Power Supply Calculator
I was interested in a calculator that figured out the wattage of a computer. Nice GUI and is being updated to the latest components as we speak. Take a look:

try this one:

and this:

this one is good for calculating overclocked cpu's power.

The idea of the "psu calculators" is that you can estimate how much power you might need. Were as the wattage meter is for when you allready have the system at home and running.
Small difference.
I guess when it comes to accuracy.
You can estimate, buy and measure and submit the results to the developer?
Still, even if the calcs are 80% acurate, that still better then guessing.
With regards to hard drives, you can read how much power they will "use" from the sticker located on them. Same thing with cdroms. Generaly 10W for 3.5" 7200rpm hard drive and optical a tad more, 18w for my pioneer 109.
Maybe SPCR should consider making one of their own? Just a suggestion.

that's not so bad. The Extremesystems calculator overshot my actual draw by 200W, while this Snoop one only overestimated by 60W. A pretty good estimate if you ask me.Sylph-DS wrote:That one is full of cowbell. It forgets to take into account that the AM2 versions of the AMD Ahtlon 64 3800+ take only 62W instead of the 89W the 939 version takes. Worse is, it still happens when you select specifically that you have an AM2 motherboard.
it's not too complete but more accurate... well, more realistic, lets say. the majority of them (except the two i posted) are simply trying to scare you into buying high-power psu's, complete with convenient referral links .
i recommend the "extreme" link for calculating cpu power-draw only, btw, in case i didn't make it clear. it has a nice separate calculator that you can use for that. handy for overclocking.

That's what I used it for prior to buying a kill-a-watt. The odd thing is that the calculator doesn't seem to work that well with Opterons. I couldn't choose "Opteron 170 1.35v" as my chip, I had to choose it based on the full part number, because if I didn't, it would overestimate the cpu draw by ~60W. I'm not even sure the full part numbers were there when I first calculated my systems draw.mcoleg wrote:it's not too complete but more accurate... well, more realistic, lets say. the majority of them (except the two i posted) are simply trying to scare you into buying high-power psu's, complete with convenient referral links .
