That is the point of the article.
The problem my friends has is that he is rendering video so he has a high performance Sas host adapter on the same PCI bus as the GPU. He upgraded both hoping the 5090 would play nicer with the sas adapter but he can't pull full disk bandwith and render images at the same time. Maybe it's ok for gaming, not for compute and writing to disk.
The thing with power supplies, they continue to provide enough power long after they lose the ability to provide clean power under load. Only when they are really on their last legs will they actually stop providing the rated power. I have seem a persistent networking issue resolved by swapping a power supply. Most of the time you don't test a power supply under load to understand if each rail is staying where it needs to be.
