Desktop Switching Off Randomly

[Kanishka-5]

Recently I assembled a new desktop, below are the components I have used

CPU:- Intel Core i5 3330
Motherboard:- Asus H61M-D
RAM:- G.Skill Ripjaws X 8GB @ 1600Mhz
GPU:- Sapphire Nitro RX 460 (4GB Edition)
PSU:- Thermaltake Smart 500W Continous Power Supply
Case:- Thermaltake Versa H15
HDD:- 1 X Seagate Barracuda 1.5TB HDD
1 X Western Digital 320GB HDD
SSD:- Silicon Power 120GB SSD
Other Components:- 4 X Arctic F12 PWM Fans
NZXT Sentry 3 Fan Controller

Now the issue with this build was that the first day I built it, it works fine but then after switching it off the second day and switching it on the morning it booted up and then switched off (NO BSOFD appeared) It did this 3 times and then successfully booted up. And then this kept happening for 2-3 days and then One day it just didn't boot all the way to windows so I removed my desktop from the current location and then took it somewhere and did a Fresh Install of windows (cause I thought my Windows OS was corrupted). After that I faced no issue after moving it back to its original place, but then again at Night when I was Playing Black Desert Online It just randomly switched off and then booted up again and then the same issue as before was persisting (The one where it keeps turning on and off with no BSOFD). So my issue is that is there a problem with my power outlet or is there something wrong with my Power Supply Unit cause I can't really think of anything else that may be causing an issue.

I would love to get details on what the issue might be

Hi if you can still boot the pc download hwmonitor and check temperatures of your cpu and gpu since you could be throttling.
IF gpu is below 80 - 90c then its fine and if cpu is below 70 then its good

Just checked the temps and my CPU is around 40 - 45, GPU is around 45 - 50

These are on idle, I'll check them while gaming

So I Just checked the temps while gaming and benchmarked as well, CPU is around 45-50 and GPU is around 55 to 60, occasionally goes above 60. And while benchmarking the computer just switched off 2 times.

Okay so I had thought it was an issue with the PSU, so I replaced it with an EVGA 500W 80+ Bronze Model, but it still kept giving me the same issues as before and therefore I looked further into it and found out that the issue was being caused by my Memory running at 1600Mhz, Originally it was running at 1333Mhz and it should be able to run it at 1600Mhz cause the CPU and the Motherboard and RAM all support it, But I guess due to some limitations of my motherboard it didn't want to co-operate. So I ran it at 1333Mhz and the issue was fixed
