Thank you very much for all the feedback guys. If 2x850 does the job for 6x 1080ti, will 2000w do the job 8x 1080ti or should I go for 2400w?
Also, how much RAM would I need for the rig of 8x 1080ti? Will 4gb be enough or I need 8gb?
Thanks again.
Sure it'll "do the job" but if you can afford it, it's always better to leave as much buffer room on the load as you can.
