PC randomly resets

[Zhyder]

So I’m pretty new to PC’a so I don’t know if this is common or something but here it goes. For about 2 weeks now my PC has been resetting with no warning at random times. Sometimes it would crash in the middle of  it starting up, or sometimes it would crash after a couple of hours. I thought it was an airflow or heating issue so I cleaned my fans, replugged them and it was still crashing. After that I tried to see if it was maybe my CPU or GPU so I tried bench marking it with different games which did not solve anything. If anyone has any idea I’d appreciate it! Here’s a list of my parts: Zotac GeForce 2060 6GB, intel core i59600k processor 9th gen, Cooler Master Hyper 212, Gigabyte Z390 UD Gaming Motherboard, Corsair Vengeance LPX 16gb DDR4 RAM 3000, EVGA 600 BR 80+ Bronze Power Supply, ADATA SU800 12GB SSS, Seagate BarraCuda 1tb Hard Drive, Corsair Carbide SPEC-06 RGB ATX Computer Case.

Sounds like a possible defect in the power supply, or perhaps an issue with power delivery from the wall itself.
