Weird stuff happening to PC

So I bought this system over a year ago, it had a Pentium G4400, GTX 750ti, 8GB DDR3, ASROCK H110M DGS DDR3 MOTHERBOARD, 120GB SSD AVF POWER SUPPLY WITH 550WATT 20+4PIN, my case is this: https://www.tecware.co/f3 and is connected to a BENQ MONITOR 19.5" DL2020.

The problem here is that randomly while I play games, my PC would lose connection to the monitor (monitor says no signal) but I still hear the sound that is being outputted from my PC (e.g. music, people talking on discord, etc.). When this problem occurs, I would hear my PC's fans become really loud, very loud.

Over the past year, I've upgraded my system. I've added a hard drive first, the problem doesn't start to happen, everything's fine. Next I upgraded to a GTX 1060 6GB mini by Zotac. The problem starts to occur. I thought it would be a bottlenecking problem so I saved up for an i5 7600. The problem still persists.

I'm thinking that it's the PSU that's causing this problem as I'm not using a 6-pin power connector that is from the PSU but I'm using a molex to 6-pin power connector converter as a 6-pin power connector for my GPU as my PSU doesn't have one so I resort to a temporary solution. So far the only games that causes this is only Overwatch.

My GPU temperatures would be on a constant 80 degrees celsius and my CPU would be in between 70-80 degrees celsius. Can someone confirm this?

If it is a PSU problem, would my whole system explode one day due to the molex to 6-pin power connector converter?

If the answer is also yes, what PSU should I get? I'm on a budget as I'm merely a high-school kid that saves up money to upgrade his PC he built. My results are near too but I don't want to burden my parents too much just to upgrade my PC

Here's a video demonstrating the problem I'm facing with: https://www.youtube.com/watch?v=EkAqoT_wpRE

What is the cause of the problem?

That's a standard micro ATX case and it should be able to handle any full size ATX PSU you can get. Most of the time when you add new hardware onto an old-ish system, the PSU can't handle the new hardware. and that is where the shut downs will happen. While we can't pinpoint the system without it being in our presence, the reason why we speculate that it's the PSU that is causing the problems is because most of the time it is. And it's not the wattage of the PSU, it's the quality of the contruction of the PSU. So a poor quality 550W may handle a new card, but will not run at full capacity. Whereas a...

Nah it wouldn't explode necessarily. You're more likely to cause a short first before a full on explosion. Don't get me wrong the shorts can be just as dangerous. But it is always good to be prepared with a much better PSU. Here's a good one that I recommend that isn't too expensive:

So the problem is caused by my PSU?

Also my case is this: https://www.tecware.co/f3

does that affect what kind of PSU I can get?

Whereas a high quality 550W unit will handle the new hardware without problems.
