    Desk Build - Electrical Question


    As per the title I am currently doing a desk build for my PC, and this is my first desk build. As part of this I am using some illuminated switches remote from the motherboard, and also a UPS.

    I have two questions

    1) For the 2 pin cable that connects to the PWR SW pins on the motherboard, what gauge wires should be used? is there a maximum length of cable used?

    2) I have a little UPS (1000w) which has an LED on the front of it to show the status. And the switch LED requires a 12v feed, what options do I have here? I don't know much about the electronics side, maybe a relay controlled by the UPS LED switching 12v feed from a molex connecter off a PC PSU.

    Many thanks

    Sno what i understood is that he want to use the power from the ups to power up his desktop build.

    If that's the case i think that it is impossible to do as the led uses small amount of amperes .

    to explain a little further I have added a picture of my UPS and the illuminated switch. So basically I am using the illuminated switch as a remote status LED for the UPS.
