## Long description

PREMIUMCORD kn-3 is an internal power adapter cable that converts a single 5.25" drive power connector into two 3.5" drive power connectors. It is intended for use inside desktop PCs and server chassis to provide power to 3.5" hard drives, floppy drives or other internal devices that use the standard 3.5" power plug.
Advantages
The adapter allows powering two 3.5" devices from one 5.25" power outlet, reducing the need to open the power supply or add cables. It is compact, straightforward to install and compatible with standard Molex-style drive power connectors used in many PC and server builds.
Suitable for
 Powering two 3.5" hard drives from a single 5.25" connector
 Connecting floppy drives or other 3.5" devices in desktop PCs
 Server or workstation internal installations where additional drive power is required
Key specifications
 Brand: PREMIUMCORD
 Model / MPN: kn-3
 Function: 5.25" (female) to 2 × 3.5" (male) internal power adapter
 Application: HDD, FDD and other internal 3.5" devices
 EAN: 8592220006457
 Category: PC Internal Cables
How to use
Shut down and unplug the computer before installation. Inside the chassis, connect the 5.25" female end of the PREMIUMCORD kn-3 adapter to the power cable from the power supply. Then attach the two 3.5" male connectors to the power sockets of the internal devices. Ensure connectors are fully seated and route the cable to avoid interfering with fans or moving parts. Reconnect power and start the system to verify device operation.
Usage recommendations
Use this adapter only with compatible standard drive power connectors and within the power supply's capacity. Do not force connectors; if a connector does not fit, verify type and orientation. For systems with high total drive power demand, consider adding a dedicated power cable or replacing the power supply rather than relying on multiple adapters.
