Long story short…
I threw together a little miner with some pieces I had laying about, but I always knew I’d be close to the bone in terms of PSU usage, however it looks like I was TOO close.
After the EWBF CUDA miner fires up and the GPUs kick in, the entire PC powers off.
I set --intensity 1,1 in start.bat as a test and it still dies.
Is there anything else I might try… short of getting a new PSU
