Computer just switched off at random, for the second time today. This time, it happened simultaneous with a power flux event (the air conditioner halting).

Maybe I need a UPS. :(

Ha ha heehhhh after several days of no problems my computer just shut off at random while I was sitting at it using it, and then less than five minutes later, did it again. Is there a way to get Windows to tell me, after a restart, why the hell it just restarted

Like I understand it might not know why it shuts down but surely if it restarts there's somewhere a record of why

Ah… thanks Windows. Thanks for clearing that up

It's happening now at times it wasn't happening before

I eventually learned to get the data from the "real" event viewer instead of the fisher price baby and this is all it says.

Two references to "Power". I don't know if that means the problem is with the power, or if that's Windows' way of saying "I don't know?".

I did get a core temp log when the computer died last night. The CPU temperature was not high at all at the moment of the reset.

I am terrified of a near future where I spend hundreds of dollars on a UPS, it takes up a bunch of space under my desk, and it turns out not to solve the problem

Every time I buy an Apple computer I eventually have to replace it even though it works and I don't want to replace it, because of planned obsolescence, and every time I buy a non-Apple computer it eventually just breaks

The scariest possible thing that could happen in the next few months is I buy a new mac because Apple forces you to buy a mac to develop for the Vision, then my Windows machine craps out totally and I'm having to use a Macintosh as my daily driver

Okay so everyone has convinced me that probably the problem is my PSU, the computer is power spiking & triggering safeties

My friends who Know Computers say it's important to check review sites like tomshardware or cultist.network & pick a high rated PSU

My current is a ThermalTake GF1 750W gold, the store by me only had a Gigabyte for 850W replacements

Trying to decide whether to buy that, go to Amazon & wait, or contact ThermalTake to replace the old one

In the meantime I'm stuck in Linux

Like the ThermalTake has worked fine for just under two years, nothing obviously changed before the problems started except I swapped my SATA drive for a m.2 one on the motherboard, and that was like a week or two before, then boom problems

So maybe the ThermalTake isn't overloaded, just going bad?

@mcc IIRC Thermaltake doesn't have a great reputation for reliability. So it going bad is certainly a reasonable possibility.

@spinach Reeeeaallly

Would you trust the Gigabyte in the picture?

Review seems to suggest (?) it's a "reliability over performance" pick. I don't even know what "performance" means for a PSU. https://www.tomshardware.com/reviews/gigabyte-ud850gm-power-supply-review

Gigabyte UD850GM Power Supply Review

The Gigabyte UD850GM survived all of our tough tests.

@mcc Likely, "performance" as it is used here means a combination of efficiency, thermals, derating, and noise. Which one is subpar? who knows! Based on the specifics of the teardown in the review, it seems like a good choice.
