Details
The Barrow DK401-7 is a 7-way hub for fans and 5V addressable RGB lighting. Each of its seven six-pin headers carries a fan connection and an LRC 2.0 lighting connection, and the included adapter cable links the hub to a fan header and a 5V ARGB header of your motherboard, so fans and lighting follow the motherboard software.

Seven headers for fans and lighting
Each header has six pins, marked 5V, D1, GND, 12V, FC and PWM: the three lighting lines of Barrow's 5V LRC 2.0 system and the lines of a 4-pin PWM fan. Barrow says the hub connects most Barrow and Barrowch products.
What you can connect
- Barrow LRC 2.0 lighting connectors, fan lighting connectors and the Barrowch water temperature meter with color screen.
- Fans with a 4-pin PWM power connector.
- Barrowch flow meters with a 3-pin, 3-wire connector.
- Barrowch water temperature meters with a 3-pin, 2-wire connector.
Controlled by the motherboard
The 500 mm adapter cable has a 3-pin 5V ARGB plug for the lighting header of the motherboard and a square 4-pin plug for a motherboard fan header. Lighting effects and fan speed then come from the motherboard and its software. The DK401-7 has no remote and no lighting controller of its own; for that, Barrow made the 16-way DK301-16.
Power
The SATA connector powers the hub. Barrow says the hub can also be powered through the adapter cable from the motherboard, but recommends connecting SATA power when you connect many devices.
Mounting
The hub is 6.6 mm thin. Fix it with the adhesive pad on the back (peel off the backing) or with screws.
