I've seen the cooling ratings which are some
3060 looks a card made for mining/fighting AMD's VRAM allocation, if you need the extra 4GB of VRAM for gaming, then you need the extra Cuda's the 3060ti has, this card makes little sense outside of mining. It's going to be slower than the 3060ti but with more VRAM...
You need slightly over 4 GB of RAM for the Ethereum DAG file so a 6GB card with the fastest memory possible and low power would be the perfect mining card.
Admittedly I don't know much about mining but I do know that once you reach the min required memory for the coin then it is all about memory speed not capacity.
Don't you think the slower memory bus on the 3060 will really hurt its hash rate?
Is there another coin that you think it may be good at mining?
On the box it recommends 650w PSU.
Full system draw with the fastest CPU's is 200 - 250 even when overclocked but you will never use that much power from CPU in game. The 3060 will be a sub 200w card.
If you push big overclocks(may not be possible) you might use 450 watts but 400 full continuous draw is more realistic so a good 550 watt will be more than enough. Or a crap 650w but it's dangerous to use such low quality power supplies.
Even on the 3080, for the most part people have found a high quality 650 watt to be sufficient but it's a little too close to the limit for my liking and there are a small number of AIB cards that could trip overcurrent on max power settings.
