Power multiple SBCs
-
Hi all, I have 4 single board computers each with its own power supply - I would like to have a single power supply power them all ( they have a USB C power input socket ) Despite googling I can't find anything - any of you gurus know a way ( I can't use POE as I can't get a cable to where they are ) I magine something like a powered USB hub with C outlets

could you use a 24v psu, and hook 4 adjustable power bucks up to it, and power the SBCs from that? I don't think a powered USB hub would provide enough power (1-2 amps at the most, and a raspberry pi (for instance) needs three amps for power.

When you pry the gun from my cold dead hands, be careful - the barrel will be very hot. - JSOP, 2013 -

Hi John, not familiar with power bucks I'll check them out

Getting a bit out of my depth here methinks - how would i connect 4 of them to a power supply and then out to my boards ?

run wires from the psu to the power bucks, and then run cables from the bucks to the Pis. Your other option is a UPS and plug all the pis's into it. That's much more expensive, but you get the highly valuable added protection of the UPS. I have an 1100ma UPS dedicated to a bank of six Pi's.

What do you use your Pi's for ? I've used one for years coupled with a £35 DAC hat from hifiberry to stream my digital files to my analog amplifier - it has no right to sound as good as it does. I also have a £1500+ DAC and while it's better quality - it certainly isn't £1465 different. Can you send a link for the UPS ?

A database server for my three home theater boxes (also Pi's), three DNS servers (using PiHole), and a controller for my 3D printer. One pi is simply a spare in case one of the other ones fail. I have a crapload of Pi's (all are Pi4). They're smaller and more economical than a full-blown PC, and can be fully outfitted for less than $100 (each):)

Do you have your Pi's in a cluster ?

No, but if I werent so old, I’d explore that.
