Recommendations for a Linux and OpenRGB-compatible A-RGB controller.

I have been trying to figure out if i should get a better controller than the onboard controller on my ASRock motherboard.

The only problem is that it doesn't seem to support enough LEDs (or more than 5V/3A which is cutting it close) or direct mode.

I have been looking at the Razer Controller but the supported devices page and old Reddit posts seem to be torn on how good the support is in OpenRGB.

I mostly just need to get a working direct control since the direct control mode currently makes my ASRock motherboard unbootable (temporarily).

Any suggestions are welcome :)
