I got my new system as with Asus GTX 1080Ti Strix, i7 7700K, Asus Strix Z270E, 4 x Gskill Trident Z 16GB... These are all brand new, but my PSU is from my previous PC ( Thermaltake Toughpower 850W ) which I bought in 2014.

I am using Windows 10 Pro as completely updated.

The problem is occuring on games only... I am playing with 4K mostly.
When I try to play any games on the PC, ( ingame videos and on some significant points of MafiaIII and Batman Arkham Knight, opening intro on Assasin's Creed Unity etc... ) rebooting without any blue screen etc... But for example, never happened on Forza Horizon 3 and Outlast 2...
Also no problem on Windows & internet usage...

PSU has direct 2 x 8 pin red PCIe cables which from inside the box ( so not from any plugs over it ) to GPU.

What let me do? PSU calculation websites are all saying my whole system's needed wattage is 560W... Just Z270E & i7 7700K both needing 340W on load.
Isn't my PSU not enough to operate my PC?

I have 1 SSD, 4 SATA HDD, 1 SD Card Reader, 3 big fans in the Case ( Thermaltake Level 10 )

 
Solution
In most cases, it's either your PSU is faulty and no longer supplying enough power. Or your CPU could be overheating. Have you monitored temperatures during high intensity games?

I am very sensitive about GPU because of my previously bad experiences.
So I tested it when I purchase from the store with a "less configured" system... About 2 hours with 3D Mark's benchmarks. Result was successful.

Yes, with your recommendation I got a screenshot during Mafia III. Resolution is 4K. Also, I am using a Hyper 212X cooler on CPU. But it is almost 70C on highest settings of the game... What is your opinion, normal or not? It is after 2 hours different games and finally on Mafia III.

+ I also Deactivated High Definition Audio and Activated nVidia's High Definition Audio.
+ Power option has changed to Performance mode.

Results :
Assasin's Creed Unity is passing easily from the definitive rebooting point on intro. Now the game is playable indeed.
But now rebooting randomly. :??:

Mafia III has not rebooted yet but I am still afraiding...

Apologies for not responding to your last post Thermo...must've missed it.

Regardless, based on your response I would've recommended swapping the PSU, so I'm glad you've done that, and it's all sorted! And thank you for best answer. Happy gaming sir!
