Graphic Cards Nvidia 4000 series owners - safe to use 12VHPWR adapter?

Just bought the Zotac 4080 super trinity OC. There was this whole episode of 12VHPWR connectors melting a while ago. I mostly remember that being a case of cable not fully plugged in.

Is there is still any major issue with the 12VHPWR connector? and is it safe to use the bundled 3x 6+2 to 12VHPWR adapter supplied with the card?
 
The melting occured when the 12VHPWR connector was not fully inserted into the GPU or the wires were bent against the side panel. So if you have a narrower case (less CPU cooler clearance), you need to be wary since bending increases resistance, which causes heating and melting of the connector or the cables.

For extra peace of mind you could buy a digital thermometer like below and stick the probe to the connector and monitor the temp while gaming. But this connector has a design flaw, and was one of the reasons I jumped to Team Red. Might be less of an issue with the 4080 since it draws less power, so less heating at the connector/melting.

The 3x PCIe ----> 12VHPWR pigtail shouldn't be a problem on it's own.

Were you the one who took it in a great (read unbelievable) deal recently from fk?

Good to hear that you got the right product and everything went smoothly. Congrats and enjoy!
 
I’m on a 5700x3d and a pcie 3.0 board (b450 MSI tomahawk) with 3600mhz ddr4 ram. Gamers nexus did a video comparing 4090 on pcie3 and pcie4, and found the difference to be marginal.

There won’t be a material difference right? I don’t really want to upgrade the system to b550 or b650, potentially requiring cpu/ram change on the latter.
 
Only if you play at 1080p and can tell the difference between 300 & 305fps

Your current bottleneck is likely the monitor Hz itself

And there will always be a bottleneck somewhere. Don't worry about it, just enjoy gaming

Just make sure its properly inserted. I have built 3 machines with 4000 series RTX cards since sept last year. All running 12vHPWR connectors. 2 using ATX 3.0 direct from PSU 12vHPWR cable and 1 using PCI E to 12vHPWR adapter that came with the card as it was older 1000W PSU. No issues so far. Avoid using 3rd party cheap 90 or 180 degree adapters for now and you should be safe.


Also almost every single failure is attributed to 4090s and their absurd power pull which heats up the connector contact if not properly inserted.
 
The default inbox connector should be fine.. just make sure there isnt a extreme bend on the cable from the gpu end.

Also avoid aftermarket cables.. the cablemod extenstion cable which was bieng used with my 4090 almost burnt my system if i hadnt come home early one day.

Decided to buy a ATX 3.0 psu the next day itself.
