Powering VEGA 56 - new builder help

Hi there,

 

I am nearing completion of my first ever build.

 

I have installed a VEGA 56 GPU and I am

now looking to power it. I notice that one the card there are two power sockets as expected. However I also notice that on my PCI-E power cable coming from the PSU has two plugs on it Which I could use to insert into both sockets on the GPU. Should I do this or should I be running two separate PCI-E power cables.

 

Apologies if this is a silly question, It’s my first build and I don’t want to damage any expensive parts 

 

thanks, Mark

Its actually best to plug in 2 separate cables. you actually lose a slight bit of performance from using the daisy chain cable.

Use two separate cables from the PSU.

Maybe I should do this too then.. got the RM550x and used the 8 pin + 6 pin on my 2070. (One cable$

 

i haven’t noticed any performance issues tho @Skiiwee29; is it a noticeable difference or should I be fine the way I have it now, or should I run that second seperate cable ?

RTX2070 will be fine. Not a high power draw card like the Vega cards are, especially if you're overclocking the Vega or using custom bios.

It has absolutely nothing to do with gaming performance!

It's because with high powered cards you can draw too much current through the 8pin modular connector on the PSU side and can melt the cables/connector.

Like this post on another forum from a user when they were using a single cable for the 2x8pin PCIe connectors required for their HD7990 graphics card...

Just use 2 Cables from the PSU to the GPU.

One might work but 2 are better due to lower resistance, lower voltage drop on the cable.
