Topic: dual processor Pentium II 266 MMX : electrical consumption ?

[Quadrax]

Hello,

I have a DELL PowerEdge 2200 server with two Intel Pentium II 266MMX processors, two HDD Maxtor 120Gb and a power supply of 230 Watts.

I want to know how much power is consumed by one PII266MMX processor when it's working at 100% ?

If not, if somebody has an equivalent hardware architecture, I would like to know if this power supply is sufficient to work 24h/24h 7d/7d, etc... i.e. "non-stop" ?

Thank you very much in advance.

It is sufficent. How about searching on Intels website about the consumption or at sandpile.org? I think one sucks not more than 40 Watts under full load.

How about thinking before posting? It's a Dell server. They are built to run flat out 24/7/365.

Yes, it was also my idea but, I worked for a company which make thermal printers and, to decrease cost of a product which have not all options, it was easy to provide a power supply weaker than that of a full option model.

So, I ask that because when I bought my DELL server, it was provide with only one processor and HDD. Also, the power supply looks so little and I need to add two HDD which are very greedy in elctricity...

If I ask something, it's because, I thought before posting.

Just for information, my DELL server is issued from a lot of 90 others server exactly identical which issued from the same company which used this computers just for workstations without big fan power supplied.... That is a very strange idea, I know but, it's the truth.

So, it's natural to have suspicion about the power supply. No ???

Not too greedy. Only 3-5 Watt each

Not too greedy. Only 3-5 Watt each

5V x 670mA =  3.35W  yes, only for 5V power supply
12V x 960mA = 11.52W  (it's needed by rotation motor)

3.35 + 11.52 = 14.87W for one 120Gb Maxtor
so I use two HDD then P = 29.74W almost 30W.

How about thinking before posting?

  (no hard feelings)

Just a question for 1111 : When you say 3-5W, this is for what type of hardware ? so is it for the average consumption ? and in what case (full load or not)?

If I upgrade soon for RAID 5 it's up to 60W.
Later, it's possible that I need more space and use a promise IDE RAID controler which provides RAID possibilities for 8 HDD. Then, it's up to 120W...

When I build a server, I build a real server, not 80386 with only one HDD of 180Mb... LOL

------------------------------------------------------

I also ignore how much power is needed for the mother board because, there are a lot of chips on it to allow the use of dual processors, SCSI controler, PCI interface, etc... etc... It's an old technology mother board and, I'm sure, it's not better than the last generation of hardware which works with very high speed I/O transfers. (do you know how FPGA, CPLD, etc... or "simple" ASIC are designed ? because, switching speed and consumption are closely linked to the manufacturing technology (it's just like for processors)

Also, for information, electronic devices are designed to function in an ambient temperature about 25°C. Where I am, it's not air conditioned and, last summer, it was 40°C... so, I need a power security margin because, silicon electronic devices are more greedy when temperatures are up. That is the problem with them.

I "heard" power consumption for a PII can go up to 200W or 250W. I know, this is a peak consumption. For mean consumption, 40W in full load, it seems to me a little bit small, no ? Thank you mbachmann.


P.S.
I need information for full load to have confidence in my hardware.

(With only 15W of electrical energy, I can assemble electronic components easily with my soldering iron)
