Furthermore, 3*75W < 240W, so they are still banking on you not using all 30W channels simultaneously at full load.
At any rate, I read the product description at the link that says a single Molex connector (or at least that's how it was implied when I read it). If I am mistaken on my interpretation, then you have my apologies.
Molex, nor ATX Specifications outline a limit for a molex connector.
PCI-PEG does outline a limit for adapters and connectors.
I do not contradict myself either; as it's what's outlined by the manual though that does not indicated any current limit.
And yes, you can use the full 240w on the controller across all 8 channels is there is no current limit.
You could argue that pins on a molex connector are generally rated for 8Amps before they heat up.
So 8 x 3 (because you're only using the 12v & ground wires, and ground doesn't carry current) is 24; so 24A theoretical limit. Then 24x12 = 288w Potential.
I would like you to define & show proof to molex connectors having a current limit.
There has even been testing on this though; and they found that up to 32.5A on a 12v wire was safe before damage occurred. (Source
You are confusing PCI-PEG Limits with non existent limits for Molex connectors.
The reason a Molex to PCIe connector uses two Molex connections, is to support the required 3 12v Sources of PCIe cables.
