You could conceivably get 7v, 8.3v, 24v, 17v, 15.3v, and 1.7v (may have missed a couple there) from that supply. However, DO NOT simply tie the leads together. In any of those combinations, you would not use the ground lead at all. For example:
- If you want 7v: the + lead would be 12v, and the - lead would go to 5v.
- If you want 8.3v: the + lead would be 12v, and the - lead would go to 3.3v.
- If you want 24v: the + lead would be 12v, and the - lead would go to -12v.
- If you want 17v: the + lead would be 12v, and the - lead would go to -5v.
- If you want 15.3v: the + lead would be 3.3v, and the - lead would go to -12v.
- If you want 1.7v: the + lead would be 5v, and the - lead would go to 3.3v.
and so on...
Also, the output current would be limited by the current capability of the lowest rail. So, if you used the 12v (34A) rail along with the -5v (2A) rail to get 17v, your total current would be limited by the -5v line, which is 2A.
