Zotac Rtx 4080 Super upgrade for DellT5820
Hi there,
I’ve got a rtx 4080 super that fits in my T5820 with 950W PSU. The GPU has a 3x8 pin connector but the Dell has 2x(6+2) connectors. How to sort this out? 😓

Use Dell 0G22MM dongle. It convert one 8-pin to dual 8-pin (6+2).

@Chino de Oro thanks! I will get it.
Do you think that the pc doesn’t boot after uninstalling the rtx4000 drivers and swapping the gpus (without installing new drivers yet) is given by the missing cable?
If I place back the rtx4000, even with no drivers installed, it boots.
I tried to plug the 4080 with only 2 cables as many writes that even 2 is fine if you have a good PSU…

Just un update, I’ve got the Zotac rtx4080 super installed, well fitting and running.
Thanks for helping with this!
Now I have to sort out how to connect my huion tablet with the usb-c cable (power + vid) as It seems I do not have any USBC plug like this onboard, even if I’ve got 2 plugs on the front panel and the dell thunderbolt pcie module ….
