PC Power consumption calculator??

[.Lethal]

Hi,

Just wondering where I could find a website that has a calculator of each piece of hardware and the max wattage it eats up. I know there is a few about but I dont have any links saved (and its been a good year or two since I did this).

Anyone remember or have any links handy? just tried a quick google search but got nothing solid.

EDIT: just found "eXtreme Power Supply Calculator" and am wondering if this is any good?

Most people seem to recommend this one:

Although ASUS also have one, here:

Thanks paradigm

Yep the eXtreme one has been around for quite a while now and is fairly respected

Just a thought after having a run through them both.

The ASUS one is garbage, even before talking about drives, RAM, fans, and god knows what else, the ASUS one already said I needed 800W+.

Which is balls because I'm running fine on a 550W

Oddly enough, the first link I posted said I'd need 567W, assuming my video cards were 2900XT's. As the 3870's use less power, I'd say its a pretty good estimate.

Yea I thought the ASUS one was crap. The other was more acurate from what I was going on.

I'd never seen that one before, it gives a pleasingly low number which I'd think is roughly correct based on my system but has relatively few options and isn't the most intuitive designed in the World.

I've used the one at Extreme Outervision quite a few times and it seems good if a little overzealous in judging the required PSU on occasion, better to have too much capacity than too little though I think.

PSU recommendation went from 500w to 700w when I changed the VGA card from 6800 to 8880!

Just worked out how power hungry my overclocked pc is!!

All stock that PSU calculator recommends a decent brand 350watt PSU. Recalculate it with my overclocked/overvolted CPU, RAM and GFX and it then recommends a 581w PSU! lol

Currently running a Tagan TG580-U15 580W psu

Presently looking into getting a UPS, really didn’t know I needed such a beasty one for my current setup, 1000VA min

thanks for the links
