my first rig with asus strix gtx 1080ti

[POSITRON333]

hi there, I am setting my first rig with a combinations of gtx 1080 y gtx 1080ti, now I have 2 gpu running atm but have some question.   I have asrock h81 pro btc r2.0  and two (2) evga  850 watt psu.   now I want to add 2 gpu more (4 in total until now)  so I need to link the 2 850 psu and I am thinking join it with the "add2psu litter card' http://www.add2psu.com/   my questions are:

1) it is safe to join (link) that 2 psu using the add2psu card?

2) the evga 850 g2 super nova psu have 4 vga (8pin) cable slot, since gtx 1080ti use 2 cable then 1 psu allow me to connect only 2 gpu?  I hear is not good power gtx 1080 gpus  with "Y" type power connector? so I will need more than 2 psu for the 6 gpu?

3) currently using nicehash  with autoswiching coin mining  is that the most profitable?  or maybe claymore is better in term of wining.? maybe other opcion?  

thanks very much for help.

Two 1000W PSU will work and then you will need a Y splitter to have them both tie into the motherboard so everything turns on at the same time.

1 - definitely. I'm not even doing that I'm just jumping the pins and I have 100% absolutely no issues - https://www.youtube.com/watch?v=ixcWCrYpw3Y
2 - every single 1080ti i have is on Y's - no issues. I use 2 850's for 6x1080Ti
3 - nicehash is great for a beginner, use it to start then poke around and look for better stuff, read the claymore, ewbf, nemo etc threads and then you'll get a good idea of what to use. 1080ti is good on a lot of algos

@VyprBTC

Do you use Founder Edition or with two or three fans version ?

[POSITRON333]

3 fans,  I think is not founder edition,  https://www.asus.com/us/Graphics-Cards/ROG-STRIX-GTX1080TI-O11G-GAMING/

I use my 1080ti to mine ZEC and DGB skein，not sure which one is more profitable.

I think one psu 850 w is enough to works with two gpu.
