One of the biggest stories of the week was the tease of the PCIe 4.0 specification, which was said to deliver up to 300W over the PCIe port. It sounded impossible, but we thought the information was legit, considering it came from Tom's Hardware. The information wasn't accurate, with PCI-SIG coming out and confirming the real news: PCIe 4.0 won't deliver 300W over the PCIe 4.0 slot... damn.
The updated post on Tom's Hardware said: "Update, 8/24/16, 2:06pm PT: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
