Amature using psu calculators

[dickmaurer]

I've been playing with psu calculators and they all seem to give a different numbers. I've gotten numbers from 300-650 watts! Could someone recommend a reliable calculator?

Also I've heard that it's best to buy a power supply about 100 watts over what you really need for efficiency reasons. Do I add this number to what the calculator spits out or does it factor in this number on its own? Thanks

I usually use PCPartPicker. It's still slightly over but it's one of the more accurate ones.

 

What are your specs?

What's the specs?
 

For (most) single GPU setups, 550w is enough.

Nothing out there is really that good that I've seen, what is your component list we can give you a more accurate value than what the calculators can do.

That system wouldn't draw more than 350W so a good quality 400-450W would be more than capable of powering all of that.

The specs of the part should tell you the demand, add them up multiply by 1.3 and round up to the nearest psu available.

The extreme PSU calculator by outervision is one of my favorites.

I usually do by hand but I use this one to give me an idea on the fly.

You gotta share dem specs and I'll spit out an estimate of how much power it will use and will give you a good PSU estimation for your budget!
