Aerocool is terrible, I had 1000w gold rated and the PCIE 8pins melted within a few months.
Doesn't matter what the rating is you just cannot run these shitty cheap brand PSU's 24/7 especially not to mine with.
Server PSU or EVGA T2 or P2 is all I will use from now there are other reputable brands and options but even then you generally need to go for the higher/premium range otherwise you will simply be buying them again within a year.
EVGA for me or corsia!
