ZOTAC RTX 5090 12V-2×6 connector completely melts with below-recommended 850W PSU

[Strange bird]

There's also no reason to spend $150 to replace a perfectly good 5 year-old PSU because nV and PSU companies colluded to change to a negative net-gain "feature".

I have a relatively little-used ROG Thor 1200w that is using the 4x PCI-E 8-pin to 12v-2x6 on this same Zotac 5090. Works just fine with no temp issues at the connection, just like it does with thousands of others.

I thik the issue with most of these adapters, when used with a proper GPU, is they get torqued easily when the case panel is added back on due to the extra cabling protruding from the side. In my case, I don't even try to put the left case panel on since leaving it off helps with airflow and my PC sits in a desk hutch anyways.

I bent my adapter as much as I could to close the side of the case, now it doesn't get stuck.It does not touch the side of the case.
The other problem is that some cards are much larger than mine, so bending the adapter probably won't help either. It depends on how much space you have in your case because they're not all the same.
Either take the case side down or buy that 90 degree adapter.

Corsair has 90 deg. cable, so you don't need to buy an adapter.

I would need to bent cables considerably to fit the panel on -- not worth the risk. I've got a Corsair 4000D which I consider pretty big. I suppose I could get one of those fat-boy cases, but call me old fashioned, I think a proper desktop PC is rectangular, not square.

We already know that the connector itself is stupid. We are dealing with enormous amount of power flowing through it and there is no load balancing safety system. Electricity goes through where is the least resistance and if there is something wrong with some of the pins or wires, it puts more stress on the others because electricity favors that route. This is incredibly stupid design.

If we want to deal with a lot of power but want to keep the design simple, then there should only be two thick wires, hot and ground, automotive style. Trying to spread the same load between multiple thin wires without anything that can control it and share the load between them is a gamble. It can work until it doesn't because something went wrong during the installation or just the wires or pins were bad.

Typically in a situation like this you dont load balance, you just use larger safety margins. Larger connector, more pins, different materials or mechanical design, etc. Load balancing is extra complexity that is probably not needed.

okay, w/ the 12V-2x6 going on fire and the fire stories are spreading :

is it safe if we go back to the 8 pin interface w/ the video card is RTX 5050? It is the 5000 series, but the pin connection is only 8 pin. So I'm thinking for safety reason, protecting my PSU and motherboard, that 1 of these 2 will work:

Asus RTX 5050 8 GB of RAM

to cut to the chase: is the 8 pin totally safe even in the 5000 series?
