Hi guys,

I've got a 5m rgb LED strip which is rated at 72W. The power supply is rated at 12V at 6 amps, so that's good. However, what would happen if I were to connect another meter of LED strip to said 5m strip + power supply? Would it work, would it burn down, would the leds shine less bright? The leds are parallel so removing (or adding) LEDs is possible.

Thanks!

Hi
Since your power supply is rated at 72W there is nothing spare so you would overload the power supply causing overheating and possibly a fuse to blow.
To add more LEDs you would need to replace the power supply with a higher rated one.

Okay, so what about adding another power supply to the other side? Would that work keeping series and parallel in mind (not the biggest expert at that part).

No you wouldn't want two power supplies connected together which is what having one at each end would do.
You could leave the strips unconnected and each with its own power supply and both power supplies being fed from a common point.

Your power supply is rated at 72 watts. To work this out you multiply 12 volts x 6 amps = 72 watts. If you were to add two power supply's to one strip and controller it would not work, because in 'lamens terms' they would be fighting against each other.
If you were to add more LED strips to one power supply -so that the total wattage of the LED strip is more than the wattage of the transformer,then the transformer would be overpowered and will not work. The LED strips will keep switching on and off as the transformer will turn on, realise it is overpowered and shut off( protection mode)).
The only way you can add the extra 1m strip to your 5m strip is to get a higher wattage transformer. You can purchase a good quality 100 watt transformer for around £30 See here.
