PSU Calculations

[sycogrim]

Hey Folks

So I was linked to this site via via via someone , and this site calculates the average scores on how much power an average person consumes of power when running their PC.

My Current score is 442Watts of power generated when I start up my machine. This should give people a rough idea of what PSU you should be buying with all the components you have attached to that beast sitting on your desk/floor.

tbh i use to think that this site was the shit until i relised that psu wattage isnt everything, these days i would rather go for a psu with a good 80 PLUS ratings ... antec has some decent 80 PLUS platimum rated psu's that wont break the bank

Yes, but will you take a 300W 80+ PSU if this calculator tells you you need 442 Watts at least? This calculator does help.

well if its efficiency rating is like 90% or more then why not? i do think that this calculator overstimates abit ... like it says i need like 442W psu yet i'm running a 400W seasonic psu with no issues at all, rock solid performance

i do like the part that they state:

The recommended total Power Supply Wattage gives you a general idea on what to look for BUT it is NOT a crucial factor in power supply selection! Total Amperage Available on the +12V Rail(s) is the most important, followed by the +5V amperage and then the +3.3V amperage.

this text should be bold and bigger!

There was a PSU calc stickied but I guess they thought no one used it so the sticky got removed.
It is also the only psu calc that is worth using.

Download it and run it. It is 100% correct I have tested it on over 30 builds.

Thanks, I was actually searching for this the other day. Bookmarked!

I think the PSU calculators over-estimate a bit to compensate for aging, because PSU's do age, and also because it is better to have too much than too little, and cheap enough to move from "enough" to "a little extra."

I'm wondering if there is really a difference, or if it will make a difference in my life, between 80 plus bronze/gold/platinum/whatever.

+1 to Weaklings_Inc, I've run crazy PC's using 80Plus efficient PSU's which had quite low wattage outputs, for instance, my Shuttle XPC which was quite high specced at the time didn't have a very big PSU but it was very efficient.

Sadly, now that I'm running a mid-wattage PSU which is terrible and cheap I'm starting to experience issues even though the calculator puts me at 484w which is much less than the 600w PSU I'm using.

a reduction in electric bill, means more money for other things ... like a rise in the petrol price

Ah the joys of paying a fixed amount for electricity
