After a while of gaming I can hear the buzzing of electricity loudly going to my charger, is that normal? I have to keep my alienware plugged in to get the best performance with my dual nvidias....

Well, it is an Alienware...

 

but it could be a cooling problem. Do you have it lifted up off of whatever you're setting it on? A lack of air could cause a lot of noise.

pretty much sums up the entire thread in one sentence

There is no noise coming from the actual computer, I can hear it  inside of the wall plug...

Do you know if a normal extension cord would be able to protect it? Also how much are surge protectors?

I have these around my house, are these the proper ones?

Your average surge protector is going to be about $20, but a normal extension cord should suffice.
