I'm ordering a couple of the smaller 150w 8-10a DC-DC buck/boost modules too, that will accept the lower 5v input from the same ATX PSU I'm using.
I'll need 2 of them to split the load from the 5v 20a rail, unfortunately.. I can't find any single 15-20a buck/boost combo modules that accept lower voltages like 3.3 and 5v. Just 6v and up, unless I go with a buck or boost only specific module..
Not sure if the bigger 20a 300w modules will even work with 5v input yet (might try later), but that would be nice if they did, so I could use one single bigger unit like I am on each of the 12v rails.
I'm cool with having a bunch of modules stuffed into an air cooled box anyway, and will have upwards of 5-6 different variable low voltage CC/CV controlled channels for all the different kinds of LEDs/bulbs on my newest rig.

Do you do this to save money or is it for control?
Do you do this because you enjoy building your own?
I’m honestly curious, I have no objection to anything you’ve been doing or have proposed to do. I just haven’t built a powering-unit since I was building my own HPS ballasts.
