Pros & Cons

Manufacturer description
The Cable Matters 3-Pack Molex to SATA Power Cable solves a specific problem in older builds: your power supply has 4-pin Molex LP4 connectors, but the drive you want to install needs SATA power. Each 6-inch cable runs male Molex to female SATA with straight connectors, short enough to keep clutter out of the drive bays instead of coiling spare slack behind the motherboard tray. You get three cables in the pack, so you can power a boot SSD, a secondary HDD, and an optical drive from one order, or keep spares in the toolkit for repair work. Cable Matters lists tested compatibility with common…

Frequently Asked Questions
Will this let me connect a SATA SSD to an older power supply?
Yes. That is the intended use: it converts a 4-pin Molex LP4 output on a legacy power supply into a SATA power connector. Cable Matters lists Crucial 256GB, Intel 520 Series 120GB, and Kingston 120GB/240GB 2.5-inch SSDs among tested drives.
Which direction does this cable go, Molex to SATA or SATA to Molex?
It is male Molex to female SATA. The Molex end plugs into your power supply's 4-pin LP4 lead, and the SATA end plugs into the drive. It does not work in reverse.
Is 6 inches long enough to reach my drive?
It depends on your layout. Six inches is meant to extend an existing Molex lead the last stretch into a nearby drive bay, not to span the case. If your PSU is bottom-mounted and the drive sits in a top bay, measure from where your Molex lead ends first.
Why does the pack include three cables?
Cable Matters sells it as a 3-pack so you can power multiple drives from one order or keep replacements on hand. It is priced as a spare-and-replacement bundle for DIY builders and repair techs, not as a single-cable purchase.
Does this work with SATA optical drives as well as hard drives?
Yes. Cable Matters lists SATA internal optical drives in its compatibility examples, including a 24x DVD-RS serial-ATA drive and a SATA Supermulti burner, alongside SATA HDDs and SSDs.
