Earlier this week we got some information regarding the upcoming PCI-Express 4.0 standard and while it was believed that it would deliver 300W from the slot, apparently, that will not be the case and the power delivery will remain at 75W.

The information regarding 300W was originally shared by Tomshardware.com, which got the information provided by PCI-SIG slightly wrong as the PCI-Express 4.0 will deliver 300W when combined with supplemental power connectors, just like the PCI-Express 3.0. The slot will still provide 75W and you can get additional 225W from power connectors.

While it did sound strange, it also meant that future graphics cards could draw all the power directly from a PCI-Express slot, but it would also mean that you have to supply the motherboard with additional power and while it could get you a better cable management, it is still the same thing.

In case you missed it, PCI-Express 4.0 will double the bandwidth of the PCI-Express 3.0, from 8GT/s to 16GT/s, which is a significant improvement.

The PCI-Express 4.0 specification should be finalized by PCI-SIG later this year but we do not expect to see PCI-Express 4.0 motherboards anytime soon.
