Hi,
I use a rtx2060 super and a gtx 1660ti for mining and it works well,
i have another 1660ti,
When i use all 3, I can mine fine for a bit, But when i use my Pc (like Google Chrome), it shuts down
(ive swapped cards around and they all work fine, and can mine 2 at a time well)

I use a new 850W Gold Powersupply, Thats enough to use those 3 right?
Could the issue be the PSU cable not being thick enough? What do yall think

Specs:
FX8350
Asrock Extreme4 Mobo
16gb ram
850W Gold PSU

What's the model name of this PSU?

1660TI has a TDP of 120W. Probably peaks a bit higher than that. The 2060S has a TDP of 175W, and also probably peaks a bit higher than that. The 8350 is a 125W CPU. 240 for the 1660s, 410W once you add the 2060, and finally 535W for the CPU. I tend to add another 50W for everything else, I'd expect your draw to be around 600W, probably less as chrome/youtube shouldn't load your CPU to 100%.

So what's wrong? As above, which PSU is my first thought. Loading a quality 850W PSU up to 600W is fine. Loading a cheap/junk one will result in issues. My next thought is your board. Your asking an older board to handle 75W * 3 PLUS a 125W CPU. I'm not sure how much a board should be able to handle, and I would think it could handle this seeing as it has the slots, but perhaps due to the age it can't anymore. It might also be a driver issue as it supports CF/SLI, but perhaps it only handles 3 cards if they are AMD cards, not Nvidia like you are using. You might need a bios upgrade to handle what you want.
