    Hi,

    I would like to get your advise regarding my future project for my old G20AJ,
    Currently running with stock power supply for GTX 745.

    1. Use 300 mm PCIE riser cable from thermal take. Will this be long enough?
    2. use external GPU/PSU mounted on rack. Will be using 650 w PSU solely for the gpu.
    3. wire the on/off jumper for external GPU directly from the G20AJ power button.


    Is there any thing i have to be aware of if I have to pursue this project?
    Do i need to make grounding cable for my gpu/psu rack & swap jumpers on my motherboard.
    Like how others changed the jumper when using 2 power supply for the G20?

    Thanks in advance!
