can one use cpu 8 pin cable on smps to power graphic card 8 pin connector?
similarly can we use 8 pin gpu connector on cpu 8 pin?

thanks
 
because the PIN out is different. Also the keying of the connector is different

a CPU connector has 4 black wires and 4 yellow wires. the yellow wires are on the side of the clip.
a PCIe connector has 5 black wires and 3 yellow wires. the black wires are on the side of the clip
