Yes and when I set my power setting to maximum performance the noise remains consistent and when I started the game the pc tended to restart earlier

The noise is comming from the PSU and it is not that old just 2 months... when I change the power setting to power the saver the electric noise goes away when I set it on maximum performance the noise gets high.
Did a Prime95 test for the CPU and CPU didn't go past 61c the test lasted 1 hour until I connected to Wifi and the PC made a restart, did a GPU Stressing test and degree went max 76c with FurMark, test lasted for 1 hour no problems.
I wonder if it's really a high end PSU the reason I picked is because I am planing to do an upgrade in the future to probably GTX 980TI or R9 390X (to go beyond 1080p) and do some overclocking for the CPU, wonder if the MOBO would support that...

I'm leaning more on the PSU as the culprit. CPU voltages shouldn't fluctuate enough to cause a crash due to inadequate power. The WiFi is understandable because that's more of a power hog (think of cell phone WiFi draining battery). The GPU running at load didn't cause a reset...was the CPU at any load?

Rebuilding your PC you should only need a 500W PSU at minimum. I wonder if your PSU is dud. Any chance you could borrow one off someone to test it?

I did some research about your PSU, and there's quite a few results that come up with the solution being a faulty PSU from Thermaltake. I would suggest going to a store in your area with a lenient return policy and buying a Tier 1 PSU (on this list) for about 600w to see if that doesn't resolve the issue.
