Kernel Power (41) Error

[Anthroxx]

Hello guys, 
I bought my PC a month back i had a faulty PSU at first (Cooler Master 550MWE) but the retailer changed it and gave me another one (GameMax 650) since then unexpected shutdown is happening at least once a day. I ran prime95, haven benchmark no error came. I also changed my power cable and also monitored my temp while playing games which was normal at below 60. Should i change my PSU or anything in my system is not compatible with each other.  Any help would be nice. Thank you.

Run memtest86 to make sure it's not a memory problem 

Also that psu ( from what I can see) is not necessarily an upgrade, it's subpart

Did my memtest result came in with 0 errors. Should i try to change my PSU ?

Seems likely it could be the PSU, that "GameMax" unit is placed in the D Tier on the PSU Tier List. I'd consider swapping it out regardless of if it's the root of your issues because you're not running a 'cheap' system. I'd recommend a Corsair RMx (2018) they're usually pretty easy to find, are highly rated (One of the best in A Tier) and aren't too terribly expensive although it's not the best time to be PSU shopping... Otherwise try to get a B+ unit that's highlighted gold!

Anecdotally, I had Kernel Power 41 errors with my old PSU which was a high end Seasonic Platinum unit (7 years old and was replaced under warranty!) Swapped it out with an EVGA unit and it was resolved, might be just as simple for you.
