Pros & Cons

Pros

  • ✓ Three adapters per pack — spares on hand for future builds or failed connectors
  • ✓ Powers two SATA drives from one legacy Molex LP4 port
  • ✓ 18 AWG flexible conductors, not thin ribbon wire
  • ✓ 6-inch length routes behind drive cages without excess slack

Cons

  • ✗ 6 inches is short — may not reach drives far from the LP4 lead
  • ✗ Straight SATA connectors only; no right-angle option for tight cases
  • ✗ Splitting one Molex across two drives shares a single 12V supply rail
  • ✗ Molex-to-SATA adapters are a known fire-risk class if poorly made

Manufacturer description

The Cable Matters 3-Pack Molex to Dual SATA Power Y-Cable Adapter solves a problem every retro PC builder and drive upgrader eventually hits: a power supply with plenty of legacy 4-pin Molex LP4 connectors and nowhere near enough SATA power leads. Each 6-inch splitter takes one Molex male connection and breaks it out to two 15-pin SATA female straight connectors, letting you power a pair of SATA hard drives, SSDs, or optical drives from a single LP4 port. The short 6-inch run is deliberate — it keeps slack out of the chassis and routes cleanly behind a drive cage instead of coiling across…

SpecPicks Verdict

SpecPicks scored Cable Matters 3-Pack 4 Pin Molex to Dual SATA Power Y-Cable Adapter… using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies & cables category. Cable Matters's power supplies & cables lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

How many SATA drives can I power with one of these adapters?

Two. Each cable has one 4-pin Molex male input and two 15-pin SATA female straight connectors, so a single LP4 port on your power supply feeds two SATA drives. The 3-pack gives you six SATA power connections total.

How long is the cable?

6 inches. That length is intended for internal cable management — routing from an LP4 lead to a nearby drive cage — rather than spanning the width of a full-tower case. Measure the gap between your power supply's Molex connector and your drive bays before ordering.

Will this work with my SSD and my old power supply?

It is built for 5V SATA devices connecting to 12V ATX supplies. Cable Matters' published compatibility list includes the Crucial 256GB and Intel 520 Series 120GB 2.5-inch SATA SSDs, Kingston Digital 120GB 2.5-inch SSDs, and Antec VP-450W, EVGA 430W, Coolmax 500W, and Cooler Master Elite 460W supplies.

Can I use this for a SATA DVD or optical drive, not just hard drives?

Yes. The listing calls out SATA optical drives specifically, including 24x DVD-RS internal drives and SATA Supermulti burners, alongside internal SSDs and HDDs. Any drive using a standard 15-pin SATA power input applies.

What gauge wire does it use, and is that enough for two drives?

18 AWG flexible conductors, which Cable Matters specifies for connecting two SATA HDDs to a power supply. Check your drives' combined draw against your supply's rail rating for high-power spinning disks.
