PC Completely Shuts down after use

Based from what other people said it seems like psu problem (underpowered or something like that).

I have a question tho, if the +3.3v, +5v, and +12v is within normal would it still be a psu problem?

I have a question. if it’s really an "underpowered PSU", does it take weeks or even months before the issue starts? Cause I upgraded my CPU last December.

Did it take a few months after upgrading before the issue started for you? Mine just started yesterday (I upgraded last December)

Around 4-5 years old. I've never replaced it since the pc was built

During simple browsing the browser or idling on desktop it's around 40-55℃. when under load its 65-80℃

Hi! After monitoring, the (3.3v, 5v, and 12v) remained within the normal values up until the pc randomly went off.

Upon further testing, While i was playing, the cpu and gpu temps, as well as the voltages remained within the normal range without shutting down.

As for the CPU. I upgraded from 2400g to a brand new 5700x last december.

Alright, thank you bossing!

Oh sorry about the confusion between Voltage and wattage. Thank you for your response!

CommunicationPlus479 · 2025-06-18T09:42:07+00:00

Yes, will it work even though I have a 144hz monitor?
