well i plan to build a 6x (or 7x gpu if possible - but i think its not with nvidia?) mining rig with gtx 1080 ti cards. if you can recommend me a motherboard, psu and cpu for it, it would be awesome.
thanks in advance
These motherboards go out of stock pretty quickly, so grab one now if you're sure you want to build a rig.
Any socket 1150 Intel CPU will work for mining, even the cheapest Celeron. If you want to use the rig for office work, web browsing, streaming video/music while it mines then I suggest an i3 from that generation.
Would the (240v)2400w delta power supply from Paralellminer be a cheaper alternative to the 1600w EVGA for a 6 card 1080ti setup??
When having a rig that need huge amount of power, i have learned the hard way that is kind of better to go with 2 power supplies. It's cheaper and when one goes bad you "limp" away with half a rig and still make money till you fix it instead of totally blacking out. It's also usually cheaper in total price. It's easy and 100% safe when done right (i use add2psu to connect 2)
