Question while playing games in high graphics my pc crashes?

[blynk]

recently i upgraded from an i5-9400f to an i7-11700F and when playing a game (lets use fortnite) at high graphics, my pc will just simply shut off, then reboot like ive just turned it on. i was wondering, (stupid question incoming) if my 550w power supply is the problem?

GPU: GALAX GeForce GTX 1660
CPU: Intel i7-11700F
RAM: 16GB DDR4 2666 MHZ

if it matters

Replace the PSU. If that doesn't help, full reinstall of Windows.

You had to replace the motherboard so you should also reinstall Windows.
