Hello,
I have an ASUS TUF X570-Plus motherboard, an AMD Ryzen 7 3700x CPU, and a PowerSpec 750W 80 Gold PSU (from Microcenter).

My question is about the 12 volt connectors.

The motherboard specs say these are available:
1 x 24-pin EATX Power connector(s)​
1 x 8-pin ATX 12V Power connector(s)​
1 x 4-pin ATX 12V Power connector(s)​
Edit:​
This is from the manual: ATX power connectors (24-pin EATXPWR; 8-pin EATX12V_1; 4-pin EATX 12V_2)​
I see all of them available on the motherboard; however, the PSU has an EATX 24pin modular and an 8pin modular cable with 2x 4pin connectors.
Should I use the 24pin connector by itself? Or should I use some combination of 24, 8, and/or 4 pin connectors.

I searched and found that EATX is extended ATX, though, I cannot find exactly which configuration to use.

Thanks!

Some more information from the manual (page 1-15):

DO NOT connect the 4-pin power plug only, the motherboard may overheat under heavy usage.
Ensure to connect the 8-pin power plug, or both the 8-pin and 4-pin power plugs

Hi
I have the same problem. My PSU is a Sagitta from Nfortec, 650W 80 GOLD
No cable with 4 pins came with this PSU and I only have with 8 pins. Should be ok if I connect only the 8 pins without the one with 4 pins ? Thanks

Yes .
My PSU (Corsair RM650) also only came with 2 - 4+4 pin connectors for the CPU Power.

I can confirm, as I just straightened this out. If you are not overclocking, then you only need to connect to the 8 pin connector. Either a single 8 pin plug or two 4 pin plugs will work. Completely ignore the additional 4 pin connector if not overclocking. If overclocking then it seems you will need to use the additional 4 pin connector as the board/ CPU requires more power draw to be stable.

Did you use the 8 pin AND the 24pin power connectors?

Just an added note - when connecting up to the 8-pin, it's recommended to use two separate PCI-e cables (obviously using 4 pins on each) rather than a single 4+4-pin. The reason being that this will spread the load.
