What power would the 2m strip need?
In general all loads should be connected through transistors, mosfets or in extreme cases with SSR's.
It is a computer not a switchboard ;)

2m would need 2amp but what will happens if i use 6amp ?

If you use the 6amp the LED strip will just shine the same way...

so you're saying if i use 6amp with rg led strip it will not burn ?

Nops, 6amps is the maximum current your power supply can provide. It does not meet that it will give out 6A all the time. Your LED strip will only pull as much as it needs. Meaning they will shine just as bright, as Downunder35m mentioned.
In most (if not all) RGB strips (or any other LED strips), there is a current limiting resistor which will prevent excessive current flow which can damage the strip.
