LED strip controller

[CyberWarrior]

Hello,

 

on ebay I bought some random 5V LED strip but I forgot to take controller for it. Will it work if I buy this controller?

those are usually 12V because LED strips are usually 12V.
But if you don't plug a 12v but a 5 adapter in to it, it will work if that's enough for the controller to turn on, and I don't know if it will.

This is the LED strip that I have. But what about this controller? If that doesn`t work I will probably need to buy a new one with controller. What do you think of this one? Will it be okay for PC? Any other recommendation?

 

One more question:

when I turn off computer LED strip is still ON. Why is that?

looks like you dont need an controller it should have buttons and is usb powered some motherboards have one or more usb ports that it keeps giving power to charge mobile phones while the pc is turned off or light the room in your case

That unit has a built in inline controller so you won't require one however I would make sure you are not overloading your USB port if you have a very long LED strip since most can only provide a max of 1Amp.

How to know is USB port overloaded? Yes I have inline controller but I want remote controller. I will first buy that LED controller than I will see will it work.

You must get a 5V based LED type controller the 12V ones linked will not work. As for the load a single SMD 5050 LED chip used 0.24W so for a 5V supply at 1 amp that can provide a max of 5W you don't want more than 20 LED chips for the entire length of the strip.

You mean linked controller from ebay or gearbest? I already ordered that from gearbest. In item description for voltage says 5v-24v...
