Question Superposition Benchmark freezes PC - Is it the PSU or a bum GPU?

Salutations!

I recently upgraded my GPU in my 5 year old System from a GTX 760 to a new GTX 1660 Ti.
As I usually do with a new GPU I ran a few benchmarks on it.

Unigine Heaven provided me with a, in my opinion, weirdly low score for a new 1660 Ti so I tried the Superposition Benchmark.

The first time I ran it on 1080p Extreme it ran without jitters on a steady 25 FPS, however something bugged and it kept looping without displaying the results.
As soon as I pressed a button, my PC Crashed to a BSOD with the CLOCK_WATCHDOG_TIMEOUT error.

The second and third time I tried running it it froze my pc, while the audio kept playing.

All Superposition tests gave me 98% GPU Usage.

My first thought was that maybe I got a faulty GPU, but I read around online and in many cases people stated it could be an old PSU aswell.
Now I have a 5 and a half year old Corsair CX500M in my PC.

What do you think is more probable? If it was a faulty GPU, wouldn't other GPU heavy tasks also suffer? I can for instance play BF1 on Ultra with no stutters at all, but I have heard that the CXM series is supposed to be pretty crappy... (tho I have never run into issues up until now...)

Here's some more System Info for the big picture:

CPU
: Intel Core i7-4790K at Standard Clock, slightly undervolted
GPU: Gigabyte NVIDIA GTX 1660 Ti 6GB
RAM: 16GB (4x4GB) of G.Skill RipjawsX DDR3 RAM
PSU: Corsair CX500M
MB: Gigabyte Z97X-UD3H-CF
OS: Windows 10 Pro 64-Bit

One thing that might point to the PSU as the culprit is that I am running quite a few peripherals (besides the obvious Keyboard and Mouse, also an Audio Interface, Webcam, 2 MIDI Keyboards), so maybe the power consumption is a bit higher than calculated?

Thanks in advance for any insights!

Cleaned old Nvidia drivers with DDU already?

Does it help to do a clear cmos? Do this with the pc of the power, so cable out of the wallsocket.

Can't hurt to upgrade that psu since only having a 3 year warranty, also newer gpu's have afaik the possibility that they can ask for power in spikes which this psu because of the way it's build might not like.
