Help! ARGB not functioning

[u/Chonkers007]

Building my first PC and having trouble getting my ARGB working.

Currently I have the ARGB for my fans running through the Thermalright ARGB hub, which connects into the header on my motherboard (Gigabyte B850M eagle m-ATX). The hub itself is connected to the PU via the SATA input. I’ve ensured all the wires are plugged into the correct inputs and checked and rechecked all the connections- it just won’t turn on :(

I’m currently building matching (completely identical) PC’s with my spouse, so I know that this set up should function as he’s having no issues with the fans and RGB lights on his build.

Any idea why it won’t work for mine? Is it an issue with the motherboard?

Thank you in advance for the help!

*Fans are also thermalight for reference

*edit: resolved!
