But I'll look and see if I can successfully test the voltages for it. It might prove a bit easier from the card rather than the ATX connector. Especially as that would involve putting my hand in further whilst it's powered on.
Avoid bridging means to not accidentally touch two neighboring pins with the same probe, creating a short circuit. Practice with the power off if you can comfortably put both probes on the test points, supporting your hand with your fingers on the board to keep it steady.
This is what you want to do: https://youtu.be/fgLUr7GE7Ns?t=470
Only horizontally mirrored, since the regulator on your card is upside down. So in your case, keep the black probe on the right pin and touch the left and middle pin with the red probe.
