They typically convert a single LP4 (4‑pin Molex) or a 15‑pin male power connector into two SATA 15‑pin female power connectors, allowing one power feed to supply two SATA devices.
Most splitters turn one power connector into two SATA power ports, allowing a single feed to power two drives or SATA devices.
They are compatible with devices that use a 15‑pin SATA power connector, such as SATA hard drives (HDDs), solid‑state drives (SSDs), optical drives, and other SATA‑powered components.
They are typically male‑to‑female adapters: a single male power connector is converted into two female SATA power ports for downstream devices.
Weights shown in the listings range from about 0.05 to 0.08 pounds.
They are described as plug‑and‑play with no drivers required—simply plug the splitter into the power supply and connect your SATA devices for straightforward installation.
