Power Supply's?

by BKennelly / April 21, 2009 10:33 AM PDT

I have been searching all over the internet to find a way to figure out how to calculate how many watts I would need for a Power Supply to power a new PC.

If anyone could direct me to a site that is recent which covers intel's new processor's (core i7), and the newer graphics cards etc.

If you need me to clarify this any further don't hesitate to ask!

Any help would be greatly appreciated. Thank You in advance.

Brandon

It does not list all of the latest processors and graphics cards, but many are listed. Just choose the one closest to yours...you should always leave sufficient 'buffer room' since PSUs are not perfect and deteriorate over time, so a slight different between tow CPUs or GPUs will not make a difference.

Wasn't exactly what I was looking for

but I guess that it will work. I guess the main problem with it is that the free version doesn't allow for more than one video card. Because I was sort of thinking about having two video cards side by side in SLI or Crossfire.

Does anyone know where to find how many watts it would require to run two video cards in SLI or Crossfire.

Once again thank you in advance for your help

like a chart or something that gives rough estimates of what each part consumes wattage wise, but maybe listing more specific parts such as have a categories named like, Motherboards, Processors, Graphics Cards, Optical Drive, Hard Drive, Card Reader, etc. Then lets say under processors we would have the Intel Core i7 which consumes a 130 W and so and so forth after that.

Hope that helps explain better what I was looking for

And again thanks for the help

Rough estimates...
by John.Wilkinson / April 21, 2009 12:28 PM PDT

Rough estimates are given on the individual products...CPU, GPU, et cetera. There are simply too many combinations (billions) of components to create a chart representing them all. (Check the website of the respective manufacturers for those numbers.)

Tip: Using the estimator, see what the total wattage is without the graphics card, then with the graphics card most similar to the ones you intend to get. Take the difference and add it to the total wattage with the single graphics card.

Thank you for your help, I don't know why I didn't think of that earlier, eh eventually I would of thought of it but thanks a lot for your help
