Just in case any of it helps;
Some PSU's require a load on some of the voltage lines to make the DC output smooth and within tolerance.

here is my supply, it supplies 12volts at 12 amps, and only requires removing of wires, and connecting the green wire to ground. i did this myself, without any online help.

Be warned guys.... Those sort of modded PC Power Supplies are banned from use here in Aus. They rarely meet the appropriate electrical standards and are prone to going bang....
I know its tempting because they're so cheap, but they're rather dangerous. Anyone here turns up with one they get sent home.

I think the main problem with attempting these conversions is people over-estimating their abilities - I have said it many times - You should not attempt to modify a PC power supply unless you have the appropriate skills and knowledge.
But overall it is similar to many other types of possibly dangerous machinery or equipment - if you fail to heed the warnings about the dangers then you only have yourself to blame when everything goes wrong.

Yes its true that some of these power supplies rarely meet the electrical standards but not all of them.......mostly those cheap power supplies that are made in China are the dangerous ones......
And those numbers on the power supply such as the Wattage rating should not be taken seriously......as long as you dont overload them to the near limit, then the power supply would be just fine.....
