I have an ongoing problem with my new build shutting down randomly. It is very sporadic: it can be 5 times a day, or once in 5 days.
My temperatures are fine, I have tested the wall sockets and have the latest (Asus BIOS). After shutting down, the reboot/shutdown cycle loops until I manually power off. On reboot, there is no anti-surge warning.
Recently, I unplugged 2 120mm fans, 2 sticks of RAM and an SSD. It has not happened since. I am wondering if my power supply is insufficient (although it is an AX860i from Corsair). Is that possible, particularly if the Titan is drawing a lot of power?!
Spec:
Intel i7 5820
EVGA Titan X Hybrid
8 x 8GB DDR4 RAM (Corsair Vengeance)
6 x 120mm fans
Noctua D15 cooler
4 x Samsung EVO SSDs
Corsair AX860i PSU
Sabretooth X99 mobo
By 'shutting down' I just mean the power suddenly cuts off, as if I had turned off the wall socket, there is no normal shutdown procedure.
I am using Ubuntu, where is the events log please? Thanks.
The incident happened again today. Instead of turning it off during the reboot cycle, I left it to resolve. I then got the error message from Asus saying that it was due to the Asus anti-surge protection because power surges had been detected.
I am extremely reluctant to turn the anti-surge protection off, in case my components are damaged by a genuine power surge. Is there any alternative?
Thanks for all the responses. I replaced my PSU with a EVGA SuperNOVA 1200 P2 and have had no problems since. So, either the Corsair 860W PSU was insufficient or it was faulty.

SHORT ANSWER:
Change your PSU to more than 1000 watts. (1200w/1500w)
Explanation:
Even if you didn't mention your PSU Watts, I'm sure your problem is a PSU shortage watt. As you have:
Doing the math with adding an additional 250 watts to the results as a safety room for your computer, you would end up needing more than 1000 Watts for the current built.
When you pick the PSU, you have to see how much watts you need from the hardware requirements, and then add between 100 to 300 additional watts (depends on your usage), which will cover any shortage that you may experience in the future from usage or adding new components or overclock. Plus, some external connected devices are also counted in. Any device you connected to the computer that DOES NOT have a dedicated power supplier will use PSU power, which means more watts will be used.
So, again, your computer needs more watts to be consumed, but your PSU couldn't offer them. That's why when you unplugged 2 120mm fans, 2 sticks of RAM and an SSD, the computer went back to normal because you free some watts from being consumed.
