Power draw of 5 computers.....

[Compman55]

Thought this may be of interest to you folks. I stripped a power cord to expose the wires, this way I could use a clamp on amp meter.

Found it quite interesting how much of a power hog the old P4 prescott system was. But also found it quite alarming how a new system can change power states so fast. It can idle low, and really start to hog power as needed.

It wasn't nicknamed Preshot (or space-heater) for nothing, and that's one of the slower ones you got there...

I suppose that's what you get when you pair a high-leakage process node with a 31-stage pipeline and very high (for the time) clocks. The really interesting part is that the 90nm process was capable of some pretty impressive stuff in mobile ("Dothan" Pentium M). Always wondered why Intel never made a desktop version of it. (think Conroe, two years early...)

Both PSU quality and power consumption has really come a long way in the last 10 years.

300 X 5 = 1500 X hours of use. Get a Kill-o-watt meter.

You do realize both the COMPUTER and the Monitors are using power?

An old Tube monitor (CRT) will use an awful lot of power.

I have two of my computers hooked up to 40" HDTV's.

How could you not know this???????

Two things I don't understand from this Post: First, where the 300 comes from, and second, that why you are suggesting him to get a Kill-o-watt if he already has an amperometer, which he actually used to get the values he posted.

It is probably a wolfdale E7500.

Well you could also look at assasins blog and look at some of his pictures and get an idea of how much power a HTPC is using. I think he used some kind of Kill-a-watt meter that you plug in between the power cord and the plug.

Yes I was just guessing.

So how much power for a full reboot from a cold start? I was told once the computer tests all the drives all at the same time during the bootstrap. So how much power do speakers use? 10 watts? What if you are charging your cell phone and running a backup on an external drive? Every time my computer boots up I can hear that darn DVD spinning up like a rocket.

AOpen (anybody remember them?) did actually market a Core Duo (Yonah) desktop board. The high end one had a 2.8 GHz CPU, which was pretty hot stuff (figuratively, not literally).

I remember AOpen. I don't recall if I ever owned any of their motherboards. I did, however, own a QDI (remember them) 845PE board, that happily accepted a *mobile* P4 S478/S479 CPU. Most boards of that era didn't allow that CPU, but that one did. I got the CPU for free from someone I knew.

Yup, I remember them very well. I used an AOpen i915GMM-HFS + PM 750 (1.86GHz) in my HTPC (I don't even think the term had been invented then) from 2005 right through to 2011. Only thing upgraded was a HD5450 for HDMI/Bluray compatibility. That's how good Pentium M was on the desktop...

I don;t mind the thread derail.....I do it too.

I remember aopen all too well. I had an AX4B, and my friend had this awsome AX4B-TUBE which was quite a creative venture. They shipped the tube in a box, seperate, and you plugged it in when you built the computer. It was not a good audio codec but if you were using a 2 or 4 speaker setup, the tube added a certain warmth to the sound. And it looked pretty.......

Kill-o-watt LOL

kilowatt is the word you are looking for

Obviously, you are not familiar with the kill-a-watt device.
