I recommend this, its cheap and works well. Although a paperclip is certainly cheaper. Problem with plugging it into the board itself, is you'll be powering the board. You usually don't want to do that when you're filling the loop for the first time, as you don't want your components on.

Are you actually shorting the pins of the 24pin connector to turn that external PSU on?

Basically, in a nutshell, you need some way to turn the PSU on.
Flipping the switch on the rear doesn't power anything, it just allows the PSU to power something, if requested.

So, you can either connect it to the motherboard, and power buttons etc will do that. OR you can short the pins Karadjgne mentioned with either a paperclip or similar, or a specific PSU "tester" (which does the same thing). EVGA include PSU "testers' with most units, not sure about other vendors.
