Will PSU latch if OTP is triggered?

[Algebruh]

As title,

 

I am trying to find what component is causing my PC to randomly restart.

Intel I7-10700KF stock - Noctua NH-D15 - A15+A12x25 

Micron Ballistix Sport LT 4133MHz CL17-21-21-40 @1.45v

GIGABYTE AORUS 3090 Xtreme 1905MHz@0.919v/2010MHz@1.063v +900/750 memory clock

Seasonic PX-1000

Lian-Li Lancool II Mesh 

Is this the system you're having issues with?

 

Two things stand out that would cause random restarts. Aggressive overclocks (both GPU and memory) and Seasonic PSUs not playing nicely with high end Ampere GPUs. Remove the overclocks to see if that solves the issue. If removing the overclocks doesn't help do you have another power supply you can test with?

 

Unless the fan is broken or the intake is blocked it's pretty unlikely the PX-1000 would be tripping OTP. Unfortunately I can't answer your title question as I actually don't know if triggering OTP will cause it to latch off. Normally protections like SCP and OCP are handled by a supervisor IC which when triggered will latch off the PSU, but as far as I'm aware the supervisor IC used in the Seasonic PX-1000 (and most PSUs) doesn't support OTP so OTP will be implemented in another way.

Is your PSU latching off (requiring you to switch the power switch off and on again on the PSU) or is the PC just restarting?

Just restarting.

 

These OC settings were fine in the past 8 months, but I will try tuning it down and see what happens.

 

There is a RM750x in my other PC, dunno if the wattage is enough for my current build.

Did you only recently start F@H with those OC settings? It could be that the OC is stable for gaming but not for F@H which is something I've experienced. Also different WUs behave differently and sometimes you'll get a WU that will put a lighter load on the card but cause the GPU clock speeds to boost higher to where they're not stable.

 

You can always give the RM750x a try, but remember you need to swap the power cables. You cannot use the cables from the Seasonic with the Corsair RMx (or vice versa). Only use the cables that PSU came with.

The OC setting I use in F@H is 1860MHz@0.919v +750mem for GPU, RAM setting is the same.

I've been using these settings in the past 6 months.

 

At first, I ran F@H with maximum OC, but it wasn't stable. F@H sometimes showed some errors but never caused PC to restart.

Anyway, I tuned down the OC, and the machine ran fine ever since until recently.

 

I will try swapping the PSU if the problem persists.

If you do still have problems it would be worth dropping the memory OC as well. 4133MHz might not be stable (even if the RAM is rated for those speeds).

 

If you do find the issue is related to the Seasonic PSU you may also have some luck with putting a ferrite choke over the +12V sense wire. See the discussion in this thread:
