Is my PSU causing random shutdowns?

Hello everyone,

About a month or two ago, I upgraded my PSU and my GPU. Since then, the system works fine except for one problem. It will randomly shut down immediately without warning (black screen then turns off). Strangely enough, the PC doesn't shut down under heavy load. Just yesterday, It cashed while playing Mount and Blade: Warband, which is more than capable of running on my PC. However, a few weeks before, It crashed while simply idle or editing a document. :??:

The system has (surprisingly), never crashed while playing intensive games such as Battlefield 3 and 4 or Far Cry 3.The crashes are really random, and have no warning such as fps drops or any error. I have already tried to disable restart on system failure, but there are no logs or errors to be seen when I start it up again. :heink:

However, when I look through Windows Event Manager, I see around 19 critical error logs with the tag being Kernel-Power. Most of the errors are exactly the same, except for a few that have a different powerbutton timestamp value (most are 0), and one log has a BootAppStatus of "3221226513". I will attach screenshots of the errors in case they will help.

My PSU is powerful enough IMO and according to most PSU calulators (which give me ~350W minimum, which is way off IMO :pfff:). Instead, my GPU (XFX 7870 GHz DD) says 500W minimum. I have a 550W PSU, so I have no idea if its faulty or is its a problem with my house's power. In case you need them, my specs are:

-1-- NZXT HALE82-N 550W PSU (Non- Modular)
-1-- ASRock B75-DGS Motherboard
-1-- i7 3770 CPU
-1-- XFX R7870 GHz DD Edition
-1-- Toshiba 1TB HDD
-1-- DVD Multi drive
-1-- USB/memory card reader
-2-- 4GB (DDR3?) RAM sticks (8GB total)
-4-- Fans (120mm?) (1 intake, 2 exhaust, 1 heatsink/cpu fan)


I'd appreciate your help! Thank you!

Do you have a UPS you can buy to test your house power? Because if plugged in a UPS and your computer doesn't turn off, then its definitely your house power. Most UPS, such as most cyberpower ones, come with software and USB cable for monitoring purposes if the power does blip. Or if thats not an option, plug something else into the same outlet that will be very obvious if your power blips (phone charger, a clock where you can take out the internal battery, etc)
 


Thanks for the reply, the problem is, these shutdowns are not frequent at all, as you can see in the screenshots, around 20 crashes within 2 years, most of which occurred in 2013/14. I do not have a UPS but if I were to plug in another device into the outlet, there would be a slim chance that there would actually be a power blip IF it were the house's power, because of the low frequency of the crashes.
