Manufacturer description
The StarTech.com LP4SATAFM12 SATA to LP4 power adapter cable solves a problem every modern build eventually hits: your power supply is loaded with SATA connectors, but the drive, optical unit, or add-in card you need to power still uses a 4-pin Molex plug. This 12-inch adapter bridges that gap, pulling power from an available SATA connector on your PSU and delivering it to any LP4 Molex device - hard drives, DVD-ROM drives, expansion cards, and case fans among them. The 12-inch length is the practical detail here. It gives you enough slack to route around a motherboard tray or reach a drive…
