Is that the 350W Flex/1U PSU listed in the OP? If that's the case, then recycle that piece of garbage and get a proper quality PSU. Even if that CPU was to cause major transient power spikes, there should be no way whatsoever for it to cause shutdowns on a 350W PSU, or cause the system to not POST. While current generation GPUs do see major transient power spikes far above their rated power limits, CPUs do not, at least not to any kind of comparable degree. Did you ever test the build with a different PSU?I suspect that my power supply is inadequate for the i5 12600K 125W TDP and will be switching to the 65W lower TDP processor:
Maybe I will be sacrificing 10% or so single core performance and maybe 35% multi core. But I don't use the extra power anyway. Both have (UHD Graphics 770) which is what I seek for this APU build.
- Intel Core i5 12500 65W TDP
Intel Core i5 12600K 125W TDP
I don't know how good advice that is - while there are absolutely people far too gung-ho about PSU quality about there, the problem with a bad PSU is that it can kill literally every component in your PC if it goes bang. And while the PSU space isn't the wild west of 15+ years ago, there are still a lot of what JonnyGuru used to call gutless wonders out there, especially from no-name brands, with wildly overblown specs.I've been using this PSU for a couple years now, no issues. Don't let people talk you out of going for "cheaper" parts. Some people have crazy anxiety about not having the "best", mainstream stuff. Good on you for not being like that. Following.
The first flex I got from aliexpress was a dud. It happens. Get your money back and try a different one.
He’s right, make sure you get what’s right for your system. I did, and it has worked great for me.I don't know how good advice that is - while there are absolutely people far too gung-ho about PSU quality about there, the problem with a bad PSU is that it can kill literally every component in your PC if it goes bang.

I don't know the specs of your build, but I'd be wary of using that PSU you linked simply due to it being dual rail, delivering 11A on each 12V rail - that's just 132W per rail, and just ~260W total on 12V, rather than the 350W promised (given that PCs in recent years leave 5V and 3.3V to USB and m.2 and essentially nothing else). That's enough for a reasonable CPU and GPU, sure, but care needs to be taken to not common the rails (which won't kill the PSU, but can cause weird behaviour leading to instability or the PSU dying prematurely), and to not push either rail too hard.
Sounds to me like your build is sufficiently low power and you happened upon a decent quality unit - but that doesn't mean that everyone will be that lucky.
Those used server Deltas are good PSUs, the problem is that many of them are used-up good PSUs, with very little life left in some of their components. And it's impossible to tell which is which. If refurbished well, they can be fantastic though.Okay, I took my new (questionable) Delta PSU and connected the PSU to my previous Build, this one linked below. My heart sank when it didn't power up. But I had forgotten to plug in the wall power on the empty case. After that, it works fine. I processed this image, and am replying to you on the (questionable) Delta PSU just like in this image. I am also leery of Ali Express Flex PSUs. But I believe these used Delta PSU are high quality PSUs pull from servers. Though, I could be wrong.
