You can buy 12v alternatives on Amazon or Aliexpress, but if you already have those strips might as well use them. I suggest using this calculator and paying attention to the fuse and voltage injection requirements: https://wled-calculator.github.io/ Note also that since you have a dedicated white LED, the default "RGB white" setting (~9A or 3A per color channel) is probably more than you need. An 8A meanwell supply would be a reasonable choice: https://www.amazon.com/MEAN-WELL-original-LPV-60-5-Switching/dp/B06XRZWNJR
