• 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.

Does a power supply, draw max cappacity from the wall at all times? or does it draw only what it needs?

just wondering (and i have been looking.)
 
It draws (Power computer is using) / (Efficiency of PSU).... Short answer: what it needs

seconded.

There is inherent (constant) loss, and the efficiency of a power supply varies with the amount of load that's on it... but this is more or less accurate.
