wow. that is really useful! this should be made a sticky. I know i've seen my share of "how much power does this take?" threads. Thank you

It wasn't updated for 2 years. And, yeah, there are 7W AGP cards

Too bad it doesn't have the Epia chipset. Also, anyone know how much to add if you're running a lilliput (or two) off the power supply?

lilliputs take up 9 watts or at least mine does

Some of those values are not right.

my western digital 80 gig 7200 rpm drive takes .45 amps from the 12 volt not 2.2 amps like the calc suggests. I would recommend looking at your hard drive and cd roms ... the values are printed right on the top for you.

Also I have an AMD duron 750. It pulls most of its power from the 5 volt rail not the 12 volt again like the calculator says.

Most of the new processors pull their power off of the 12V rail, so they are right in that respect. However the 7W AGP card... even though they do exist, they do so in garbage, newer AGP's take anywhere from 15 to 70 Watt.

If your motherboard has an additional 4 pin square shaped power connector (This is separate from the regular 20 pin motherboard power connector). Your motherboard will give the cpu its power from the 12 volt rail. If you do not have the additional 4 pin connector on your motherboard then your cpu will get its power from the 5 volt rail.
