[SOLVED] my pc keeps restarting randomly

[tarif.tarif735]

My pc keeps restarting on it's own.I dont use UPS so basically it can't protect my pc components maybe.But my house doesn't have any High voltage spike problems.
Can it damage my motherboard or power supply or maybe ram or cpu?
What gets usually damaged to to power surges?

My pc specs
Ram - 8gb
Gpu - gtx 1050ti
Cpu -core i5-7500
Powersupply - Thermaltake 550watt

Most likely it's the PSU latching off. Should replace it.
