Common Applications

The Fm-TBYK is a compact inline controller for 5V 3-pin addressable RGB lighting. It draws power from a standard Molex 4-pin connector on the PSU, so it works in builds without a motherboard ARGB header or as a standalone alternative when board software is not available. A button cycles through preset effects and brightness levels, and the controller stores the last selected mode in memory across power cycles. Connect any standard 5V 3-pin A-RGB fan, strip, GPU block, reservoir or fitting to its output. Daisy-chaining is supported up to the load limit of the controller's output.

Frequently Asked Questions

Q: Which devices is the Fm-TBYK compatible with?

A: Any 5V 3-pin addressable RGB device using the standard ARGB pinout (5V / Data / Ground), regardless of brand. AURA Sync ARGB, fans, strips, water blocks and fittings all work.

Q: Will this work with 12V 4-pin RGB devices?

A: No. Connecting 12V 4-pin RGB hardware to this 5V 3-pin controller will damage the LEDs immediately. The two standards are not interchangeable.

Q: Do I need a motherboard ARGB header?

A: No. The Fm-TBYK is powered by a Molex 4-pin connector directly from the PSU and operates fully standalone. It cannot sync to motherboard software.

Q: Does it remember the last mode after a reboot?

A: Yes. The controller has built-in memory and restores the last selected lighting mode after power-off.

Q: How many devices can I chain to one controller?

A: As many as fit within the controller's output current limit. Long ARGB chains may also dim or flicker at the end due to voltage drop, so split heavy loads across multiple controllers or a hub.
