I've noticed a fairly massive spike in my electricity bill from when I was using the reprap. Was used a few hours everyday - Lets say 1-5 hours a day. For maybe a month or two. Might not have been daily.

Bill went up by something like $200 for a quarterly period.
Unused, dropped down. Looks like it was the reprap which caused it?

My power supply is pretty similar to this:

I'm wanting to know if anyone has done any power consumption testing vs real world costs?

I'm in Australia and electricity are at a premium currently.

I was going to do some tests, then realised I have no idea how!

Thanks!
