A Molex most certainly does have a wattage limit! If it didn't, why would 6-pin and 8-pin connectors need to be invented for graphics cards? You also contradict yourself there by saying there is a 3-connector requirement, which wouldn't be necessary if there were no wattage limit on Molex connectors. 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.

I think he means the amperage limit for the wire it self.

the specs say "DC input: 3 x 12v (standard 4 pin molex)", meaning 3 standard 4-pin molex connectors are required.

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.

I've had some trouble with some FC5V1 LCDs showing up in a couple FC6s I got which shouldn't have been the case. Some other trouble I have noticed is that the FC6 only outputs 11V. I would of expected better quality MOSFETs to minimize the voltage difference to at least 0.5V. At least the hardware rep for Lamptron has been nice (Spawne32) but there wasn't much he could do as they are based out of China.

So if you have any problems, deal with the vendor. If it's a deficiency with the design you're SOL.

You're pretty much the ultimate resource on anything power-related in PCs. Imagine how much the world would gain in experience with your knowledge in a wikki.

Gimme your brain.

I was kind of hoping for a brushed aluminum finish now that I've just looked at it and gave it a second thought. I like the rainbow color though.

Oh don't worry; I have PLENTY of things I have written that will be published eventually.

It just depends when I can finalize it; I don't like to publish anything until I know I'm at least 90% done. (As you'll never really be 100% done except on dead tech.)
