@Finksy – Sent you a PM, please take a look at it when you get a chance.

I’ve posted my question publicly, since I have a feeling it might be a common one.  For the graphics cards that require an 8-pin PCIe connector (most of the non-reference cards or for example the popular Sapphire Nitro+ RX 480), what is the safest and cost effective methodology to attach these to your PSU breakout boards?  Is it safe to only populate 6 of the 8 pins on the graphics card itself or is that a potential fire hazard?  I know they sell an adapter, some cards even come with it, that combines 2 x 6-pin PCIe female connectors to a single 8-pin male connector, but that solution seems overkill to me.

Edit: I may have answered my own question.  In the kits, can you post a picture or describe the 6+2pin PCIe splitters?  Does this take a single 6-pin PCIe female connector in and split to two 6+2 pin PCIe male connectors?  If that’s the case, is it safe to power two RX-480 graphics cards from a single 6-pin PCIe connector.  Not sure what the power consumption is through the 8-pin PCIe port because I know that some of the power comes from the riser itself.
