Cable Matters 3-Pack 15-Pin SATA Power Y-Splitter

Bottom line: The Cable Matters 3-Pack 15-Pin SATA Power Y-Splitter: Three 8-inch Y-splitters per pack, not one - spares for future builds or IT repair kits; main trade-off: 8 inches is short for full-tower routing from a bottom-mounted PSU.

Pros & Cons

Pros

  • ✓ Three 8-inch Y-splitters per pack, not one - spares for future builds or IT repair kits
  • ✓ One male 15-pin input feeds two female SATA outputs from a single PSU lead
  • ✓ Carries 3.3V, 5V and 12V rails, so SATA I/II/III drives all work
  • ✓ Channel-guide connectors seat snugly and resist accidental disconnection

Cons

  • ✗ 8 inches is short for full-tower routing from a bottom-mounted PSU
  • ✗ Splitting does not add PSU headroom - the source rail still limits total draw
  • ✗ 15-pin SATA only; no Molex-to-SATA or SATA-to-Molex conversion
  • ✗ Fixed Y shape offers no daisy-chain option for a third drive
