DC Jacks

zel · 18 Jul 2009 at 15:14

I've got a M1 ATX PSU that I want to use for an Atom System (in the house rather than the car). This board is rated for 90W with a wide input so I can use it with any old laptop supply.

However I'm having trouble finding a DC power jack that is rated for > 5A at 12V.

Anyone know where I can get one? I assume they must exist somewhere since PicoPsu supplies come in ratings up to 150W and have 2.5mm jacks attached!

So your after an AC-DC power brick? well an atom system isnt going to use that much power at all, would have thought a 60w brickm would be fine ?

No the brick is no problem - have a few of these lying around. I'm after the DC jack that the brick plugs into.

What are you intending to connect this do why not buy a pico psu?

I already have an M1 ATX which I'm no longer using in the car - don't want to spend another 50 quid on a picopsu when I've got a perfectly usable psu already - just need a jack!

I could cut the plug off the wall wart and use a different type of connector on both sides but then I'd have to modify the case as well to fit the connector!

What makes a jack able to withstand a higher current? Does the brick output more than 5 amps at 12 volts?

I guess the thickness of the metal?

Yup...
