Just received the first batch of APW5 PSUs and R4s. I was a little uncertain about the actual number of 6-pin PCI-e connectors it came with due to some of the images showing only 7 connectors total. I'm pleased to share that there are indeed 14 x 6-pin PCI-e connectors, as originally advertised by Bitmain. The APW5 does appear to be capable of supporting 2 R4s with a single PSU (using 220v power).
