8pin and 4 pin on X570 motherboard

[Gastarbeiter]

Hi all

 

I am planning to get the MSI X570 Tomahawk motherboard, which has a 8pin and a 4pin pwer connection for the CPU

My power supply has two 8 pins. Do I need to buy an extension that will split one of the 8 pins to a 4+4?

My PSU:

the 8 pin eps usually breaks to a 4+4.  so for the most part, you shouldn't. 

though any reason to go with a 750w unit? what are you powering exactly?

Both 8pins are solid 8pins, they do not break in to 4+4

 

The PSU is left over from my previous system. I will be powering a Ryzen 7 3700X, 16GB ram, 5 fans, 3x drives (1x M.2, 1x SSD, 1x HDD) and a Vega 56 temporarily until the new GPUs are out

ah then that wont fit. 

as for a splitter, i can't find anything that's an 8 pin to 4 pin.

either way you don't need it, a single 8 pin easily provides 384w of power and with a 3700x, you wont come near that.

Thanks

You only need to use 1x 8-Pin connector. The second one is only for extreme OC.

you don't need the second 4 pin connecter as the users above me said 9I did just test it now as I have a 8 pin and a 4 pin on my asus x570-e board and it still booted)

Thank you guys. I did find an adaptor from silverstone that breaks an 8pin to a 4+4. I will order the motherboard and if it doesn't boot I will order the adaptor.

No problem

Glad to help

UPDATE:

I ordered a set of white extensions anyway as I wanted the cables to suit the build

 

The motherboard worked fine with only the 8 pin but the CPU would not boost to 4.4GHz. I added the 4pin and everything works fine now.
