> you simply suffer from retrocomputing

I love the way you phrase that! (I do suffer from that condition, too, in a way, if "suffer" is the word I want - but in my case it is select pieces of obsolete equipment sitting on my bookshelf. My favorite is an ancient IBM ISDN adapter (it still says 1TR6 instead of EDSS1 somewhere on the case) that once hooked up a mainframe to the outside world... ;-)

A friend of mine had an old Alpha years ago; was running NT4 on it. You'd watch the lights dim slightly when it turned on. I don't know the model, but the thing was huge.

My ES40 (4 x 667MHz 21264s) consumes 16A @ 110V. Most 110V US circuits are 10A.

I blew at least three fuses between that and the RX5670 (4 x Itanium), which consumed a similar amount of power @ 110V.

On the upside, depending on where you live, you probably save a lot of money on heating... ;-)

Is there a EnergyGuide heating furnace efficiency score for the ES40?

Resistance heating is pretty poor compared to heat pumps.

That's the joke that I was trying to make.

I think I remember reading or overhearing that Intel's chips somewhere in the Pentium 4 era were more efficient at converting electricity to heat than a typical hotplate. (Ratio-wise, at least.)

Household circuits are generally 15A or 20A AFAIK. Never seen one as low as 10.

Hmmm. Maybe it was 15A. A 16A ES40 plus other stuff plugged in to the same circuit would have happily blown 15A under load, I guess.
