Recently, I built a new pc, using a slightly older power supply I had in my other computer. I have had the power supply for nearly 2 years with zero problems. Even for the first week of running my new computer, there was no loud whine coming from the psu. Then when I moved the computer to a different building, not far away, I began to hear a loud whine from the psu. I used to not hear anything while it idled, and it was only slightly loud when running demanding games or programs. Now I can hear it all of the time. And when I load up demanding games like Grand Theft Auto V, the sound is so loud, I can hear it through my head phones. At first I though it was the pump or fan on my EVGA GTX 980ti Hybrid, but when I went to investigate, I noticed that the sound was considerably louder near the psu.

PC Specs:
CPU: i7 4790k OC 4.8GHz
RAM: Corsair 2x 8GB @ 2400MHz
MOBO: ASUS Z97-A-USB 3.1
GPU: EVGA GTX 980ti Hybrid 6GB GDDR5
SSD: Samsung 850 Pro 512GB
HDD: WD 4TB @ 7200RPM

Any help on this would be much appreciated!

Usually when you operate on your system your unit has to do double duty in order to maintain clean power being delivered to your components. The by product of all the maintenance is dubbed coil whine. If you're taxing an old PSU that had seen similar power drawing as well as some warm operating environments then the capacitors may have degraded. Now if the issue wasn't seen in your old crib then the culprit can and will be pinned down to the wall outlet. If you've narrowed it down to the PSU and not your GPU then try and see if your warranty is yet intact and ask for an RMA or that you can get an electrician to look at your crib's wiring or possibly both.
