so if its a 12v power adaptor how can i go around and connect this with the PSU? im not into electronics so i dont know if this will work but is it possible if i cut the male plug from the power adaptor then connect it to a molex then to PSU? and will it not harm my PSU if i do this modifications? but i dont know how it goes for the wires that will be connected with the male plug for the adaptor.

PSU>>White adaptor>>LED instead of Power outlet>>Black power adaptor>>White adaptor>>Led

Im talking about the white adaptor, is there in any way i can use my PSU to make it work without using the black power adaptor that came with it. Warning: Spoiler! (Click to show)

I am not 100% sure, but from what it looks like in the picture you posted, that the white wire from the controller goes directly to the LED strip. If thats the case, then it should be a 12v system and you should be able to hook it up to your PSU. You would have to figure out which wires are +/-, but then you just hook it up to it by cutting the wires on the adapter you posted above.

That thin white cable is what you need to power with 12V from your PSU. You need to take the wire hightlighted in BLUE below and cut the plug off of it so you can solder on a 3 pin fan connector to plug into your PSU or switch or whatever you plan to use for a connection.
Please ignore the above comment as it's wrong!

Sir, that white chord is for the Reciever of the remote.

This chord goes at the top of that white box. what im trying to say is can i connect this to a molex if i cut it from the black power adaptor?

You have two boxes there. One is the controller which manages the lights. The other is a power brick. Check the specifications on the power brick to make sure, but it should be 110vAC in, 12vDC out. If it says 12vDC out, then you can chop off the power tail near the brick and wire on a molex connector or other 12v interface of your choosing. I recommend testing the output with a mulimeter to verify polarity. If you wire LEDs backwards, they won't light up. The cheap Chinese made controller may or may not have reverse current isolation of some sort, and reversing it's power might be unfortunate.

Thanks. i cut the black wire from the power brick and saw that there was a small wire a red and the other was a black. So, i think its the same -/+ for the Molex right? will try it soon then ill post the outcome. hope i get good results:thumb:

you are absolutely right, the controller on these things is of very low quality, i managed to brake one very easily

Im talking about the white adaptor, is there in any way i can use my PSU to make it work without using the black power adaptor that came with it.

you can connect that led strip to a 12V molex, with a bit of luck you can find an adapter already made (i have one left over friom a Scythe amplifier that works perfectly)
But be careful not to make any false contact, if u plan on doing any kind of soldering: the smallest touch between, say, red and blue channels will mess up your whole colour scheme; 12V channel touching something else is bad too smile.gif
Also just a heads up, from your picture that looks like a lower density LED strip, ther LEDs are more spaced one from the other so you end up with less LEDs, thus less light; i had one of these low density strips when i got my 2nd controller and the difference is huge; if you can try to get a denser model
post #228 of 598
PS forgot to mention that i did end up using the LED controller connected to an adapter outside of my PC case, instead of connecting it to the PSU, because the said controller is just too cr**py to connect to any decent equippement, i dont want to end up paying more for these LEDs than i should; also, i dont remember much electronics from school, but is it ok to connect a low amperage controller (the original power brick is 3A) to a single rail PSU (dont remember how much is mine, but much more than 3A for sure) ?
Anyway, the good thing about this somewhat messy solution is that now i can turn LEDs on even when the pc is off
post #229 of 598
actually that picture is for reference. the adaptor and other periphearls are almost identical with the one that i bought. i dont have my ipad to take a picture for the progress but will update once done hehe. biggrin.gif

^^^^^^^^^^^^^^DO NOT CUT THIS WIRE! It is you IR receiver for your remote!



Hope this makes sense:



This is what will plug into your controller:
