drive cage or reaching one bay further, but not long runs from a bottom-mounted PSU to a top 5.25-inch bay.

Does it split one PSU connector into multiple drives?

No. This is a straight extension - one SATA power input to one SATA power output. The three-pack gives you three separate extensions, not a splitter.

Why would I need an extension instead of a longer PSU cable?

Extensions let you keep the PSU's stock cabling and avoid forcing a tight bend at the motherboard or PSU end. Cable Matters designs this specifically to relieve that strain while keeping internal routing clean.

Is it covered by a warranty?

Cable Matters publishes warranty terms per product, so check the current Amazon listing for the coverage and support details that apply to this 3-pack.
