Graphics Card Power Cables

[rainbowtonic]

Hi guys,

 

I have a corsair tx850m semi modular power supply and an RTX 2070 super. I hate that the power cable slots for the GPU are 8 + 6 pin because the extra 2 pins hanging off the provided cable from corsair look really ugly. I'm looking at getting a braided cable for it, but my question is can I plug 1 8-pin to 8-pin from the PCIe connection on the PSU to the GPU and 1 6-pin to 6-pin from the peripheral/sata to the GPU? Or will i run into power issues?

 

Thanks :)

I'd avoid using anything other than an actual PCIe power cable to attach to your GPU. A SATA power cable isn't rated to the same power draw as a PCIe cable. You could get a braided 6 to 6 pin connector and hide the 6+2 pin cable out of sight so you don't need to look at the +2, like you would do with the 8 to 8 pin you were already planning on.

No.

 

Because the 6-pin on the PSU provides +5V and +3V and only has two +12V pins.  The PCIe/EPS12V 8-pins on the PSU provide four +12V and four ground.
