Question PSU Causing Boot Loop In 1 Machine, Not Another?

TLDR: Can a PSU cause a boot loop in one machine but not another?

Built a machine in the winter. Here are the components

I have had issues with boot looping. I reseated CPU, tested ram, replaced mobo.
Finally, I swapped the Corsair CX750 PSU with the Corsair HX750 in my work computer. That seemed to solve the issue. I had it checked out by Microcenter and they said they did not see any issues, everything looked good.
However I've since identified an issue. When running high graphic games like The Witcher 3 or HellBlade:Senua's Sacrifice the machine will reset. No issues when playing less intense games like OctoPath Traveller or Ori and the blind forest.

I built this PC with the geforce 2080 to play all my games, not just the less graphic intense ones.

So that is the situation. With the HX750 the machine works but wont let me play graphic intense games. With the CX750 it boot loops as soon as it enters windows, weird because the CX750 causes no issues in my work machine, and the HX750 works fine in the gaming machine until I try to play graphic intense games.

So - can a PSU cause a boot loop in one machine but not another? Does it sound like this is a PSU issue or something else? Help!

If anything overclocked? Sounds like a power supply issue, you did not list the specs of your work machine, but going to guess it uses less power than your system with a 2080 card.

Thanks hang-the-9 for quick reply. Nothing is overclocked. The work machine is running a gpu and mobo that are 3 years old. I plugged the specs into https://www.coolermaster.com/power-supply-calculator/ and i shouldnt need more than 750, which is what has me stumped. Also stumping me is that i checked over everything, and had microcenter check everything too. They said it all checked out and that its a software issue that the games are causing a reboot. but i dont believe that to be the case, both because thats unlikely multiple games would cause a reboot and also because the swapping of the PSU causes reboots immediately upon entering windows.
