Resolved Question

Power supply voltage

Hey recently been having issues with pc turning off during games so I was searching to try and find something similar and found that the 12v power going to the cpu could be my issue. I monitored it yesterday and it wasn’t hitting the 12v mark I believe 11.9 was highest and lowest being 11.808.

Is this strictly just a power supply problem? I originally thought it was the motherboard but if that’s not to blame and it’s the psu it will make my life a lot easier. It’s not the cpu overheating either i haven’t seen it go past 58c and everything is at there base clocks. Cheers

Actually that's close enough.
https://www.google.com/search?q=12+volt+tolerance+psu+pc&gl=US finds the usual +/- 5% tolerance so 11.808 is fine. I've seen this out by 10% and no issues.

I worry about the dual +12V rail ( https://www.amazon.com/Thermaltake-TOUGHPOWER-Modular-Supply-PS-TPD-0750MPCGUS-1/dp/B00IUQRPQS ) but there is a single rail and even with a dual rail unless there's a dozen HDDs I think this gets a pass.

BE SURE the BIOS is current and google that model motherboard like this:
https://www.google.com/search?q=Asus+crosshair+vii+hero+x470+shuts+off&gl=US

Seems like this board has a lot of complaints about random shut offs. See if anyone has fixed it.

Thanks for the help

It was the motherboard causing the trouble ended up just swapping it out and putting my old b350 board in now everything works as it should. For some reason they said some apps conflict with the asus apps and cause the shutdowns I deleted every app and still same problem so had enough after that and gave up on it. Didn’t think spending that much on a board could turn into such headache... my first asus part and that’ll be my last after that

Just so you know.

I've fielded other x470 board questions and something seems off on those regardless of the maker.

Keep an eye on PCMR and the boards they use for Ryzens at https://www.reddit.com/r/PCMasterRace/wiki/builds (Spoiler, they are listing x450 boards right now.)

Okay will do

I’ll place the x470 back into my other pc I’m building (needs ram and psu still) see if I can get it working but will stick with b350 board till next ryzen’s comes out in my main pc. Don’t see the point in getting new board now unless my b350 isn’t up to the task (which it seems like it is atm ??)
