Power consumption...am I doing this right?

post #1 of 4
Thread Starter 
Let's say my sig rig consumes 550w at full 100% load (which is roughly correct).

I have an 80% efficient PSU. So that would mean I would be pulling 700w from the wall (80% of 700w is roughly 550w).

My current charge rate is kwh(0.09564). That means, .7 kilowats(number of hours)(0.09564) + taxes = $x amount I pay.

So for the sake of ease of calculation, let's assume that I was running this rig 24/7 full load for, say, one week.

That means
.7(24)(7)(0.09564)=$11?
kilowatts(hours per day)(# of days)(charge rate) = $cost

So if my rig were to run full load for one week nonstop, it would only cost me $11 in electricity?

Am I doing it right?

That's about right, yeah. And around $40/mo.

looks about right to me.

Cool. I've never bothered calculating power consumption before, but it's a lot cheaper than I thought.
