If it's a windows system, just write an infinite loop one-line script in python or something.

I don't have any good way to max out the GPU though.

I normally measure (I also use kill-a-watt) something like 60 or 70 W idle, which accounts for 90% of the time, and usually what matters the most if calculating energy costs.  65W * 24h = 1.56 KWh per day, and at $0.17 per KWh and 30.4 days per month, $8 or so per month.

Idle power is what counts the most toward energy costs.  Max power is what you size your UPS on.
