I'm currently setting up my case and connecting all the cables to the motherboard headers. I found an unlabeled SATA connector that's bundled with some other cables, one of which is labeled as ARGB input. I'm wondering what this connector is meant for and if I need to plug it into the motherboard or somewhere else? Here's a link to an image of the connector: [imgur link](https://imgur.com/a/lAk1llS).

If your case has a lot of lighting, that SATA connector is probably for power since the motherboard might not provide enough. So, you’d usually connect it to the SATA power from your power supply.
Yeah, I’d go with the others. It’s not for the motherboard; it connects to the PSU. LEDs usually need more power than what the motherboard headers can provide.
That SATA connector is likely for powering your case fans or lighting. It should connect to your power supply instead of the motherboard. Check if your case has a fan controller or hub that needs extra power!
Also, do you have an AIO cooler for your CPU or GPU? If so, that SATA cable from your power supply is where this connector goes, just like your HDDs and SSDs.
I don't think it's connected to a hub, but here's where mine is connected: [imgur link](https://imgur.com/a/otDdAp4). Maybe that helps!
