Tom´s Hardware escribió:When we asked the PCI-SIG, we received the news that for the first time, PCIe will get a massive power increase at the connector. Solomon couldn't recall the exact ceiling because member companies have proposed several options. Solomon stated that the minimum would be 300W, but the ceiling “may be 400 or 500W."
Even with the minimum 300 watts, there is more than enough power provided by the edge connector to run a GeForce GTX 1080 (reference design 180 watts) and Titan X (250 watts) without an external power source. PCI Express 3.0 provides a maximum of 75 watts thus far, though many slots support the default 25W. The rating for a x16 lane card comes from 3 amps at 3.3 volts and 5.5 amps at 12 volts, which is a rating that dates back to the introduction of PCI Express 1.0a in 2003.

PCI-SIG reached out to tell us that the power increase for PCI Express 4.0 will come from secondary connectors and not from the slot directly. They confirmed that we were initially told incorrect information. We have redacted a short passage from our original article that stated what were originally told, which is that the slot would provide at least 300W, and added clarification:
PCIe 3.0 max power capabilities: 75W from CEM + 225W from supplemental power connectors = 300W total
PCIe 4.0 max power capabilities: TBD
New value “P” = 75W from CEM + (P-75)W from supplemental power connectors.
