Zotac GTX 660 Buzzing Noise

[PotatoKing]

Every time I open a game and try to max out the settings - 1080p, high Anti-Aliasing and Texture filtering my Zotac GTX 660 would start making a buzzing noise.
I ran many games at a max settings to test for the buzzing and 80% of the games would cause it. I would hit a max temp around 60 C with the fan turned up to it's highest setting and hit a max voltage of 0.962.
One game I ran was Metro: Last Light and another problem was about 15 minutes into it some of the NPC's or objects would blink blue for a split second this would happen at a rate of roughly one every 3 minutes. I don't know if this is a hardware or software problem a google search comes up very little. I didn't turn on Anti-Aliasing on Metro Last Light because I heard it cuts my FPS in half.

I ran a google search about this and found that someone fixed it by getting a better PSU. But for the specific case in the video his PSU was 480W vs. my PSU which is a 585W.
I found another video with someone who had the same noise but he had a 750W PSU. In the 2nd video he fixed it my RMA the card and some people in the comments said it is coil whine, a normal noise.
I asked my cousin who has built some rigs and he said to RMA the card. He said I should find a GPU that works best with my system that I shouldn't work around the GPU by upgrading my PSU and I should find out if it's a common problem with the GTX 660.
I'm worried about the noise indicating a problem like the PSU is getting overworked cutting it's life span or the GPU is defective but I don't know.

My specs:
i7-3770
8GB ram
120 SSD
500 HHD
Windows 7 64 bit Home Premium
One DVD-DW Drive
2 80mm fans

I brought the rig from these people but installed the GPU myself.

When I was customizing my rig from them I looked into how much power I would need and some of friends recommend this so I entered my specs from above set the Capacitor Aging to 30% and got 440W now I was a little suspicious of that number because I was reading that people with 460W PSU were having problems with their GPUs locking up under a load and so I looked up how much wattage my CPU and GPU would use under stress.
What I did was recalculate my need wattage by using the PSU calculator but leaving the CPU and GPU section blank it gave me 199w then adding in the wattage of my GPU under stress 239w and my CPU under stress 166w and it gave me 603w total used under stress. But my cousin told me after I got the computer that I need a 30% lead on my PSU so I'm thinking that I might have gone cheap on the PSU and it is now backfiring. It might be my amperage for the PSU are too low. On the website it said I have two 12V that can do 19A and 20A but when I look on the PSU itself it has a sticker that gives DC output and said it only has one 12V at 15A max.

I don't know if I'm shooting in the dark or not that's why I'm coming here wondering if I should upgrade the PSU, RMA the GPU, or is there no problem. My RMA for my GPU is going to end by June 5 so I need to figure everything out by then.

Below I am going to re-link everything encase there was a problem or if people didn't notice the links in the text.

The psu, its a budget HEC unit, it probably wont live up to its rated power. cheap units often overrate their power, or rate it as a "peak" power rather than continuous, and no telling what amount of ripple and noise. Get a quality brand like Antec, Seasonic, XFX, corsair. those brands pretty much always reproduce their rated power and above in testing by competent psu review sites, like jonnyguru and hardwaresecrets.
