Hi, Maybe you can help me. I have 2 ports close to each other on my motherboard for a 8 pin EPS12V. My power supply only has one such cable. I do have a left over 4 pin ATX12V connecter that’s not being used. Should I fill half of the other 8 pin slot with it??? And if so, does it matter what part of it as long as the polarity is the same?? Or shouldn’t I bother??? Will it make any difference??? Thanks in advance.
Many times the 8 pin is not necessary. It is used for particularly high powered cpu's and overclocking. The 4 pin connector should fit in OK. Try it.
Otherwise you should be able to get a 8 pin adapter.
