gounthar Posted January 7, 2020 Posted January 7, 2020 Hi there, I'm looking for a USB power supply that would be mounted into a rack, so that I can power up quite a few boards at the same time. These boards would also be in the same rack. I found a big rackable USB hub, but that's not what I am looking for, and 2.4A max per slot may be too weak for some of the boards. I could hosts several smaller USB hubs too, but that does not sound really enticing. My other option is to make it by myself with salvaged server power supplies, a patch panel, bits and bobs, but it will take longer... Would you have any recommendation? Thanks.

Perhaps something like this? https://www.pimfg.com/product-detail/POWER-USB-18-RK I doubt you will find more powerful USB hub. Then you will also have a few 12V boards which you have to power separate (or power non-standard way). I "solved" this with having switches and kvm in the rack, but PSU - except 2 x 7 powered USB hub, 1.5A per port. But I don't actually need permanent solution - boards - up to around 25 can be connected/powered at once - are changing all the time. 1
gounthar Posted January 8, 2020 Author Posted January 8, 2020 This one looks better suited to my needs, thanks Igor. Yes, I also have quite a few 12V boards, so I have to figure it out too... I guess I will go the server PSU way. As I am trying to build some kind of farm, the boards have to be powered all at the same time.
Igor Posted March 23, 2020 Posted March 23, 2020 16 x max. 2,1 A per port https://www.reichelt.de/steckdosenleiste-19-16-usb-ladeports-int-164580-p248713.html?&nbc=1
gounthar Posted March 23, 2020 Author Posted March 23, 2020 Not bad, thanks a lot! Too bad I made an order at Reichelt yesterday... It wouldn't fit all my boards because of the 2.1A limitation, but nice for the price!

I know for some I will still need to use something else, but most it will cover. The price is reasonable, yes. ... not working anymore Spoiler 1
