Homemade RGB controller

Hi I was wondering, it looks like it is powered by sata, am I correct? Also if I build this will I be able to plug into the addressable led header on my mobo. What I want to do is connect all my fans this way but I bought some cheep ones that dont have a great controler and I want to run all of them by either a led controler, your SW, or mobo SW. Awesome job either way!

7 Tips On How To Make Your PCB Entries Stand Out 1.Choose the appropriate color of soldermask and silkscreen for your PCB project. 2.In addition to the PCB images generated by our website, you can upload more photos of the project. 3.The more detailed project’s description is, the better judges and other makers understand it. FYI, it is a good idea to insert a video, currently our platform supports “YouTube” and “Vimeo”. 4.Open for Gerber download and BOM download. 5.Frequently share your entries to your social media and some open source forums, allowing more people to vote your entry, like it, download the Gerber file and also place orders for your work. 6.After uploading your entry, please constantly pay attention to its page. There will be other makers asking questions about your PCB project, and timely responses and multiple interactions will be additional points. 7.We also encourage you to upload more entries about Assistive Technology (AT) by supporting a special award, “AT Maker Prize”. Hope that more makers could contribute to the promotion of Assistive Technology.
