Came to here because looking to get a new psu.
No sure why it under "TIER E - DANGEROUS" XDD
but I got myself Corsair VS650 back then in 2014 and it only started to occur problem (power on problem) last month after I changed RTX 2060
My system:
i7 4790, 16GB DDR3,
from GTX 650 > 950 > 1060 > 2060
PC powered on at least 6 hours per day now, back then 24/7 in my 3 years of college year.
Thanks "TIER E" psu for serving me for more than 6 years. XD
