You might need a bit more ram I would upgrade that if you are running 2x 1080 TI, and also you will DEFINITELY need a better PSU for those GPUs. 1080 ti is very power hungry. As for the mobo I'm not too knowledgeable. Worth a try at least. With mining most of the time it's a grueling path of trial and error.
Definitely a new PSU and of course throw in some capable GPU's, I'd start with 1060 's while you are starting out. It's a myth that you need gaming or mining motherboards
I use a crappy matx motherboard with one PCIe x16 and two PCIex1 and a cheap PCIe expansion card I easily run 6 cards. You don't need top ram or processor either mining is GPU intensive not CPU, RAM or disk intensive.
My PC specs.
Motherboard : gigabyte GA-M68MT-S2
2 PCIE slots : 1 PCIEx16 & 2 PCIEx1
Processor : AMD Phenom ii x6 1045T
Hard drive : 1TB HDD
Ram : 4gb
PSU : 200W
I am going to buy 2 asus rog strix gtx 1080 ti OC will it work on my built ?
Do I need to modify or completely upgrade to a new system ?
Yes, it would work but you get PSUs 80+ gold/platinum, 1080'tis has TDP 250W. I suggest you buying PSU have 1000W or 1200W and RAM 4GB is enough
you need at least 600w for 2 1080TI's, and at least another 150w for the rest of your system. For cushion and stable run, a psu of at least 850 W with minimum Gold rating is recommended for your proposed setup.

Yes, you can. Need increase ram to 8 gb and ofc new PSU.
What cards ? max 3 on this mobo, so it can be, for example 3 1080.
Before setting up my rig I am doing as much research as I can. And I found upon setting up a cheap mining rig.
A cheap hp server psu 1200w and the manufacturer may have been made it very stronger so as to run 24/7 for server pc.
Also we can find online the conversion kit from psu to 12 pci 6 pins power slots with cables from 6 pins to 6+2 pins for the 1080ti 8x2 pin power slots
This 1200w psu will be the second for just to power up the gpus and risers while the primary psu 200w will power up the motherboard.
I hope this setup will be a cheap and a better one ?
