How to power LED Strip Lights that have been cut into sections?

Hi Guys

I bought a 5m reel of white 3528 leds a while back and now have a use for them.  I'm going to run a strip under my desk and then another circuit around a shelving unit.  The lights came with a 12v 'wall wart' to power the whole strip.  However, I'm going to be cutting the whole 5m strip into three separate circuits.  Can I still use this 12v adapter on one of the sections?  or should I be looking for a lower powered 'wall wart'?

Would appreciate some help on this.  Not my usual area of expertise.

Was the strip designed to be cut? Many long strips do have sections that can be cut and a power adapter can be soldered in. In these cases they will run off a 12V DC source just like they did as a long strip. Since each section is wired to run off 12V and then all the individual sections are wired together in parallel. It all depends on the strip you have.
