  • PSU Calculations?

    It's been a while since I've done any maths releating to the PSU but I remember there was a calculation releating to the 12V rails and amps or something along those lines and it told you something very useful. I just can't find that calculation or remember what it tells you.

    Can anyone help?

    What are you trying to work out exactly?

      amp-age and wattage probably.


      For PSU its 12W in 1A on a 12V Rail.

        Ahh yeah something like that, I've been trying to figure it out all day and I think what I was trying to find was the maximum watts output on the 12V rails of any power supply, I found that if you times the amps by 12 then it gives you the right number. Thanks anyway guys!

          Power = Voltage x Current
          Or....
          Watts (W) = Volts (V) x Amps (A)

          Hope this helps buddy.

            You could try and use an online PSU calculator liek this: http://www.thermaltake.outervision.com/index.jsp

            I dont think they are 100% accurate but can give you a rough guide.

              With anything I'd factor in a 10% margin of error.

              Add 10% to the consumption suggested by a calculator and reduce 10% from your units rated output.

              Bear in mind that unit's ratings are for peak consumption for a few milliseconds (you know how marketing works) and also that over time every one of your systems components will be worn and producing a greater strain. With heat too you add an increased resistance load across all components and nothing bolsters this more than overclocking.

              It's better to replace a PSU before needed than most of your system components.
