so the question is 24 v or 48v ?

i have a dual pl8 so 48v is fine..the issue is my case fans and usb charger are 24..i can probably get a 48v fan..not sure about the usb charger...

thoughts and recommendations?

does 48v make much of a difference and worth it to overcome the buck/boost?
I've been using a 48v power supply on my DPL8x2 for several years now. The higher the input voltage the less current draw so less heat generated in some areas.

The extra 500W may be helpful in your case depending on your charging needs.

I'm using 48v fans in my case. The DC-DC converters are an options as well as using a small power supply of voltage you need. Something like the Meanwell SGA series:

I'm running a 48-2000 Meanwell in my charging case as well, but powering two dualPL8s. I don't like parallel charging. I'm pushing the limits of the Meanwell, when I charge 4 6s5000 packs at 3c, but the case handles it fine. Doing that at max load (according to the BUMP), it's using approx 1750W.
I usually charge at 2c though.

For my case fans and USB ports, I just used an old wifi router power supply. It was 12V 3A which was all I really needed.
