Alyx draws more power than probably any other game that you play, and your logs indicate a hardware problem. Playing Alyx will push your system to limits it wont even reach using stress testing hardware (As stress testing is usually only CPU or GPU, while alyx makes full use of both). So if you have a hardware issue, Alyx is going to highlight it. Not only does it cause high power draw, from it's excellent use of resources, this draw is also sustained (especially the GPU, but also the CPU).
As you probably know, a set time until a hardware crash strongly points to a temperature related crash. Alyx will test the limits of your thermal solutions. The first thing to check is your GPU while you play, as GPU is often pegged at or around the max power draw of your GPU due to Automatic SS. GPU-Z will allow your to log your temp data as you play, so if you crash you can restart and see the final readings.
I'm going to assume that you use that CPU in workstation tasks, with it 100% pegged, so I assume that you know that it's stable without overheating.
Now, I know that's a beefy PSU with a high capacity. And a platinum rating, nice. You wont be surpassing that capacity, as you know, but that model came out quite a long time ago. Have you been using it for a long time? Even great PSU's reach their end of life. As a PSU heats up it gets less stable, and if you're using a PSU that's reaching the end of it's life then that will only make the issue worse. As Alyx pushes hard against your PSU, and it heats up, it could be delivering unstable power causing your restart - the first signs of a dying PSU.

If you are still skeptical that it's hardware, which is understandable, you can easily put it to the test. Add this to your games launch options via the games properties in your steam library:
-console -vconsole +vr_fidelity_level_auto 0
This will disable the auto resolution scaling, as having it on causes your GPU to constantly draw power like never before. If it's a PSU or GPU issue, disabling this auto resolution scaling should stop your crashing. Just make certain that your resolution scaling is set manual and 1.0 in steams settings to ensure that you are rendering the game in your headsets native resolution. (Edit: Of course you can increase from 1.0 after you see the game is stable, just don't go too high).
You just need to disable the auto SS that the game uses, it will take tremendous pressure off your GPU. Without doing that, the game ignores your usual SS settings and runs your GPU at max to improve image quality through hiking the SS way up - After you have disabled it, with the above launch options, if you change the SS manually make sure that you restart the game. SS changes only take effect if they are in place when the game launches.
Edit: the launch options again:
-console -vconsole +vr_fidelity_level_auto 0
Additionally make sure that your manual SS settings in steam settings are sensible and don't cause too much heat.
Thank you very much Bilbo for your detailed response, and providing a possible solution. To answer your question regarding how long I had the PSU, I had purchased all the computer components (including the PSU) April of 2018 and assembled early June of 2018 (So about 2 years). As you may already know the PSU should be good up to 5 years give or take. Regardless, I hope your solution remedies the problem. Im wondering if I should just return the game if its going to be a continuous problem or wait to see if future updates for the game will solve the issue?
In all likelihood it's just highlighted an existing issue in your system that would be best to identify. It will be a continuous problem with the game, unfortunately. At least until you can identify what is going wrong with your system.
Return the game if you don't want to, or can't, find the issue with your system that is causing the restarts. Otherwise figure out what's up, fix it, and enjoy the game.
One thing: Are you certain that ALL of your GPU's power cables are connected? Many GPU's don't require that, and only have the a second optional socket for overclocking and extreme draw - however, Alyx requires that your GPU is fully powered. So, if they aren't all plugged in (firmly) then that is most likely your problem (though it does still look like it's temperature related, so it would be surprising if this was your problem).
I wont throw in the towel yet and dig into the issue further. I was planning to clean the computer anyways so ill double check the wires and make the suggested adjustment through the steam library. Thank you again for setting time aside to help me out its much appreciated.
Thank you Tea, I'll do that as well. I currently have a cooler master cosmos c700p (case), which id hope would eliminate heat build up especially with 7 fans. Im looking into liquid cooling, but was hoping to do that maybe when I upgrade to 64g of ram and a 2080ti at a later date. How im seeing it if the suggested fixes do not solve my problem then i'll have to expedite my plans or return the game.
If heat turns out not to be the issue, it can still be quite a fair bit. Driver issues, failing hardware and overclocking to name a couple.
You can eliminate driver issues by ensuring your drivers are up to date, along with testing older versions.
You can eliminate overclocking issues by disabling overclocks. CPU doesn't appear to be overclocked, though. Can't say given the information provided about your GPU and RAM.
The best way to determine if it's failing hardware is to try other parts, or try the parts in another compatible PC. But, if it's not heat issues, driver issues or overclocking issues, you've probably got a failing part.
If it turns out to be heat issues and the PC is clean, check your airflow setup, fan settings and ensure the PC is able to breathe. Don't forget you can always underclock to reduce heat. You'll probably find you can get away with lower voltages than what you're currently running without losing any performance. Keeping a side off the case can also help with heat issues. You may need to clean and apply new thermal paste.

Your CPU likely got to such a high temperature that to protect itself from damage it completely shut down your computer. You'll definitely want to fix that problem because getting that high of a temperature, especially on a CPU is not good.
