I wanted to know how much power (watts) in hour will the comp w/ 300W PSU & all the components listed below in my main rig will draw?

I also have a 56K modem (duh :))
SB Vibra 128 PCI
NIC
10Gig Quantum fireball HDD
floppy
x40 Toshiba CD-ROM

That is a good question. I don't think it is very much electricity but I'm not sure.

i heared some where if you leave a compuer on all year it runs about 30 bucks extra

Interesting, a lot less power than I thought...

Actually I've heard that leaving your CPU on all night 24/7 saves more money than turning it on and off. Reason is because your PSU gives off alot of power to jump start the HDD, CPU, RAM, MOBO itself etc.

every one says that but i think its a bunch of bs

its not a car where you need to move something physical to get it to roll over.

its like a light bulb ( very complex expensive lightbulb) if you filp it it may suck in a little bit extra power but very neglagiable

I agree... It would have to suck an ENOURMOUS amount of power in an instant to equal the ammount of power over a day. Just sounds fishey to me.

This is EXACTLY why I want a multimeter... Then I can find out how much power this pooter actually uses! (and just how big this 'spike' is the people talk of!).

Here is the short answer ! 300 watts divided by 120 volts = about 2 1/2 amps or roughly 2 floodlight bulbs. Thats if the power supply was at full draw. They are usually at about 1/3 their duty cycle most of the time. so the power consumption is about the same as a 100 watt light bulb . Boy that short answer got long fast !

True but factor in the power your monitor uses if not in standby mode or energy saver not being used in a 24 hour cycle and that light bulb may be using more energy than you thought. :)

True , I did not take the monitor into account . I would say it draws 1 amp also - 120 watt bulb.

You mean you people don't have to turn that crank thing down in the front of the computer to get it to turn over?????

thanks but I wonder if there is a site/program that would tell you how much power the computer is using. kinda like Motherboard but maybe Powerboard monitor!

On the back of the box that my antec came in it says:

Input Current 8.0a for 115vac, 5.0a for 230vac.

8*115=920w

Thats if it was running full load though, which im sure it never does. If you figured about 1/2 of that for normal load your looking at 460w, +monitor.

And my Sceptre monitor draws 1.3 amps. @120v that would be just over 150 watts.

Its certainly negligible compared to what your AC / heater (and maybe water heater) can cost you. But finding an exact number is a worthy cause. Maybe do an experiment where you turn everything off except your PC and check the power meter outside your residence.

I don't think that's quite right. First of all, you are attempting to calculate the current in an AC circuit using a calculation that, I believe, only works for DC. Second of all, there is no way in hell a computer will only draw 2 1/2 amps. Most PSUs are rated to draw 10-20 amps. I have several fans in my computer that will draw an entire amp themselves. Add a peltier and that's easily doubled.

Anyways, I would expect the computer to draw a MAXIMUM of about 15 amps, possibly much lower. I could guarantee that it won't draw over 300w for long.

I see you guys are going to make me modify an extension cord so that I can put my clamp-on ammeter around the hot leg and measure current. :D Any electrician around should have a clamp-on ammeter, if any of you have a Dad, friend, etc who happens to be an electician.:p
