With my 210-GQ-1000W PSU, I have 6 VGA cables (and 6 vga sockets on the psu).
 
Two of them are 8 (6+2) pin cables, and I am using both of these to power my RTX2070.
 
But then there are also 4 further cables - these each have 2 x 8(6+2)-Pin PCI-E plugs at one end. (i.e. the same as the previous two cables, but with an extra 6+2 plug daisychained on the end).
 
Can someone please explain what they are for?
For example I assume I could use one of them as a third cable for a 3090 (the daisychained plug would be hanging loose, unused), but is it possible to actually use just a single one of these cables for TWO of the ports i.e. both daisy chained plugs, to power my 2070, or to power two of the three slots on a 3090?
 
Thanks for any explanations.
 
 
 
 
 

Thanks bob16314, that's good to know, and means I won't have to add a third cable if I end up with a 30** with three sockets -  I can use one of the split cables and one of the singles, (assuming they're the same style connectors).

You can use a single cable that splits off into two 8(6+2)-pin connectors for your 2070 or use two sepearate ones.

Bob, thanks; that's the answer I was hoping for but, honestly, not the one I was expecting.
For the curious, are you able to explain how this works?
Because all the VGA cables I'd seen before had one connector for the PSU and one for the GPU, I always assumed that the current from an individual PSU connector is limited and insufficient for powering, by itself, a 2-connector GPU.
Is EVGA pulling some kind of internal autosensing trick with this cable, or can all PSUs do this, given a cable with two GPU connectors?

It's the card itself that senses whether an 8-pin or a 6-pin PCIe Connector is plugged into it and regulates the power draw, the PSU just provides power and ground..The PCIe cables/connectors are rated for the load, however, Seasonic recommends using individual cables for cards above 225 Watts..An EVGA 2070 is a 215 Watt card.
 
That help more?
