Question My PC reboots after 1-2 minutes after going into a Video Game

Hello,

Whenever I play any game (CSGO, Overwatch, anything with any graphical demands) my computer quietly shuts off after around a minute or so into the game, then reboots. My computer rig is brand new and I have recently installed some enhancements, it was working fine before I did the enhancements. I will list what I got initially, enhancements I made, and some checks I have been doing to gleam information on what is wrong.

Here is what the rig came with:

ibuypower Gaming Desktop Trace 054i Intel Core i9 9th Gen 9900k 3.6 Ghz
Motherboard: z390 Phantom Gaming 4-IB (Motherboard manual link below)
16gb DDR4 1 (2666 MHZ)
TB HDD 240 GB SSD
NVIDIA GeForce RTX 2080Ti
Windows 10 Home 64 bit
650w PCU - Channel Well Technology, Model Number GPS650S

What I upgraded:
  1. 650w PCU into 1000w PCU, Seasonic Prime Titanium ACCTRU100AW
  2. The ram into CORSAIR - Vengeance RGB PRO 32GB (2PK 16GB) 3.2GHz PC4-25600 DDR4
  3. Added 3 fans to the top of my case, HD120 RGB, they have their colors going but they are not spinning because they are not plugged into the motherboard (I don't know where the inputs are for these damn fans).

What I've checked:
  1. I initially suspect that this is a graphics issue, as when I look at my task manager charts that display system usage the crash seems to come after high periods of 3D percentage usage on the GPU panel. The GPU seems to spike up to 100% quite easily and I don't know why.
  2. My graphics driver is updated to the latest version. I tried to go to earlier versions but that did not solve the issue.
  3. I tried going back to 8GB of RAM and that was not the issue, I checked to see if my comp was registering my 32GB ram and it said it was.
  4. I checked the cords around my new power supply (came with its own cables, had to redo the wiring for everything) and made sure all the power cords coming into and coming out of the PSU were fit snug into their proper positions.

Thank you so much for the help!

Added 3 fans to the top of my case, HD120 RGB, they have their colors going but they are not spinning because they are not plugged into the motherboard (I don't know where the inputs are for these damn fans).

A simple peak into your manual for the motherboard will tell you where ALL the fan headers are. Look at the manual on page 7. After you locate page 7, goto page 8 and read numbers 2,3,16,17. Looks like yours fan headers are 4 pins connectors, if your fan's only have a 3-pin it will still plug into that same spot, just 1 pin wont be used. That 1 pin is for smart fan speed

  • 1 x CPU Fan Connector (4-pin)***
  • 3 x Chassis/Water Pump Fan Connectors (4-pin) (Smart Fan Speed Control)****
***The CPU Fan Connector supports the CPU fan of maximum 1A (12W) fan power.

****The Chassis/Water Pump Fan supports the water cooler fan of maximum 2A (24W) fan power.
CHA_FAN1/WP, CHA_FAN2/WP and CHA_FAN3/WP can auto detect if 3-pin or 4-pin fan is in use.

2 at the bottom, 1 below the CPU and 1 at the top of the motherboard. Heres a picture for reference:
