So I need to be able to short my PSU for it to run without the motherboard hooked up for leak testing for water cooling.

I heard that you need to have a metal wire in the green lead and any black lead touched together on the 24-pin connector, is this correct? Can I just use the metal wires found at the end of molex cables? I assume you turn off the PSU before you do this and after touching the two leads and turning on the PSU it should power up.

Is there any load I need to have on the power supply to have it start up? Will a 24W pump be enough to start it up?

Are there any other precautions I should take?

I've already fried the black wire on a fan before but I'm not sure how it happened. I had the 7v fan mod with two fans in series and one of the black wires got fried but the other ran fine

Green to black like you said

The connection can be made either with the psu plugged in or not. You could put a toggle switch on it if you wanted.

With regards to the 7v mod, the main concers is how many amps you will be drawing. If you think about it, the 12v, 5v, and 3v lines are all designed to have current flowing in one directions based on polarity. When you use the 12v and 5v lines to get the 7v output, you are effectively changing the 5v from an anode to a cathode. Some circuits have tolerance to such conditions, some psus are one of them, but only below a certain power rating.

I might have fried that fan because I had red on red and black on yellow (opposite of what it is supposed to be)

I don't need anything connected besides the pump right?

Right.

Better to leave everything unhooked, in my opinion, while leak testing if you have the option

Like Bomber said.

I also prefer to just fire up the watercooling once installed without power to anything else. Pump should be enought to start the psu. Unplug everything else.

gl.

I still get butterflies the first time I turn on the power switch, saying to myself: I hope it starts.
