[SOLVED] Asus Prime z590 8pins + 4pins and Corsair rmx 850w

Hi!

I have a doubt with a pc that I am assembling and has an asus z590 motherboard. The power connection to the motherboard has an 8-pin connector and a 4-pin connector. My power supply is Corsair 850rmx (brings two cables with 8 pins instead of bringing one 8-pin and one 4-pin.

1 x 24-pin Main Power connector - Ok -
1 x 8-pin +12V Power connector - Ok -
1 x 4-pin +12V Power connector - ¿? -


On the power suplly I have two 8 pin connectors for the cpu. If I connect both, one would have 4 pins left over. Is this ok? (4 pins would be sticking out without connecting).

do I have to connect both or is the 8-pin only enough? Do I have to buy a cable?


Thanks!

Yes, it is okay to have 4-pins left over. That is why they split apart.

You might be able to get away with only the 8-pin, but you bought a high end board, if you utilize all the features and overclock, you may need the additional power.

If you want it to look neater, you certainly can buy replacement cables.

One end of the 8pin cable is split, the other isn't. The end that isn't goes directly into the psu.
It is intentional for the left over 4pin to be left 'hanging'. No harm done.
