Hello, This is a relatively new build, within the past 30 days. System ran perfect for the first few weeks. My first self-built system in many years. I do have experience with building systems, so I follow the basic steps like a wrist-strap ESD protector, never place components on the ESD bags they come in, etc...

Here's the problem:
With random use (either idle or watching YouTube or playing a basic game on steam such as Star Trek Online), my system loses power. As if I pulled the plug out of the surge protector. Only the tower, not my speakers or displays, so I do not suspect the surge protector. (Also, central FL has been in a drought. No lightning storms in recent history.)
When it loses power, the system tries rebooting itself constantly, with failures at different lengths of time, while I can hear my PSU "clicking". Until I use the power switch on the PSU to stop power, it will continue. After leaving the PSU switched off for a short time <60sec, the system will boot up normally, minus a notice in BIOS that the settings have been reset to default. (No bother because I am not over clocking anything at the moment, everything is in default settings.)

Please see my attached video, to witness the failure.

My system specs:
Motherboard: MSI Z270 M7
CPU: Intel i5-7600k LGA 1151
GPU: Gigabyte Geforce GTX 1050Ti
Memory: Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3200MHz
PSU: Corsair RM Series 850 Watt ATX/EPS 80PLUS Gold
SSD: Samsung 850 EVO - 500GB
CPU Cooler: Corsair Hydro Series H100i v2

My thoughts:
The last component I installed was the GPU. The system ran fine before that. However, it only "ran fine" for a few days before installing the GPU and even post GPU installation, the crashes are random enough that the system will "run fine" for days before it repeats. Some days, it fails multiple times per day.
I suspect it is a PSU failure, just because of how rapidly it reboots. It never even makes it to POST/BIOS. I have no other system to test my parts on. So, I'll have to be purchasing spare components to swap/test, unless I can find out what is wrong exactly, to RMA.
When I use PSU calculators online, they say a 500~550w would be fine. So, I think 850w is fine to also handle all my fans and LEDs.

Note:
The little red LED you can see turning on and off is the power light on my motherboard. I suspect because it is going off, the PSU is not supplying power to my motherboard at those times.
 
Solution
Fixed!(?)

I replaced my PSU with an EVGA Supernova 750 P2. I was hoping that even though my old PSU was "850watt", I'm assuming due to poor quality, it could not supply clean enough power to everything, once my GPU was installed.

The problem has not appeared over the past 48 hours with running the new PSU! :D

Here's my crappy cable management:

THANK YOU TO EVERYONE WHO RESPONDED!!!
The corsair rm series is a pretty low end unit with a heating problem.
So it can be your psu, and just to lighten it up... 200w is alot and gold unit with 850w isnt better than a 520w bronze unit for the task you've given, in fact i know bronze 520w units that are better than your psu.

try to boot in windows safe mode and check your temperatures and voltages.
 


Now that is strange. Usually that would point toward failed motherboard battery - except it makes no sense on 30 days old rig. Plus, it is not coherent with other symptoms. The rest of your description would point toward PSU failure, but it may be something wrong with motherboard too. But PSU is no 1 suspect anyway.

I agree fully. I am already about to purchase a EVGA SuperNOVA 750 P2, 80+ PLATINUM to replace it. I admit, I purchased the PSU only going by Amazon reviews...After having this issue and reading about Corsair PSUs...I am regretting that purchase. That's why I'm pointing my finger at the PSU already! lol While running I'm seeing CPU temps between 45~50c. This case has excessive fans. lol And, my home AC is set at 76F. So, I do not suspect overheating except possibly in the PSU. However, I am unaware of any sensors in my PSU.

Yeah, if there's no temperature issue, I'm banking on the PSU. This is an excellent choice, a Super Flower-made PSU from an extremely modern platform. In truth, the RM series isn't a bad PSU, but the one you're looking at is absolutely top-notch and I believe it has a 10-year warranty (I'm going off the cuff, so I'm not positive on the length).
