Please forgive my possibly too ignorant state.

I am trying to see if I can replace a power supply in any of my systems to include one that can power a GPU. None of my current systems have the extra lines form the supply. For example, a Tesla K80 needs to be supplied with at least a single 8-pin connector (if rated high enough) or two 8-pin connectors via an adapter cable.

In my research of power supplies for ATX systems, I'm finding different ones with several 4 pin connectors, but some of those don't appear to include the standard(?) 4-pin 12V for the motherboard. To complicate things, some of my motherboards use the 6(8)-pin connector themselves which leaves none for a GPU.

Can the power supplies with multiple 4-pin connectors be used by placing two 4-pin supply connectors into the 8-pin GPU connector?

Thanks for any help.
