How do I connect this?

post #1 of 7
Thread Starter 
Hi all,

I just got an LED kit I ordered from China.

I'm not quite sure how to connect this to molex, so your help would be greatly appreciated.

As you can see there is an adapter with 1 red and 1 black wires sticking out.



Here you can see the IR sensor for the remote, and the LED pins sticking out on the other side.




Any help would be appreciated. Thanks a lot!

p.s.

It says 24V on the adapter... isn't that too much for Molex? If I recall well they are 12V connections.

Yeah,that is way to much for the molex.I have a feeling if you try to connect it to a molex, either you will burn out your psu or the controller will smoke.

That's an LED controller right? You're not going to be anywhere close to 24V * 3A output - that would be 72 watts. Since it says right on the controller it will accept 5-24V input, and it has a black and red wire, I would connect it directly to the 5V (that's red and black) wires in the 4-pin Molex connector. Molex connector has 1 red, 1 yellow, and 2 black wires. The blacks are common ground, the yellow is +12V and the red is +5V.

Ok I'll give it a try. Hope this doesn't fry my PC ! :S

Edit: Do I wire this directly to the Molex coming out of the PSU?

If you want to be sure it won't fry anything, you could always wire it up to a 5V DC power supply and an ammeter and check the current it draws. LOL.

I managed to wire it. The LEDs worked at first, but broke afterwards :\

EDIT: The LEDs are magically working in.. No idea why, but good! smile.gif
