Question My PC suddenly turns off, temps are fine

[fikri.pratama829]

My PC turns off for no apparent reason, this happens on both gaming tasks and idle. Sometimes it happens shortly after I turned on my PC and sometimes it happens after like 18 minutes since logon. I'm suspecting the issue comes from either the mobo or PSU but I'm not really sure. I built this since Oct 2018 which means 6 months of usage

My specs are:
Ryzen 5 2600
AsRock B450 Pro4
V-Gen Tsunami 3200mhz cl16 2x8gb ram
Zotac Geforce GTX1060 6GB Amp
Samsung 860 Evo SSD 250GB
Seagate Barracuda 2TB HDD
Windows 10 64-bit
Bitfenix Whisper M 550W

This is the screenshot of my Hwinfo and UEFI if it helps

Usually a power related issue.

I think so, maybe my PSU was dying? I need to be sure before disassembling my rig and RMAing suspected component

Just my opinion , but these type of unpredictable shutdowns usually are a PSU issue.

Same thing happening bought on November 2018:
Cpu - Ryzen 2600
Mobo - Msi B450 Tomahawk
Ram - 16gb 2x8gb Corsair Vengeance Rgb pro 3000
Gpu - Gigabyte G1 Gaming GTX1080
PSU - Seasonic M12II 620 Evo

Can't seem to understand or figure out what is really going bad ?

Did you manage to figure it out or correct it ?

Clean the dust out of your case. This may be a reason why.

Dust cleaning doesn't really lead to computer shutting down instantly, it has to be a power supply related issue.
Put in mind that a vega graphic card is a power hungry card, and you never know your power supply might be starting to fail.

Donno about OP's condition, but I have taken the components out so many times in this past 2weeks, resetting refitting rechecking every single things that there are not even a particle of dust either side of case fans blades.
