Ok, thanks for the confirmation. I first tested it out with just one 390x connected via 16x riser, and that worked great. Then, I installed TeamViewer, shut down, connected the other GPUs via 1x-16x risers, and restarted (without a monitor plugged in. I thought I could just then use TeamViewer to connect and start up the mining software). After work, I'll try restarting again but with a monitor connected during bootup to see if the other GPUs get started.
I've got 2x 1000w platinum PSUs to power the 6 gpus. Should be enough. While testing though, I've only got the 3 connected with 1 of the PSU. I think 1000w is enough to power those 3 cards though...

No Prob.
The 390x's shoudl draw stock about 250watts each, the 280x's about 230watts or so. (as long as they are good quality cards).
'Most' 390x's you can undervolt and get back about 10-20% wattage, some more, some less.
I run all my 390's (non 'x') at 100mv undervolt, 1100/1500 settings (stock is 1015/1500) and they use 200-210watts each while getting around 29MH+ now.
Solo mining has been earning me 50% more than pool mining for the past week so I'm sticking to it. Some days I get 1, some days I get 5 blocks.
