I'm lost why my Asus TUF VG279QM is short circuiting and frying. I really need help

[HyperDubb]

The Problem: I tried to connect 2 different brand new ASUS TUF VG279QM to my brand new Gigabyte Eagle Radeon 6600

 

To add some context that may help: 2 Weeks ago from this post going up, I was helping my older brother setup his PC and randomly my house breakers for my room got flipped off (I assume it was because all the light in my room were on and we had 2 PC that used quite a bit of power made it flip). We didn't really think about turning off all the power extension bricks and flipped the breakers which blew up and fry my past Sceptre 30" widescreen and the GPU I was using at the time which was an ASUS OEM 1060 6GB card, His PC was fine luckily. I assumed those were the only thing that got damaged, after a few days I got a VG279QM and a Gigabyte Eagle Radeon 6600 with a new Rosewill SMG 750 off Newegg. As soon as I connect the monitor to the GPU with DP, It fried the DP port on the monitor but everything else was fine. The day after, I bought a Pre-built to use but it's not here yet. On May 18th, 2022, I got a replacement VG279QM as I thought it would be fine to plug it in but this time it fried the power port on the monitor, I'm going to get a refund if possible. Hopefully when I get the pre-built there wouldn't be any problems. ALSO, forgot to say but my old Samsung monitor could connect to the GPU and work perfectly fine and I plug the VG279QM into another socket that on the other side of my room unlike where my PC and everything else is connect to.

 

Problems that I suspect could lead to the monitor ports frying: 

• Possible power surge damaged the fuse box? I'm not a electrician as I'm just a 17 year old kid but I think this could be possibility.
• Damaged Motherboard? I'm not really sure if this would be a problem but I had this thought ever since the first VG279QM broke.
• Damaged GPU? The GPU works fine but it destroyed 3 other monitors that are new but my 10-12 old Samsung monitor is fine.
• Damaged Surge Protected Power brick? I'm not sure if this normal since it Surge Protected, I use a brand called CyberPower.

Some Solutions I've thought about or have done:

• I thought it would be my motherboard and GPU be damaged, So instead of getting new parts. I bought a prebuilt that is an upgrade compared to what I use to have.
• I thought of getting a new Surge protected power brick that is trusted and highly rated to replace what I have, I've never heard of CyberPower power brick other than the CyberPowerPC. (If anyone could recommend me any good Power Surge power/extension bricks that I could buy from a Canadian site, That would be greatly appreciated.)
• Possibly move to another room in my house?
• I was think about getting a Power Socket tester but I'm not sure if it will come in any help as I'm not really sure how to tell what's good and bad.

What will I do for now?: For now, I guess I will try to focus on refunding the monitor and GPU, PSU bundle back to Newegg. Hopefully I get the pre-built in once piece and nothing is or will be broken and I get some solutions and recommendations.

 

My current PC specs but without the monitor

The Pre-Built I bought (I'm going to replace the AIO to a Corsair iCUE H150i Elite Capellix and the RAM to what I have right now)

 

Please ask me anything that will help you and I will try to respond as fast as possible unless I feel like I'm being attacked.

Another thing you haven't accounted for is the DP cable you are using. Some cables include an extra power line that should not be connected, I believe this is an older spec for the cable and is no longer used, but it may explain why modern monitor ports fry but the older monitor is fine.

User burning down the components shouldn't be RMA acceptable. That's cheating the seller(s) or the repair shops, even the manufacturers.

 

Get an electrician and have him check the sockets, the lines and everything. You might be having voltage on the grounding.

If you suspect faulty power strips and surge protectors, replace them without further consideration.

I used the DP cable they sent, I would assume it should be compatible with the monitor. Thanks for the info though.

I understand that it isn't RMA acceptable but I did contact them about it and they told me just to send it in. I am still at fault though. I will see if I could get an electrician in to check but I really think it could be my motherboard as other tech stuff I have connected to the sockets didn't have any problems. Thanks you for recommending me some solutions though.
