Like i said before in my previous posts a Computers PSU is capable of handing "unlimited" amperage (to a point and i was told this by an electrician) it just gets hot so you can pretty much run anything you want, and all it will do is get hot but you don't want to overload it so that its about to catch on fire, try to find a decent PSU maby 15Amps+ on the 12V rail and that should be able to handle anything you plug into it.

Ya I don't know a lot about PSU's but I know electricity, there is no such thing as unlimited anything. Everything has a limit. Even if you thermal out, that's a limit.

Look near the end of the thread that was linked in the first reply you got.
A few pages from the end I posted some pics and diagrams of pinouts etc.
If you need any more info, just ask or PM me.

my guess is you can use up to the PEAK output, but they are in danger of thermaling. the continuous output is maximum output at operating temperature. you can boost this with a larger fan (sometimes!)

What rail is that rule referring to because i have a 550w PSU and it is rated at 19Amps on the 12v+ rail and the other rails (3.3, 5v) are way above this i think the 3.3v is 35Amps and the 5v is 45Amps, so i don't think that rule works unless i have got it wrong.
You could use a lamp instead of a resistor, i prefer a lamp because it doesn't get hot and it is very easy to swap if it blows also you know when its on
, it is a personal choice though some people prefer lamps others prefer resistors either one does the same thing

does anyone know what the cluster of brown wires is? my PSU has wires that aren't in either of the instructions. i shocked myself though (and burnt myself on the soldering iron, and cut myself when drilling the holes in the case, and banged my head when i put the power supply on the floor and stood up under a table. i don't think this is worth the effort...)

i found that, and it kinda works, but theres a whole bundle of thicker and darker coloured brown ones. stumped 
i might just ignore them and stick a more powerful lamp or resistor in, and maybe it will work, but i couldnt get a 540 to spin off the 12v output (gnd and 12v attatched to the motor) i had enough juice out of the 3.3v to spin it though.

I have made one of these and it works great, however it only goes up to 16A is there a way to link two of these together in paralell or sometihng so that they would be a combined 32A
