Recent PC activates briefly before powering down after a short duration
It wasn't anything extreme, probably just a League of Legends problem. I haven’t had to worry about overclocking since I saw the shutdown issue. I’ll test the PSU in the old machine.
If the situation were more extreme with record high FPS values, you'd likely need to replace parts entirely and a fresh power supply would be a solid starting point. I wouldn't rely on it even if it functioned in your previous system. You'll require a working unit to determine if the PSU absorbed anything (though I'm still uncertain if it's the PSU itself) and hopefully everything else is intact. The advice from @--SID-- is solid, and I support the supernova and corsair models, plus adding seasonic for extra assurance.
The PSU didn't function properly with the older system either. It might have been a mistake on my part—I acted quickly. I'm glad we're beginning here, and I don't want to come back to this thread again next week. Thanks to both of you!
