Yes, it's 1150W With a wattmetter on the plug (for the whole rig - 2 Platinium PSU + Mobo + CPU + SSD + 7 Vega)
Some cards are better than others, but with my settings the range for the real consumption is 130-150 W
Wich is really fair for an old card.
I know that RTX 3060 Ti or RX 5700 would have better efficiency, but they were overpriced.
I bought my Vega from 225 to 300€ in september-october 2020
You are very lucky 😜 I bought my Vega 56 and 64 for 500-600$ weeks ago but it's still a good price since they can hash 200MH on ergo, one can get their ROI back faster mining Ergo coin with Vega than mining Ethereum
