overclocking and electricity cost

[christianw]

just curious, on i5's and i7's about how much more current draw are we talking?

i was just curious cause ive never read anything about the topic. does overclocking add a signifigant amount of current draw enough to notice an increase on ones electric bill?

Yes.

The highlight of the article for me was the efficiency comparison at the end.

I highly recommend running a baseclock of around 160 with turbo as a result of reading this comparison. It's the only overclock that I can run 24/7 without losing sleep, because it's actually more efficient than stock.

yes and no, depends what you pay now and if you would notice $10-$20 more a month asuming your comp is always on

Even if it is 100 watts more (unlikely), you aren't talking about any real money when it comes to your monthly electric bill. Depending on where you live electricity is something on the order of $0.10 per kwh, so you are looking at a penny an hour more for that 100 watt increase in power (assuming it is using the full 100W constantly).
