Professionals can be mistaken too, I have worked with a lot of hardware and man have I been wrong before. You can check the wattage on the back of the pc where the power cable goes in, just to make sure.
But yea more ppl are reporting crashes, I used to crash a lot too but bought a new PSU which fixed my problem. (note I'm still crashing, but no bsod or hard pc crashes. Just software crashes)
Hopefully it will be fixed sooner rather then later, you can check you systems reliability viewer and check on the hard shutdowns, it could give insight into what is causing the crash (example kernel power 41 is something with power draw or PSU)
