I didn't read the instructions on that one closely enough the first time around - you have to use all the available power outlets (so there'll be a line coming out of each circle). Does that help at all?

There are multiple solutions, I've beated the game twice and, although I'm not sure if I got the same solution both times, I'm sure I didn't have puzzlebox's solution

Yes, there are multiple solutions. I had

both 10's and half of the 50 hooked up to the device requiring 45

If you count every solution with a different set of lines separately, then there are 856 solutions.

This includes many trivial variations though; for example, you can always swap each pair of connections coming from a single generator (and if they are connected to different machines, this gives a different solution), and similarly the four connections to the two 10 Watt generators can be freely permuted, et cetera.

If you only consider solutions different if some machines draw different amounts of power from different sources, then there are only 8 solutions:

Then you just have to join them up so that the sum of the numbers attached to each appliance matches the number shown on that appliance.

And here's what the solution looks like.
