The PCI Sig committee does put strict power budject restrictions on both PCIe 16x and PCIe 1x - at S3 we plan to fit within these guidelines!!
A 25W PCIe solution , 16x or 1x is possible using GammaChrome products. We are not disclosing any final configuration plans of our PCIe board offerings.
I would be interested in your feedback on application needs - why do you want a PCIe 1x instead of 16x (I think I know - but I would like your answer )
Thanks,
