The PSU won't "turn on" unless pins 20 and "X" are connected to each other. In my photo above, they are connected via the little toggle switch on the right (note the orange text) so one can turn it on and off like the I/O Board does (aka "Soft Power") using the switch.

If you purchased the switch (or have one), wire it to pins 20 and "X". If you don't have a switch, connect the two pins with a wire and the PSU will turn on as soon as you plug it in.

Having the on/off switch will make it easier to troubleshoot logic problems on the daughterboard, as that allows you to connect the voltmeter to various points and observe what happens the moment the PSU "turns on" (and then decides to turn itself off).

(In this case, "turn on" is not the same as connected to the mains/110V via the power strip)

(I don't think you need to order any more parts, my guess is that the broken solder joint on the potentiometer was the problem, and once you get the test setup going, the rest will be quick... could be wrong though.)

edit: The pictures in your last post don't all show the same wiring, which makes it hard to point out what you need to change (since it is different for each picture). In summary, for the PSU to turn on (so you get +5V and +12V), you need to have all of these connections at the card edge at the same time:

• Connect a load from +5 to ground
• Connect a load from +12 to ground
• Connect +5 Sense to +5V
• Connect the "On" signal Pin "X" to +5Standby Pin 20 (perhaps through the little switch)

If any of those are missing, the PSU won't turn on (except momentarily perhaps).

edit: Your wires are not too small for a quick test... when they are too small and you run it too long, they will get hot and perhaps the insulation will start to melt or smoke. If you are concerned, you can double them up or use bigger wire.

It is very unlikely the new parts are bad if purchased from a reputable supplier such as DigiKey, Mouser, Newark/Element14. Once you get the PSU turned on, if there is a problem with a capacitor, we can diagnose that issue.
