Hello,
I need to create a 24V power supply that can deliver 20A (on a 1.2 Ohm resistor) minimum. I have 4 identical power supplies.
The problem is that I don't know if I can connect them in parallel. If so, should I do it before or after the series?
Similarly, I am counting on a base of 17A at 12V for one power supply. Will I therefore have 24V and 34A when the 4 are connected?
Thank you for your responses!!

Hello,
I need to create a 24V power supply capable of delivering at least 20A (across a 1.2 Ohm resistor). I have 4 identical power supplies.
The problem is that I'm not sure if I can connect them in parallel. If so, should I do it before or after the series?
Did you forget to tell us something??? Are you talking about a TV series? If I were you, I would watch the series first.
So will I have 24V and 34A when the 4 are connected?
It depends on your 4 batteries that you haven't mentioned...

Hello,
your power supplies are technically speaking voltage generators (+12V, +5V...)
you should never connect voltage generators in parallel:
the slightest voltage difference between the two will generate a strong current from one to the other, which can be destructive...
I have 4 PC power supplies 250w
these are probably "no-name" PSUs recovered from old PCs, in my opinion, they're good for the trash :)

With 4 batteries of 1.5V, you'll never get what you want, no matter the configuration.
12V --> 17A
well, there’s also 5 volts and everything, but I don't think I’ll need that.
