Generally i use psensor for this stuff, but idk if this will integrate with that. If you just run the sensors command and it shows up there, then it should show up in psensor too.

Not from PSU data, but I was running Kepler on my dev servers. But then I stopped because it correlated strongly with system load and didn't really think I learned anything new from graphing it. Having the full system usage might actually make this monitoring useful.
