    Default External PSU for multiple devices.

    Ok. Im not sure its the right forum to post this, but i cannot find any other info regarding this topic.

    So i got the following
    1)Creative Soundbalster X7
    2)External USB Hub
    3)Double Charger for PS4 Controllers, and a double charger for XBOX COntrollers.
    4)A HDMI matrix.

    and a few more other stuff.

    All these devices have an external brick that gets plugged in the power in the wall.
    These are their very own PSU. Some are bigger, some are smaller.

    On these PSUs are written the Output Current.
    For instance for the Xbox Controller Charger is 5V 1A.
    FOr my Roccat Apuri (Mouse Bungee with 4 port USB Hub - each port with 2.1A Current) has 5V 2A output current.

    As you can imagine i made it so that i have a lot of plugs to plug stuff.
    I am currently using 15 slots in the power plug sockets. And i still got an incoming Xbox One and probably later on a pair of stand speakers.

    Isnt there a posibility to power all of these devices with a single bigger PSU ?
    From this PSU wire is routed and through special plug in adapters, every devices could be pluged in ?

    I suppose i could look up each and every device and see what its PSU outputs, and i believe a normal PC PSU could power all the stuff up. If it doesnt exceed 12 V since PC PSUs output 3.3, 5 and 12V.

    Why have all the douzen different small PSUs, when you can have only one big PSU, with cabling going to each device !

    Am i the only one who has thought of this ? Hasnt something like this been done yet ?

    For instance the Soundbalter PSU has an output of 24V and 6A, rated for 144W.
    It would be a problem to supply that voltage from a normal PC PSU, or would it ?

    Couldnt you combine two 12V Lines in serial, to get 24V ?

    Something like this would probably be the best solution. Not necessarily that exact one, but the main idea is to get an AC/DC switched-mode dual-output PSU with 24V and 5V rails. You'd then desolder the original power cables from the individual PSUs and connect the wires to the PSU you decide to get.

    Medical PSUs are usually more robust and better regulated (have cleaner outputs) than "ordinary" open-frame or industrial PSUs but they're also quite a bit more expensive.
    Careful what you wish for... You just might get it.

    Medical PSU ?
    This PSU you linked has only two outputs ?

    No. You'd still get +12V.

    Well.. you listed devices that need 24V and devices that need 5V. Why do you need more than two rails?

    You could use +12 V and -12 V pins, but don't expect much power that way. -12 V in ATX PSUs is <1 A.

    This is to complicated !

    I wonder why no PSU maker ever thought of this ?

    FWIW, I'm using a normal ATX power supply with the connectors chopped off to run a bunch of 12V, 5V, and "3-ish"V devices here. I don't have anything 24V, thankfully, but you could always just get a boost converter to convert 12V->24V, have another supply for 24V, or just use the stock adapter if you only have one 24V device.
