I seem to remember that Phoenix is no longer recommended because of potential security issues or something like that. It has been removed from the latest NiceHash miner.
BTW I very much doubt the profit that NiceHash states because the power usage is calculated as the power used by the GPU only and that is not the only power used by a PC. My GPU (GTX1660) is using according to NiceHash & GPU-z ,57 watts, only 20.88 MH/s, memory slightly overclocked to 4650 MHz down from 4950 with memory controller use rising from 90 to 95%, GPU limited to 1215 MHz and 0.7 volts. I use a Seasonic 550PX platinum PSU which is highly efficient and my PC is currently pulling ~ 146 to 151 watts from the wall !!! Therefore the profitability calculator is way off IMO. I did manually change the Benchmarked power to a higher value to more better represent the power that my system pulls from the wall. I put around 125 watts in many of the benchmark power boxes to closer represent my system power for a closer profit calculation. 125 watts seems low now considering the power that I am seeing with my power monitor which my PC PSU plugs into. Since it has been connected it has used 7.48 kWh of power in 81 hours. Power is expensive in the UK and that has cost me £1.10 (~$1.53). On the plus side my GPU temp is only 35C with fan @100% with GPU@100% usage. The hashrate rises to just under 22 MH/s when my GPU is running at full speed of 2010 MHz which is the default for my MSI GTX1660 Armour OC. The power usage rockets to around 190 watts! Less than 10% increase in hashrate for a 25% increase in power. My graphics card uses crap Hynix ram which is why the hashrate is fairly low.
BTW I have noticed that benchmarking at least getting the power figures fails if any other GPU monitoring is running such as Afterburner or GPU-z.
The only issue with these power monitors is that they themselves use power, 20 VA it is rated at, rather than watts.
[EDIT] power from wall is down to 124/125 Watts after restarting my browser which was using quite a bit of CPU ~25% and power. I will have to remember to keep restarting my browser to cut memory usage and power. 32 GB of memory so memory is rarely a problem unless one or more of my many running browsers, 4 ATM but 5 on occasions, gets to 10+GB.
