3Port HTPC HDD Power Switch Module, Manual Hard Drive Power Controller for 80mm HalfHeight Chassis Bay, MultiSystem Switching Selector for PC SSD HDD Independent Power OnOff Control

This 3port HDD power switch module is a practical hardware accessory specially designed for HTPC and custom desktop PCs. Installed into a standard 80 mm halfheight drive bay, it provides independent power management for up to three SATA hard drives or solidstate drives.

With physical manual switches on the front panel, users can cut off or restore power to individual hard disks. When multiple operating systems are installed on different drives, this hardwarebased multisystem switching avoids file corruption and crossaccess conflicts caused by simultaneous mounting of multiple system disks. You can activate only one target system drive at a time without complicated BIOS setup.

No software, drivers or extra configuration are necessary. It also helps reduce idle power draw and lowers heat generation by powering down unused storage devices. The robust metal front panel ensures longterm stability during frequent switching operations.

Perfect for multiOS DIY builds, private offline data storage, system testing and HTPC modification work. Please verify your chassis bay size and harddisk power interface before purchase to guarantee compatible installation.
