Pros & Cons

Pros

  • ✓ Turns one PSU SATA port into 4 outputs for HDDs, SSDs, or optical drives
  • ✓ 2-pack expands two PSU ports, so you cover 8 drives per purchase
  • ✓ 18AWG conductors carry full 3.3V, 5V, and 12V rails
  • ✓ 4.5-inch receptacle spacing matches typical drive-cage stacking

Cons

  • ✗ 18 inches total may not reach top-mounted drive bays in full towers
  • ✗ Splitting one PSU rail four ways limits total draw per connector
  • ✗ No right-angle connectors for tight side-panel clearance
  • ✗ Fixed 4.5-inch spacing is awkward for scattered drive positions

Manufacturer description

The Cable Matters 2-Pack SATA Power Splitter solves a problem every dense build eventually hits: your PSU has run out of SATA power leads. Each cable turns one 15-pin SATA output into four, so a single PSU port can feed four HDDs, SSDs, optical drives, or PCI-E devices — and with two cables in the pack, you can expand two ports at once. The 18-inch harness spaces its four drive receptacles at 4.5-inch intervals, which lines up with typical drive-cage stacking and keeps the run tidy instead of pooling slack behind the motherboard tray. Flexible 18AWG conductors carry the full 3.3V, 5V, and…

SpecPicks Verdict

Frequently Asked Questions

How many drives can one Cable Matters SATA splitter power?

Each cable splits a single 15-pin PSU SATA output into four receptacles, so one cable powers up to four HDDs, SSDs, optical drives, or PCI-E devices. The 2-pack covers eight total across two PSU ports.

How long is the cable?

The harness is 18 inches, with the four drive receptacles spaced at 4.5-inch intervals along the run.

What gauge wire does it use, and does that matter?

It uses 18AWG conductors. Heavier gauge keeps voltage drop low across the 3.3V, 5V, and 12V rails when you are feeding four devices from one PSU lead.

Will it work with SATA III SSDs?

Yes. Cable Matters lists compatibility with SATA I, II, and III devices, and it connects to standard PSU SATA outputs.

Is this a good alternative to buying a bigger power supply?

If you are only short on connectors rather than wattage, yes. It expands the SATA outputs your existing PSU already has. If your total draw exceeds the PSU's rating, you still need a larger unit.
