You're wasting a fair bit. You can get a qualitative sense by feeling how warm the fan exhaust is: I use my cheese grater Mac Pro to stop my uninsulated home office freezing up in the winter.

However, despite the savings, you may not break even if your PSU fails early due to thermal cycling (probably a rare event, but a PSU for a machine like the one you describe was probably built to be left on in a commercial use case.)

That reminds me of how the main computer lab where I went to grad school was normally quite chilly in the winter, except near finals. The heat generated by all the PCs, printers, and people caused it to be nice and toasty near finals.

Those cheese grater macs are real energy slurpers.
