SPECS:
i5 4690k
GTX 1070
8GB RAM
1TB (idk rpm) HDD
500w PSU

So I had an old PSU that gave out on me when I installed my 1070 (had a 960 before hand). Idk what wattage the old one was since it was used by a buddy of mine when I originally built it (2014 I think?). But everything seemed to be alright when I first installed the 1070 (the middle of last month) and a couple days later I think the computer gave out in the middle of playing The Division and wouldn't restart. It would turn on for 1 second with all the lights and stuff but then go right back off. So I thought my PSU finally just had it's time and gave out. So luckily I had a spare 500w and put that in and everything has been working just fine. My only concern is that recently my new PSU has started to be extremely loud when I play most games (started about a day or two ago). I'm afraid I'm over my wattage limit and I heard having my PSU give out the way it had could have caused damage. I plan to get a 750w PSU tomorrow and won't run any games till then. But I just wanted to know has damage already been done to my computer? Everything seems to run at a good fps like before but I am really afraid I lost performance in some way with my old PSU going out the way it did and my current one acting up. I don't have all that much money to spend on PC parts anymore so I just wanna make sure I am doing the right thing. I haven't really had any performance issues aside from google chrome occasionally crashing/freezing and the loudness of my PSU. Any info is appreciated though, thanks.

It could be a bearing yes, I've had that happen before. In my case it was a 12cm fan and I bodged up a case fan to fit. Actually I cut a molex to 3 pin fan adapter in half and joined the 3 pin socket to the to the plug off the old fan to make a custom adapter. That way I could plug a standard case fan in.

You only actually need the black and red wires in most cases, the 3rd wire is just for speed sensing.

well, i believe the only way to know if you are going to lose performance whit the 1070 is to try it again :V. But, i dont really think that could happend. BTW, what about temps?

Temps have always been fine, even with the original crash. Just don't want it causing more damage if it already did then. Rather be safe than sorry. But is there any tests to do to see if my GPU has any damage?

It's probably fine. When you say loud, is it fan noise or something else? and are you sure it's the PSU and not the graphics card?
could just be some dust or fluff that needs cleaning out and the fan is running fast to compensate for poor cooling.

If it's a different kind of noise then that's a worry for sure.

Nothing is blocking it, brand new so no need for cleaning. First thing I did was check to see if it was GPU or PSU and its definitely PSU. It only kicks up when I do intensive stuff and slows back down in idle.

I've heard that the fan should always be silent on a PSU (nearly). Only weird thing I noticed is that PSU loudness happened recently about 2 days ago (the new PSU was installed on the 28th of last month). The newegg wattage calculator was the only one that said my build was over wattage. Two other sites said I was quite below.. not sure what to go with. I don't have warranty info cause I bought the new PSU about 2 years ago but never used it until recently. Could it just be a bearing in the fan? I don't really wanna risk pushing my build if it's not supposed to be compatible.

Only issue with that idea is that why would the sound go away in idle. If it was a bearing, wouldn't it always make the sound?

You've mentioned a few Power Supplies, and their wattages, but not once the Make or Model.
Not all PSU's are equal, and one company's 500w can be completely different in quality than another's.
It comes down to design and quality..how the power is divvied up and how good are the components.
A failing power supply may or may not take out PC components when it dies. The components don't sort of die though, so you got off lucky the first time.
By the sounds of it now, your current PSU is working fairly hard and it's probably heat causing the fan to crank. I'd worry about it's quality as well if the fan sounds cheap and freaking out.
Have a look at this PSU Tier List : http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html

Mines a bronze EVGA 500w power supply, the other was blank and old so I have no clue. I'm looking for something on the cheap that is good and at least 550w-750w if possible.
