1x4 pin + 1x8 pin for 12400F + TUF B660M

[Gamer Guy]

I am looking to upgrade to 12400F and Asus Tuf Gaming B660M Plus non-wifi. GPU will be RTX 3050 for casual gaming. When I put these in pc part picker, the compatibility notes show that my existing Corsair CX550M does not have an extra 4-pin CPU power connector but the mobo has.

 

Even though 12400F doesn't need more than 1x 8-pin, from which 12th gen CPU, when paired up with this board, will I require that extra 4-Pin connector? Is that something I can buy one extra from Corsair and plug it in when I upgrade in future to like 12700/13700 tier CPUs running at stock?

No, you don't need the extra 4 pin.

Nope.

The 8 pin header, at minimum, can supply 384w. The closest anything on LGA 1700 currently gets to that is the 12900k which draws about 230w under full load, well under the 384w the 8 pin can supply. I'd highly doubt a future 13900k will draw more than ~250w under full load because that would be nearly impossible to cool, so that extra 4 pin header is just on the board for aesthetic reasons, it serves no functional purpose.

Why would they choose to show aesthetics instead of giving a fan header at that place which will help connecting rear/top exhaust fans easily. It already has good number of fan headers, but still . Anyway thanks for explanation!

Because most people think "Oh, it has more power connectors, therefore it performs better," even though that only matters when it's being overclocked on sub-zero applications, which you aren't gonna do on a B660 board.
