1210 watts quoted "at the wall" - an EVGA 1300 would have about 10% power reserve, even my favorite Seasonic X1250s have some power in reserve.
Indeed. Some of the more common official peak ratings are in my PSU guide, although for 24/7 its still going to officially be the stated rating. That being said, I've ran many corsair PSUs past their limits in challenging conditions and they've done fine.

Only if you can run each board on two instead of three connectors, contrary to bitmains instructions.
However, they said to use two connectors per board for S5 and some people used just one successfully (with a good quality connector such that found in EVGA).

I'm using an EVGA G2 gold 1300 now with two S5s and it's running at roughly 93/94% efficiency.  Per my 'at the wall' meter.  all red VGA cables used, vertical strato setup with a box fan.  I just checked this.  Was running at like 97% efficiency when only was running one Tongue, but lot less load.

good, but it doesn't actually answer my question re using 2 cables/board instead of three. EVGA 1300 has only 8 connectors and you need one of them for controller, so that leaves 6 left for three boards in S7-will it work? I guess that we will have to wait until someone does it first (my money is on Philip since he was always a fan of evga).

Someone actually mentioned on the S5+ putting an inline delay device on the cable that goes to the controller so that it would intentionally power on AFTER the hash boards.  I thought it was an interesting idea but he was wondering if that would violate warranty even though he wasn't modifying the device just putting another device in-between the the PSU and the connection.  I personally think that should have been part of the controller design ANYWAY through firmware, by hey that's me.  It just seemed a bit asinine to have an intentionally separate connection that another switch had to be flipped to power on a unit. 

Maybe that can be in batch run 2.  (HINT HINT Bitmain)
