BUCIER 4 Pin IDE Y Splitter Cable 23cm 2 pcs

Power-splitter for legacy drives

The BUCIER 4 Pin IDE Y Splitter cable turns a single Molex connector into two female ports so older hard disks, optical drives or case fans can share one power lead. Each pack contains two 23 cm cables built with 18 AWG tinned copper wire and PVC insulation for stable current delivery. The plug-and-play design needs no tools or configuration, making it a quick fix for systems that have run out of four-pin power sockets. Ideal for maintaining or expanding legacy desktop builds.

Builders with free Molex headers

Suits anyone adding a second IDE drive, a DVD-ROM or extra cooling fans to a power supply that still offers Molex outputs but lacks enough connectors. Not intended for SATA-only power supplies or for devices that require keyed SATA power plugs, so builders without a spare four-pin header should look at alternative adapter types. The short 23 cm reach also limits use in full-tower cases where drives sit far from the PSU. Choose a longer harness if cable routing distance is a concern.

Steady output under continuous load

The 18 AWG conductors keep voltage drop low when both branches draw power simultaneously, so a hard disk and a fan can spin up together without tripping the PSU protection. PVC jacketing resists heat from nearby components and remains flexible during repeated drive swaps. Because the splitter simply passes through the rail current, sustained performance matches the host power supply’s own rating rather than adding any bottleneck. Reliable for always-on servers or workstations running legacy storage arrays.
