I have this one.

It works just fine for spewing random power into things. I'm doing anything particularly sensitive that'll care about the things that you want a higher quality power supply for, and it sounds like you're not either.

So, probably fine?

Not that what you came up with wouldnt work, but a benchtop adjustable power supply is going to serve as a really good tool to have for testing components as well, this is just what i would get.
