how much kilowatt does my set up needs to run this mining rig?
it depends on the brand/GPU type, AMD / NVIDIA has a difference on
power consumption.yes maybe
Max 1.6KW will be needed
Unless you want to run inefficient mining rigs, 1.6 kw is a WRONG maximum amount.
If you really want to step out of the amateur "hobby" mining niche you need ffficient mining rigs which need to run with a minimum of 13 GPUs per rig. The better the GPU on those rigs the higher the power consumption. For maximum efficiency you would need high powered GPUs that give the best hashrate to power consumption ratios (1080ti will do). To run those, a 1.6kw power consumption surely won't cut it.
