Needing some concurrence

[eidairman1]

Looking for some concurrence here. AM4 rig (Not mine, but my lady's) has been running good since around Christmas 2021/early 2022. Last week it started randomly shutting off suddenly. I put HWINFO64 on to check volts and temps. Nothing is standing out on any of the volt rails (3.3, 5, 12), idle temp is 35-40C.

The rig is used for email, solitaire, business, aka general use. (Built for Longevity, came from a P4 Dell)

I checked the volts coming out of the wall psu cord itself and it is 122VAC so normal (I have a multimeter)

Specs:
Zalman Z1 Neo Case- 3 Fans
Seasonic Focus/Focus Plus GX-650
AsRock Steel Legend B550
AMD Ryzen 5800 (Same as 5700X)
Thermalright ARO-M14G
ThermalGrizzly Kryonaut
Crucial Ballistix Gaming 3600 32GB
XFX Ghost R7 250X
Crucial MX500 256 SATA SSD
Pioneer BDXL Burner
Rosewill "Gaming" MX Brown Keyboard
Logitech Tracball
NEC 21" DP Monitor.

Now here is the kicker, it never shut off on me yesterday, but today it did earlier for my gf, the weather has been somewhat rainy but she says she didn't have any sudden flickers or lights shut off. It is on a Surge Master, which is pretty old.

It was stormy last week as well.

So I'm wondering if the psu's ovp/ocp might be kicking in detecting a power source anamoly or is a little sensitive.

I will have to research the mobo manual to see if it has ovp/ocp like some Asus X99 motherboards had and it was causing the users problems.

I am thinking about getting a new power strip and possibly running a 3 prong extension cord in to get the rig off of the circuit in the office.

Any other ideas?

I'm thinking about picking up a spare psu that is the same line as to test without having to pull the cables out of the case (Cable Routing)

Based on what you've said, I'd have to say at this point it could be the Surge Master showing it's age, causing the PSU to trip.

I'd try a different/new one just to see if that stops it.

Probably will be the cheapest option outside grabbing a new PSU

Glancing at product page PSU does not support NLO (No Load Operation).
System is very low power draw.
Suggestion:

In BIOS, find a setting called something like "Power Supply Idle Control". GB AM4 boards give Low Current Idle and Typical Current Idle.
Try Typical Current Idle and see if crashes continue.

I will look and see if there is anything like that.

I Will also look at exact model of PSU too, just dont remember the 1 I put in then.

It's just a sudden power off, not the typical freeze or bsod associated with a crash.

I bought a Prime GX750 for my rig originally, it was during the shortage in 2020 and was pretty much all I could get..

It works great in my other system with 5600X and GTX980 Classified.. but in my 5900X/3070Ti setup it will crash so hard I have to flip the switch. But my EVGA 750 shit box has no problems..

The issue has stopped, its possible the outside plant was causing issues, this was pretty close to a storm even
