Im guessing you are using two of these processors, http://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+X5365+@+3.00GHzWhat should my expectation be of power usage on a $500 PC that will run BI well? I've had a hard time finding anything but max power consumption numbers on systems. My hesitation has been that I will spend $500 to save $10/mo - with a 4+ year break even it doesn't make a lot of sense to spend the money buying something new, for $500 I'd be much further ahead putting my money into other things (LEDs, appliances, etc) that will save more power assuming the job is done equally well by both machines. Not challenging opinions here, just looking to try to run the numbers objectively but haven't been able to get a result that makes financial sense yet. Would a good i5 machine with a couple of drives spinning consume 30w, 50w or 100w?
An i5-4590 will outpower those significantly (because of improvements to the processors that are not always evident in the passmark score but more importantly because of intel hardware acceleration)...
Here are some tests i did on a 300 dollar i5-4590

The difference can be hundreds of dollars per year. For example you state 240-280w consumption. Lets average 260.
At 20c a kwh (dont forget to calculate delivery, supply and taxes) that amounts to $454 per year.
A haswell i5 in the link above, even with a few drives added will draw about 50w or $87 per year. The system will pay for itself in a less than a year. You can also sell the old server for a few dollars...though I wouldnt have the heart to. I cringe when I see folks using old power hog servers...the money is going straight to the electric company.
