Sorry for another "water loop not filling" concern, hoping to receive some useful guidance on resolving this issue.
Loop sequence Res/pump > GPU > 280mm rad (top) > CPU > 360mm rad (side) > res/pump
Swiftech MCP655 PWM is connected directly to the reservoir (underneath).
I've attached a molex cable to the PSU using an ATX cable.
Tried tilting the case in various directions, but no improvement.
I'm very grateful for any assistance. I'm completely stuck. I've kept the reservoir cap on until a fix is found, but when testing it's off.

Where does the water get to before you see it stopping up? I would guess around the CPU block or near the 2nd radiator?
Although, I do see one potential problem - your GPU inlet/outlet are on the same port and they really should be alternate ports - in your case, looks like 'in' on the right, but should be coming out the top left. The way it is setup now would make your GPU block just a pass-through and wouldn't cool the card.

Rubix_1011 is right. The GPU inlet/outlet settings are incorrect and need fixing. Concerning coolant flow, does the pump seem to be pulling water or is there a lot of gurgling and air bubbles? If no water flows after a few seconds, turn off the pump to prevent damage from lack of movement. While priming the loop, I'll run the pumps briefly until water returns to the reservoir.
