Is my PSU dead/degraded?

[GENICODE]

I have been having power problems recently, every time i boot up a more demanding game my pc resets after about 10 minutes. Ive been monitoring % Power values on MSI Afterburner and even in lower end games it keeps spiking to 90% even though on paper it should be able to provide mor then enough power

Specs:
Intel i5-4460 3.2 GHz
Geforce GTX 1060 Zotac Mini 6GB
CM B600 PSU

PSU Tier list tier 1-2 are good for gaming

I would recommend an EVGA SuperNova Gold G2 / or new G3 /GS / GQ, Platinum P2 / PS, or Titanium T2 or a Seasonic M12-II Evo or S12-II

GOOD PSU EVGA is a B2, G2, G3, P2, GS, PS, or T2. Avoid the EVGA B1 and G1 series/ I bought a EVGA G3 with 7year garentee
