I am wondering if it will be possible / beneficial to rig up the -5v line as the negative and the +12v as the positive to get a net 17v output from the psu. Should I just stick with the healthy 17A 12v line or attempt this theoretical 17v line
?
You will get 17 volts, but if you check the current rating of the -5v rail, it will likely be around 200 to 400 ma. - however, I suspect that it will not carry much of a load since the rail will overload very quickly. Stick with your 17A 12v line.
