Re: Wattage Calculation
As I understand it, and I could be wrong (as well as using incorrect terminology), but I beleive what you have calculated is the maximum possible draw in watts that could come from your system - but thats not the same as the normal operational draw.

If you hook a Pentium 100 to one of those big SLI-rated 1000 watt power supplies, it isnt going to draw 1000 watts. If you dont mind downing some servers, you could use a Kill-a-watt. Or maybe one of those clamp-on Ammeters if you want to not down them, but I wonder how accurate those really are.

Jupiter, Florida (561) 747-6107 From: Ralph Smith [mailto:[EMAIL PROTECTED] Sent: Wednesday, October 15, 2008 4:04 PM To: NT System Admin Issues Subject: Wattage Calculation Can anyone help me out and educate me on something? We are having some work done, and I was asked if I could supply the total wattage for all the equipment in our server room. I thought I could use the specs from the tag on each item, take the total number of amps, and multiply by 110 to get watts. What is throwing me off is that if I look one of our typical desktop PCs it is 6.3 A at 110 volts, so it would be 693 watts. The power supply is 300W max, so something seems to be wrong with my thinking. What would be the correct way to do this?

Redundant power supplies don't necessarily double your power consumption. Kurt Buff wrote: I second the kill-a-watt. Heck, get two of them. And you don't even have to shut down the servers, if you've got redundant power supplies, right? Or just use the one, and double the reading, or triple it for machines with three power supplies. -- Phil Brutsche [EMAIL PROTECTED] ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/ ~
Re: Wattage Calculation
No, they don't. But, they, if properly implemented by the manufacturer, will equally share the load of a running machine - nicht var? We're after actual consumption, after all...

RE: Wattage Calculation
These days, I wouldn't worry too much about volt-amps versus watts. Pretty much every modern server has active power factor correction. VA will be within 2-3% of watts.

Im checking out Wikipedia and elsewhere so I can try and understand this stuff I just want to be able to provide accurate information. Thanks for giving me a couple of places to look. ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/ ~
Re: Wattage Calculation
I'd still go for that Sears Clamp-on digital Ammeter. In the comments, people have said it is well more accurate than the 3% stated. Those are also EXTREMELY useful here in FL when the hurricanes come, and we have to wire generators into the panels for a week or two, and need to balance the load without blowing the generators breakers.
