Please see the picture attached - what does the orange, red, yellow, etc mean?

Im looking to get a new PSU for the new GTX 770.

The Corsair CX600M I want to get DC output are -
+3.3V@25A, +5V@25A, +12V@46A, -12V@0.8A, +5VSB@3A

My current DC output are
+3.3V@50A, +5V@50A, +12V@24A, -12V@1A, +5VSB@2A

The orange and red states that it is 50A on my current PSU while the new PSU I want is 25A each ? WIll I have less power, is that a disadvantage?

The 50A and 25A ratings are for the 3.3V and 5V outputs which aren't used much in a PC. The important one is the 12V which powers drive, GPUs, and CPU.

With the Corsair you'll be fine since it has almost double the 12V amp rating.
