Old PSU and AM5 B650

[rangor gubbins]

I have an old (but so far reliable) PSU:

LEGION HX 750W | SUPER FLOWER

Please contact the distributor in your country for the availability and quotation

www.super-flower.com.tw

which has
1 x 20+4 pin
1 x 4+4 pin
1 6+2 pin (for sli)

I have just ordered a B650 AM5 board and noticed it has sockets for:
1 x 24-pin ATX main power connector
1 x 8-pin ATX 12V power connector
1 x 4-pin ATX 12V power connector

The system also has an RTX 3060 in using up an 8-pin supply.

So, the PSU seems to be missing the 4-pin connector? Can i use the 6+2 pin for the 3060, then use half the 4+4-pin for the motherboard? Or is it new PSU time?

The AM5 motherboard you only need to use the 8 pin (4+4 ) for the CPU the extra 4 pins is for overclocking.


Which motherboard is it ?

Should be fine with just the 8 pin CPU power.

You can get 8 pin 6+2 pcie to 8 pin 4+4 eps but would only do this as a last resort.
