Computer Power Supply to Lab Power Supply - Part 3

i love this man!!!

and noone asks the question, why is there an " igniter" button on there :-o

[nlhans1990]

I wouldn't recomended anyone using a ATX power supply for a lab power supply. First because it isn't (you can't choose a voltage down to 0V), second because if you short the supply it will probably go bang or powers off.

@nlhans1990 you forgot to say that there is a ton of noise and junk that would come off-it is switch mode, after all!

[beteigeuze1314]

@nlhans1990 well you can get from 0 to +24 volts if you get a voltage regulator and connect it to -12v and +12v but you can't get much current out of it.

[starlite2991]

yes but that is with no load. That is why the voltages are higher on some of the outputs.

[BRADHblackdragon]

hi, can you get more than 12v from a pc power supply..e.g. can you sum 12v rails?thanks

[sorstudios]

Are you using a TRUE RMS multimeter?

[Penfold8]

Would it be possible to add a potentiometer to each of these outputs to get them directly to the said voltage. I know it's find to have about 5-10% variance as demonstrated here.

@Penfold8

that does not matter as the voltage is DC, with very little ripple..

you only need TRUE RMS for AC, PWM and likewise..

that is cool i wish i was taught that stuff

[chucksheen]

Awesome!!!
