Oh you are right these PCIe power connectors can only draw 150W, so you would need 4 of those for 4090/5090. I guess that makes sense then to create a new standard for it actually, hopefully they can make a newer revision of that connector that makes it safer.
In theory with the new standard you can have a single cable from the PSU to the GPU instead of 4, which would be a huge improvement. Except if you use those and then your PC catches fire, you will be blamed by the community for it. People on the reddit thread [1] were arguing that it was his own fault for using a "third party" connector.

- numpad0 2y agoThe old Mini-Fit takes 10A/pin, or theoretically 480W for 8 pin. Existing PSUs would not be rated for that much current per the PCIe harness, so the connector compatibility has to be intentionally broken for idiot proofing purposes, but connector wise up to 960W before safety margins can be technically supplied fine with just 2x PCIe 8p.
- slavik81 2y agoEPS is practically identical to PCIe, just keyed slightly differently, and it can handle 300W. It's used for the CPU power connector and on some data centre GPUs. I've never been clear on why it didn't take over from the PCIe standard when more power was needed.
