I went and bought the PSU today, but unlike the YouTube videos, I only see two 4pin connectors joined together that slide apart. Are these the correct cables to power the board? I'd rather know for sure before I go cutting up a new PSU.

Looks good.
The cable colors are standardized internationally for PC PSUs.
Yellow is 12V, Black is GND.

Any idea whats wrong with the motors? this happens and they are all making ticking noises while they're not moving.

Sorry the video doesn´t show anything worth mentioning.
You could tell us, what you expected to happen, than we can compare it with the outcome.

Clicking sound is probably coming from the extruder, skipping steps?

All of the motors start to clunk and the movements arnt smooth and continuous. They're fine once I click motors off, but about if few seconds after being connected to the printer, all the motors start to click.

Rather than cutting up the power supply, why not buy an adapter to connect to the existing wires? That way you can swap out the PS if it should ever go bad.

Really not sure what your point is. confused smiley

not that difficult to swap out the PSU if it did die.
