The first one is better as it has 19A current on +12v rail compared to second's 14A. Either of them are not that good for your system go for a 500w branded psu corsair, seasonic, xfx, else your risking your system.

I agree.

The sound is probably coil whine and not the biggest of issues, however it is imperative you replace it with a dependable psu from corsair or another trusted manufacturer that ghost listed
