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 know a computer PSU can take 110-220v AC input, but I see a 125v rating on the power cord. If I'm going to use this computer overseas, should I get other power cord?
A PSU can only take 110-220(should be 240...) IF the PSU specifies that it can. Do not ever ever assume it can handle both. Cords do not matter, the rating on the PSU/power adapter [of anything] is what matters. As for Blue Fox's mention of the plug on the end, all you need is a cheapo $1? prong adapter. Again, do NOT assume it can do 110v-240v.
