PSU causing PC to completely shut down at high usage moments.

[Ekrell]

Hi,


Ever since I got a new CPU: Intel Core i7-7700 my PC crashed when the power usage was high enough.
I've checked the Windows Event Viewer and found the cause: Kernel-Power Error in the category of 47.
I naturally figured out it was because of my old PSU (VS450), so I bought a new one, ASUS TUF Gaming 650W but the issue persists.
Then I tried updating my BIOS in case the CPU wasn't supported in some way, but that didn't fix the issue either.

I was under the impression that 650W can easily handle i7s power usage. What am I missing?
I did try all the usual "automatic windows repair" stuff.

To clarify, it just shuts down completely - then reboots. I can't find anything beyond those logs below. Any assistance would be much appreciated, I'm out of ideas.

You need to tell us your full system specs. Motherboard, GPU and so on. And when you say "crash" does it just shut down or reboot? If so it can also be the motherboard is going bad.

I was under the impression that 650W can easily handle i7s power usage

It can - as long as you don't then overload it with a huge graphics card, several drives, several fans, water cooling and more. So as Frick said, you need to tell us about your hardware. If this is your main computer, you can just fill out your TPU System Specs and reference that.

And when you say "crash" does it just shut down or reboot?

Note he said,

To clarify, it just shuts down completely - then reboots.

@Ekrell - since you have the same results with 2 power supplies, and assuming (for now) that 650W supply is big enough, then most likely the problem is somewhere else. It could be just about anything. Heat is also suspect since you said this happens when the system is tasked. So you need to make sure the interior is clean of heat trapping dust and that you have a good supply of cool air flowing through the case.

When you mounted the new CPU, did you thoroughly clean the cooler of old TIM (thermal interface material) and apply a fresh, new layer?

 

[Ekrell]

Motherboard: H110M PRO-D (Updated: 2018-02-27) [MSI]
GPU: NVIDIA GeForce GTX 1050
The operating system is Windows 10
12 GBs of RAM

I cleaned everything both when I installed the new CPU and when I installed the new PSU. I re-applied a new paste too. I suspected the CPU to be overheating initially, but the general area around it doesn't seem to be hot at all, even seconds after the crash when I checked physically with my hand. Unless that doesn't mean anything.

It reboots whenever the issue occurs.

If there's some way to tell if it's the CPU overheating, I'm open for ideas. I installed a diagnostic programs but I'm unable to get a clear result since I can't predict when the reboot occurs exactly.

@Ekrell You can try limiting the TDP in BIOS, see if that fixes your problem. Since you already replaced the PSU, it may be something on your mobo that went belly-up and doesn't supply enough juice to the CPU anymore.
And like other have said, please fill in your system specs.

 

[dirtyferret]

what was your previous CPU? what is your motherboard & RAM settings? the i7-7700 non-K doesn't draw that much power by itself so what where you doing when "the power usage was high enough"? If it was gaming, what is your GPU?

 

[Ekrell]

My previous CPU was Intel Pentium
The crashes happen most often when I play modern games, the most recent notable one is Helldivers 2.

I updated my specs to whatever extent I could. I'm assuming the casing, mouse, and keyboard are irrelevant.

 

[GerKNG]

why do you think that it is the PSU?

650W is plenty for that system. I still suspect the mobo, see my previous post.

Mouse and keyboard are not important for this problem, but the case is a critical component in any computer system because the case is what defines (and limits) the cooling capabilities of the entire system. So it at least would be good to know your case fan configurations, and your temps.

I think you have an extra "1" in your motherboard model. I am assuming it should be H110M PRO-D.

12GB of RAM is an unusual amount. How is it configure? I assume 1 x 8GB plus 1 x 4GB. Try running with one stick at a time. I would start with the 8GB stick.

I'd start with the usual

• Update BIOS
• Run Windows Memory Diagnostic

I suspect capacitors on motherboard has reached it's end of life, granted that new PSU is not second hand. I had same issue with running R9 290X on Chinese 1000W PSU. So, i have to remove both of them and install old cooler master PSU that was sitting around. My issue was related to PSU. However, i did played games and ran blender renderings on dedicated GPU with full load but never ever witnessed rebooting issue ever again. As per thermal goes my system runs pretty hot as ambient here is around 34 Celsius with humidity ranging from 60% - 90%.
Note, that all components on my system were brand new when i purchased them.

Run Windows Memory Diagnostic

but RAM was fine previously

if it was my PC under theses circumstances, I would agree with @bug and look at the mobo. Maybe try to undervolt the CPU

And they updated the BIOS (missed that on first reading)
