Computer all of a sudden began crashing

[D3monw3st]

Hello everyone, 

Today's a very sad and frustrating day for me. My recently new-built PC has started to crash rapidly and suddenly. This issue has only begun to occur a few days ago, and I've had the PC for less than a month. 

Components: https://pcpartpicker.com/user/D3monw3st/saved/3rkTBm

What happens? When i'm usually gaming for only about an hour or so, the computer would be working fine up until the screen goes black and peripherals lose LED power; however, what's interesting is how the components like GPU still have the LEDs on. 

I've tried stress testing the computer, but only for a few minutes. From that, it seems like the issue only arrises whenever i'm gaming or under high load.

Any help would be very much appreciated. 

Thank you!

Had a similar issue with my system when i first built it, a windows re installation fixed it.

Okay, something I did forget to note is that there is a loose connection between the mobo's PSU connector and the PSU. The cable is very tentative in giving power, so it could be a mobo issue or PSU. Basically, if the cable isn't going in at a certain angle it won't give power.

So push the connector in?
