Need help using molex to power a wireless router. - Overclock.net

Ok so I have this router that I don't have a wall wart for. And I've noticed it needs 5V @ 2 amps and I was wondering could I use 2 wires soldered to the 5v lead on a molex connector to power it?

I know the 5v lead has 2 amps. But how would I ground it ect? The router is a Zyair G-4100-AWP. Thanks!

Buy a universal power adapter at Radio Shack or something, it will save you a lot of trouble.

If I had the money I wouldn't be doing this trust me lol. That and I like soldering.

red is +5V and black is Gnd

Well I got that. I'm not sure though which is positive in the connector on the router and which is ground. Is it the piece that would touch the sleeve or the male part that would go inside the normal connector from the wall. I hope that made sense.

I think the inside of the plug in the middle would be the 5v and the sorrounding outside would be the ground insde the router where the adaptor would plug in. Sounds kinda risky.

oftentimes there is an icon beside the jack (or elsewhere on the device) to indicate the polarity of the power connector

No such luck that was my first hope. I think that's how it would work + being the pointed piece. I will be soldering to the contacts that protrude the underside of the PCB so I can still use a wall wart in the future if I get the funds.

And its an old wireless g router that I got for free so risk doesn't matter its more for fun.. lol

Good luck with that, I hope it works for everyones future reference.

if you're opening it to solder onto the solder pads inside the router, then you might be able to tell which is ground; usually the ground trace covers most of the bare area of the PCB.
