decided _not_ to upgrade power supply

found new use for oscilloscope - in monitoring power supply.

you can plug your oscilloscope to the + and - of your power supply.

that way, when you run your experiments, if there is a surge in voltage or what have you, you will see it on the scope. of course for a dc power supply, the oscilloscope has a boring flat line for most of the time, but its purpose is really just for those moments when the machine might pull more juice or less and this is a great visual way to monitor and detect that that has happened.
