Hello everyone.

 

I was wondering if it is possible to power these LED's with a PSU from my computer with Molex.

Thanks

Assuming the voltage on the connectors lines up (remember, the MOLEX connector has +5V, +12V and 2 grounds), I don't see any reason why not.

 

I currently have my DSL modem, my router, and a few other items running off the 12V power lead from an old PSU.

no!!! not if i'm understanding the question correctly and you want to just plug the 4 pin led strip connection into a molex plug.

 

the 4 connections that plug into the controller box lead are not like a molex plug connections, there is probably a single ground and then the 3 other wires are separate +12v control wires for each of the separate colour leds in the strip, leds only need a single + and - connection to work.

 

can you power the control box by connecting it to a molex plug then yes probably, it looks like that doesn't come with it's own power supply and you need to supply your own with 12v 24watt capability.

 

so wiring a molex plug to a power jack to be connected to the control box should work yes. molex connection 12v can handle over 100watts.

just make sure you connect the + and - of the jack correctly to orientation the controller box needs, eg, yellow +12v to centre pin of jack, black ground to outer - connection if that is what the controller box says, then the strip plugs into the 4 pin lead from the control box and everything should work.

personally i'd test it on a psu that is not in use by anything just in case, wouldn't want to see you fry your whole pc testing it.

 

eg. something like this
