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.
There are two types of 8-pin connectors...

The first type of 8-pin is 4+4, used for CPU power, plugged into the motherboard. The second type is 6+2, used for mainly the GPUs, but can be used for other compatible devices. AFAIK, the won't even fit into each other, because the pin casings are different -> different arrangement of square ones and square with two adjacent corners cut down.

If you still need help, please, send some pictures.
