I am changing the PSU of my PC soon as this was a pre-built, but as I am cutting zip ties and all that I notice that the leds in the front of my case are connected (soldered?) inside the actual molex. The molex itself just goes into the current PSU (Non-Modular). I can't see anyway to reconnect the wires to my new PSU (Apart from actually cutting and soldering them), so I was also going to ask if it is safe to cut them? I made sure the wires are ONLY for the leds, so it should be fine, but wanted to check first.
