Powering LED strips that are cut into pieces? Answered

I ordered an LED strip off Ebay and it came with a AC/DC adapter 12v 5A
It powers the 5 meter bright white LED strip great. However, if I cat this strip into say 3,4 or 5 pieces. I need to know what I need to buy to power each of these pieces.  My understanding is that the adapter that came with the strip will now be too powerful for the smaller strips and I don't want to buy over-powered adapters for the cut pieces.

Also how do I go about with the actual connection to the led strips as seen in my photos.

The adapter is never too powerful because it is a fixed voltage power supply.

Each segment group will draw as much current as it needs while the voltage remains constant.

As long as the cuttings do not exceed an equivalent 5 meters there is no problem.

You will need to buy black and red wire and assorted soldering tools to connect the strips in parallel.

You can cut them at the designated areas and just use them the same way the full strip was used.
They require 12V, the adapter gives 12V, so I fail to see the problem.
Sure, if you cut them all into tiny pieces and use them parallel your adapter might not like it, but if you want to use multiple strips you can simply connect the positive and negative terminals from one strip to the next with a pair of wire.
