Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

I have about 20 to 30 peripherals on my computers. Each one with its own &%$/&#$% AC power adapter. I really hate these power adapters.

I am thinking of there's some kind of power supply I can buy (similar to those used in electronics) that comes with different voltages (typically +5 -5 +12 -12 +9 -9 and can even supply HP printers +36V if I am not wrong) and I can use to power all peripherals at once. One power supply with wires and plugs to all devices would be a wonderful solution.

Is there something I can buy or adapt to do this?

20 or 30 peripherals? Holy crap. –  MDMarra Sep 11 '10 at 19:25
    
3 computers and a lot of stuff, including a bunch of USB hubs each one with its own (/$(/&#$$ power adapter :( –  SpaceDog Sep 11 '10 at 19:33

OMG, 20-30 peripherals ....hmm GOD Bless You –  subanki Sep 11 '10 at 19:37
    
@subanki - ... each one with its own power ?! –  Rook Sep 11 '10 at 21:14
    
90% of them. Imagine all those creatures reproducing on my floor... I hate them. –  SpaceDog Sep 13 '10 at 2:41

I wish someone would invent some sort of universal DC standard so we could get rid of all those adapters.

The new Universal Charging Solution adopted by the mobile phone industry is a step in the right direction. –  Ken Sep 11 '10 at 20:48

I wouldn't recommend universal adapters, there are some good ones but they are usually more expensive and then you will be wasting a perfectly good one you already have.

Personally, I would suggest you find a good method of organising your current adapters.

I wrap the cord in circles and use reversible/undo-able cable ties, and put stickers on the plugs that say what they are for. This makes them easy to identify and easy to manage without a lot of waste cable.

+1 for properly organizing cables. If you start at home, you'll have a head start if you have to organize a data center ;-). –  sleske Sep 16 '10 at 11:05

Yes, there are "universal" power supplies, with various connectors and switchable output voltage.

One example:

You should be able to get them at any well-stocked electronics supplier.

They are, however, generally more expensive than regular power supplies. Also, you must take care never to set a voltage that is too high for the connected device; otherwise you might fry it.

Also, some devices (e.g. laptops) may need a "smart" power supply, that contains special charging circuitry. These would not work with such a universal power supply. That said, all the laptops I know just have a regular power supply, so that may not be an issue.

Note that even a switchable power supply can only supply one voltage at a time. I don't think there are power supplies with multiple, independent outputs (as they would effectively be two supplies in one box).

the problem with this is that you can only supply one peripheral at a time. I need a box that I can attached zillions of wires and attach all peripherals, so I get rid of thousands of parasitic AC adapters attached to chords and outlets. –  SpaceDog Sep 13 '10 at 2:44
