You're planning a custom build and are connecting rainbow puke to the ARGB headers. The B550 AORUS PRO AC supports up to 5A per header according to its manual. I double-checked the specs and found it matches what you expected. No surprises there! Link to the manual confirms this detail.
The calculations work out correctly. 1000 LEDs operating at 5A each, with a 5V supply. The 2A header can accommodate up to 200 LEDs.
Wow, this seems unusual. Is it typical for Gigabyte boards or are you seeing something rare? It doesn’t look like a top-end model priced at $200.
