Fair enough but it seemed like a hell of a wallop for 5 or 12Volts, presumably it's the current that gives it the kick?
Concerning having a load to the PSU, I don't turn it on unless the charger is plugged in or some other item I'm powering.

the belt you felt might not be teh 12 or 5v it may be the incoming 112v on that side its hard to say.. Putting a load on the 5v side increases and steady's the voltage on the PS

Zrock,
As long as it is all normal then fine. Mind you the click/tick noise is a small concern but at the moment I'm putting that down to components energising.

I got belted with 230V, I'm in Italy!

guys, i just bought a new pcu / atx power supply to convert into a power supply for my lipo charger. my issue is it will only turn on for about 2 secounds before turning off. i have done the proper conversion of using 4 yellow wires / 4 black wires for 12 volts and done the green wire to black wire join i have also installed a 10 ohm - 10 watt sandbar resistor on a black wire to red wire [ 5 volts ] i have tried to get this working but it won,t let me. any tips ? its a 550 watt atx. HELP.

Most ATX PSUs have a small gauge brown wire that is a "sense" wire, it must be connected to the 3.3 volt (orange) rail. Look at the 24-pin connector that goes to the motherboard, you'll see that it is wired together with one of the orange wires. If you have removed that connector, you may have to solder the brown wire to the spot on the PCB where the orange wires are/were.

Also, some chargers have large capacitors in them that charge up when the charger is turned on, so you have to turn the charger on BEFORE you power up the PSU, or it will trigger the over-current sensors in the PSU and it will shut down.
