Baikal contacted me a couple days ago to confirm shipping details for my Giant-B order, "As it is getting closer to the shipping date, I am here writing to you for double checking your delivery details."

I already have these extra NIB PSUs on hand not being used, so my plan is as follows:
EVGA 1200W P2 (6 VGA power outputs) for Giant-B x2.
and/or
EVGA 1600W T2 (9 VGA power outputs) for up to Giant-B x3.

Will require 3 VGA power cables for each Giant-B since EVGA includes a bunch of 8-pin from PSU to 2+6-pin w/ 6-pin cables.
