This one http://www.amazon.com/gp/product/B00J3MHTYG?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00 works good and has a lot better reviews than that one. I'm going to get me another one to do my whole battery less setup with them. The 10amp is probably just a little over kill but ol well it works.lol
Get a power supply (# of watts) to handle all of your LED strips. If your LED strip is 5V 3A, you need a 15W power supply for just 1 LED strip. I would get large enough 5V power supply to handle all of your LED strips like this one: https://amazon.com/PHEVOS-Universal-Switching-Raspberry-Computer/dp/B074YHN8D1?th=1
I am already using 360W 12V power supply for my solenoids, so I use 5v step downs for my LED strips: https://amazon.com/gp/product/B00J3MHTYG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
