Question ASUS TUF X570-Plus EATX and ATX power connectors

[liamf9]

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!

You need to connect the 24 pin connector and the 8 pin CPU power connector.
The 4 Pin CPU power plug on your motherboard Only need to be connected if you are doing Extreme Overclocking (like LN2 OCing).

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, you can try. Should be fine if you don't overclock.

Can 2 4pin connections be used to substitute the 8 pin?

 

[Mcyd]

Also needing to find out if 2 4pin connectors are okay, as my power supply comes with 2 4 pin and no single 8 pin for the cpu

 

[DMAN999]

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?

 

[Mcyd]

Yes, you need both, only the 3rd 4pin port is optional and only needed if overclocking.

 

[WildeyeWillie]

Yes, you need both, only the 3rd 4pin port is optional and only needed if overclocking.

Thank you! So, ANY type of overclocking? Or just real instense Overclocking like mentioned above (Liquid Nitrogen). I just plan on changing RAM and Processor speed a bit.

 

[Coolsmoke]

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.
