Power Supply Calculator

Kougar · 06-03-2006, 04:35 AM

I've seen a few to date, but this one is simply impressive in the breadth and level of details covered. Besides overclocking, you can factor in Peak Utilization, Capacitor Aging (Explained at the end of the page), and Surge Compensation which deals with the power surge required when you first power on the system from a cold start. From my experience trying to calculate what my main rig draws, the number given was very accurate.

Yea, this PSU Calculator has already been posted a long time ago...but I wanna say that I personally think this is the BEST online PSU calculator.

I'm using this one ALL the time...and the good thing is that it's being updated ALL THE TIME with the latest hardware!!!

So...let's put it that way...VERY RECOMMENDED!!!

I think we should have an area in the site for keeping decent links like this just incase you forget them.

A handy "Links" section for overcloacking tools, small programs, and other tools like the PSU calculator.

Thanks Couger for the repost, I may be buying a new one soon. It never hurts to plug in the #'s.

I agree, we should have a topic area or FAQ that includes all these usefull links. This one was helpful, because I lost it.

I cant believe my Neo Power 480 will do Crossfire for me!
Everyone told me I would need as least 500 watts.
With my specs.,,it said 460 will do.

Total watts is one thing but the amount of amps is another especially for all the highend GPUs.

some psu's are like 800 watts and like 80 amps. will that ever be needed? arnt every1 trying to conserve energy?

For Quad-SLi yes. Also they will be needed once the G80 and R600 are out since they are suppose to suck up 200W.

i used to have 430watts for my 6800gt, 3500+ 3 fans, and hd. but i upgraded to 480watt with more amps, alot more stable. and psu has blue lights

Thanks, great calulator, I need something like this to help me with my new computer build. Helps to look at all the needs not just one aspect.

I was thinking of buying a 850W PSU but seems like I will only need 400W

I would double whatever they tell you. Not only for efficiency, but if you dont have a top of the line PSU then running it near capacity will end up blowing it up.
