Old PSU died. Ordered a new one, worked great for 3 days, now computer will not turn on.

So about a couple of months ago, I thought my Corsair power supply was failing. I’ve had it for about 8 years so it makes sense that it was finally on its way out. Whenever I would press the power button on my case, the fans would start spinning but my PC wouldn’t start up. I could work around this by holding down the power button until the fans turned off, and when I would turn on my PC again it start up fine.

Eventually this would not work anymore. My PC would not turn on at all. So I decided to by a new power supply, an EVGA BQ 600.

I took pictures of how everything was plugged in, unplugged my old Corsair PSU, and swapped in my new EVGA one. It worked flawlessly, for about 3 days. I was playing a game and then it just completely shut off.

Now, when I try to start my PC, the fans spin barely a half turn. I unplugged all of the PSU cords, and plugged them back in. I sprayed the inside with compressed air and also all the dust filters, but it will still do the same thing.

Did I just buy a fault PSU or is it another one of my parts failing?

Any advice is greatly appreciated.

Here is my current parts list and pictures of the inside:
