Manufacturer description
The Pienmor SATA to 4-Pin power adapter solves one of the most common problems in retro PC building: modern power supplies ship with SATA connectors, while IDE hard drives, older optical drives, and vintage case fans still expect a Molex LP4 plug. This 3-pack gives you a SATA 15-pin male input and a 4-pin Molex LP4 female output on a 7-inch cable, so you can run legacy drives from a current PSU without swapping the whole power supply or hunting down a period-correct unit. The 7-inch length is short by design. It reaches from a modern PSU's SATA lead to a drive bay or fan header without…

Frequently Asked Questions
Will this let me run an old IDE hard drive on a modern power supply?
Yes. That is the stated use case: the SATA 15-pin male end plugs into your PSU's SATA power lead, and the 4-pin Molex LP4 female end accepts the power connector on an IDE hard drive or older optical drive.
How long is the cable?
Each adapter is 7 inches. That is enough to bridge a SATA lead to a nearby drive bay or fan, but plan an extension if your PSU is bottom-mounted and the drive sits at the top of the case.
How many adapters come in the package?
Three. That covers a typical retro build with an IDE boot drive and an optical drive, with one left over for a Molex-powered case fan or add-in card.
Which direction does this adapter go?
SATA in, Molex out. The SATA 15-pin end is male and connects to your power supply; the 4-pin Molex LP4 end is female and connects to the legacy device. It does not convert Molex to SATA.
