Totally agree and AMD seems to be a good citizen in that regard. Well, at least since the RX 7000 series.

The values change slightly each time they are plugged in, which indicates the general deficiencies of the plug connection (clamping surface, contact). Added to this is the voltage drop, which also depends on chance.
The shortcomings of the 12VHPWR connector, in particular the uneven current distribution through the cable and connector, can cause unbalanced loads where individual pins are loaded more than others. These local overloads lead to increased contact resistance and heat generation, which under certain conditions can cause thermal damage to contacts and cables. In addition, by dispensing with active balancing and splitting the power supply across several rails in the board topology, NVIDIA has itself abandoned possible protective and corrective measures. As the cards directly take over the faulty distribution of the input side, the power load remains uncontrolled, which can lead to escalation under the wrong conditions.
This situation shows how several factors can interact: The inadequate plug connection as a starting point, the resulting thermal issues as a potential symptom, and the lack of protection measures on the board as an untapped opportunity to remedy the situation. Although such problems do not necessarily have to occur, the system remains susceptible to this concatenation if the load and the external conditions coincide unfavorably.
Eh... I'd probably direct wire the charger, but 50A isn't that crazy and just seems that way because at 240V it's a lot of power. It's not more than a 5090 draws really. Half the 16 year kids with their new license and and $1000 beater are running straight to Crutchfield to buy 2/0 cable and a couple 2kW amplifiers to pull hundreds of amps and keep their whole neighborhood up for hours at a time and they hook that crap up with nothing but a screwdriver and a dream.Slight tangent. I just had this YT story suggested by the algorithm:
It seems that NEMA 14-50 (50 Amps) outlets used to attach home car chargers, are melting.
50 Amps is serious current, where you need perfect connections.
Suggestions are Direct wiring is better, if not, make sure you get an industrial grade outlet.
Not a new idea, they've done it before with the 4090. What all AIBs should do with the 5090.Galax has a 5090 with dual 12 pin connectors in their lab, it's not clear if they will, or are allowed to ship to customers, but they should. It also appears to have 5 shunt resistors for measuring incoming power:

Why would they not be allowed to ship to customers?Galax has a 5090 with dual 12 pin connectors in their lab, it's not clear if they will, or are allowed to ship to customers, but they should. It also appears to have 5 shunt resistors for measuring incoming power:
