The article itself clearly states there is nothing particularly alarming about these numbers and that they fall within existing standards. The headline us unnecessarily alarmist.

This isn't actually much of an issue.

Although it is frustrating that when Nvidia regularly technically breaks the PCIe spec, people don't really care. AMD did it with the RX 480 and everyone from written media to half-informed youtubers were out to get them over it.

Market-leader advantage I guess.

It feels like the only talented engineers left at NV are the team who designed the cooler for the 5090. Everyone else cashed out at the 1T plus valuation, and it shows in what they were able to accomplish with a significant bandwidth, core increase and 30% power budget bump. At some point "we'll sort it out with software" hits a brick wall.

Other than that, those spikes are unremarkable and within spec. Connectors are still going to melt tho, 550-600w sustained is a lot of power.
