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 am moving some drives into my gaming rig and want to be able to support atleast 6 HD's total. My specs for my gaming rig are in my sig. Will my TX650 be up to this or should I jump on the cheap Antec 850 Quatro deal?
HDs generally use about 5W under load, 10W at most. Your current setup probably uses around 400W under load tops, so you still have plenty of headroom even after adding the drives.
