I also saw that very informative Gamer Nexus video.
 
Keep in mind the bending on the adapter plug is severe bending close to the plug as when someone is trying to squeeze it into a tight space.
Which then causes an increase in resistance on the plug pins.
 
And most importantly it only occurred when constant max current was applied for 10 or more hours in a testing situation. That's 55 amps (660 watts) for 10 or more hours on pins misaligned due to bent cables. I can't think of any gaming session that would draw constant power for any length of time. It is constantly fluctuating load.
 
Sure it needs to be addressed but I 'm sure it would never come up for me. They need to make tighter female connectors to hold the pins tighter along the whole length of the pin. Or bigger pins.
 
However, the 30 connection cycles is a mystery to me.

Since the 40 Series cards have not been officially released, I can't give you a straightforward answer on that.  However, the purpose of the adapter is to work with existing power supplies that do not have the newer 12VHPWR cables.  As long as the adapter is installed properly, you shouldn't have anything to worry about.
 
I would be surprised if you don't see more than a few reviewers test current-gen power supplies with the 40 Series when they release to answer this question for people.  I'm sure we'll also say something directly about compatibility at some point, as well.




Yes, I'm hoping the reviews touch on this but given the fact that both the FE and AIB cards will most definitely be OC'd, the added headroom is crucial and so a 1600W PSU should suffice, but I'm not sure of the connector/adapter situation. Pushing 3x 8-pin to one adapter seems sketchy to me.
 
I'm hoping the reviews really push their samples and not test the 4090 at stock clocks/power at 1080P like most of them do. :rolleyes:

I thought I heard that the higher OC'd or high OC capable cards will have 2 12+4 pin connectors. Anything over 660W will demand it. I would say anything over 600W for a safety margin which would give a 5 amp buffer.
 
I heard reviewers say that Nvidia is not enabling overclocks that high until more PSU makers have caught up to the needs. I have no idea if that's true.

The only thing i would really start to be worried about are these ridiculous 12+4 to 4 x 8pin PCI-e adapters, there's a lot of controversy floating a round with there lifecycle.

Since there is some sort of misconception regarding the lifecycles of the adapters, let me point out that the 30 cycles limit is on the 12+4 12vhpwr connector. This is regardless if you use an adapter or or not.

Nvidia explains PSU requirements for GeForce RTX 40 series GPU


I came here earlier to post the same thing. Glad that you beat me to it.
 
Now maybe everybody can stop speculating and worrying. But somehow I doubt it
I hope the Youtube reviewers see it.
