Is my PSU failing?

Motherboard: Gigabyte x99 ultra gaming rev 1.0 "2011-3" ( fa6 bios )

Cpu: HASWELL-E Intel i7- 5820k
Ram: G.SKILL TridentZ Series 16GB (2 x 8GB) Memory Model F4-3200C16D-16GTZB
SSD: samsung 500gb evo
PCU: Cossair RM850x watt
Cooler: Corsair Hydro Series H100i V2 Extreme Performance Water
Graphics card: Msi GTX 1070

So 3 months ago i had water damage in my basement, it was near my computer. My computer was on the ground with the carpet soaked. However my computer worked fine 3 months after it happened. Now last week my computer turned on, beeped and than didnt post. Today it completely refuses to stay turned on for more than 8 secs, and it turns off and repeats.

I have tried brand new memory sticks and it didn't change anything. Tried clearing he CMOSI don't visibly see any dry water marks inside ( looking through the air holes). I tried unplugging everything and everything works, it just wont work for more than 5 seconds. This computer is only 6 months old, and i built it myself, it worked just fine for all that time till 1 week ago.

I looked up the beep codes for my Motherboard and it told me that it was memory failure, and then when the computer started to beep continuously, it surely was memory failure.
I think i've also noticed the "Cosair" logo on the water pump is not its brightest. Whenever the computer shuts off on its own, the Logo blinks brighter and than darker.
Could it be a bad PSU?

Maybe the PSU was infiltrated when your Basement was flooded being the lowest hardware part in your case. If there has been corrosion within the PSU then don't use the system till you know for sure.

The only 100% way is to swap out the PSU with a known working unit of the same Wattage or higher.

Nope. I got a new psu and it works with my newer built pc with a i7 7700k. I tried literally everything besides a different cpu. It has to be the cpu at this point because gigabyte told me the motherboard works fine.
