J&D 4 Pin Molex to Dual SATA Power Y-Cable Adapter

Bottom line: The J&D 4 Pin Molex to Dual SATA Power Y-Cable Adapter: Two-pack of LP4-to-dual-SATA splitters powers 4 SATA drives from 2 Molex leads; main trade-off: 8 inch (20cm) length is short for routing to drives in a far cage.

Pros & Cons

Pros

  • ✓ Two-pack of LP4-to-dual-SATA splitters powers 4 SATA drives from 2 Molex leads
  • ✓ 18 AWG oxygen-free copper handles HDD spin-up draw better than thin 20-22 AWG splitters
  • ✓ Latching SATA connectors resist vibration pull-out inside a running case
  • ✓ Skips a PSU upgrade when a legacy supply has Molex but few SATA leads

Cons

  • ✗ 8 inch (20cm) length is short for routing to drives in a far cage
  • ✗ Molex LP4 input caps total draw, so loading four spinning HDDs is risky
  • ✗ Braided shielding adds stiffness that resists tight bends behind a motherboard tray
  • ✗ Only 1-year limited warranty from J&D
