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 think that should be fine. I had 2600k overclocked to 4.2 ghz, 1 ssd, 2 hdds, 2x 680 overclocked heavily. And it wasnt even using over 600 watts. You can purchase Kill-A-Watt and see how much power it really uses
I have one of those but I wasn't sure if the power being pulled from the wall was the same as the power output of the PSU given efficiency, rectification and what not.
