Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
I suppose low voltage could cause data corruption during disk writes trashing your hard disk or improper component operation that might lead to some sort of hardware failure. I also think this very unlikely as all motherboards have voltage monitoring circuits that reset the system when they detect a low voltage.
I think low voltage protection in a power supply is more marketing hype then a real feature. A power supply cant monitor cpu core or dram voltages.
