The "drive remaining life" value is usually determined by the number of writes, e.g. in comparison to TBW, so I'm not sure why yours is off by that much. However, drives can and usually do survive well past 0% on that metric, sometimes ten times over. Which is why I was looking at the spare block metric instead - you haven't used any spare blocks yet, when you see that change is when you should be more concerned.
 
Long-term I have to believe those high temperatures are bad for the drive. Just not sure what you can do about it since you care about aesthetics.

Good news and bad news. The good news: it doesn't look like it's damaged in any way. You still have 100% space blocks (64 in hex). Percentage/lifespan used is 35 (53 in decimal) which is where HWInfo is getting 47% (100 - 53 = 47) from, which is not normal. However the data units written matches up - 15411309x512B (sector size) = 7348GB. So I'm not sure why it's reporting that way, although CDI is ignoring it.
 
The bad news: 64C idle is rather bad. This is the temperature of the controller and it will throttle over 70C. With regards to the flash: NAND likes it hot when programming, however heat during data retention/reading will be detrimental (although, it will be reflected by more writes generally). I suspect temperature is the real culprit here.

7TB is not a lot at all, per month basis it's more than my 250gb one but still,  it's little compared to what the drive is rated for, as someone else said it's probably just the software used that is bugged.  

Looks like either the reporting is buggy, or you managed to buy the one SSD with the shortest life ever made.
 
It says you have 7.27TBW, and the datasheet rates it at 320TBW.
So according to the datasheet you're at 97.73% life left. 
 
So they likely botched their firmware reporting.

If you say this then there is no AMD CPU that is better at gaming performance than the 9700K. You're probably already well aware of that. Buying into the Z390 platform right now isn't very advisable, because that's a dead platform and the next generation of Intel processors from what I've seen is going to be on a whole new platform, so if you really say future proofing is most important to you, then I would strongly advise against buying into that platform.
 
AM4 on the other hand is very flexible and gives you a lot of options, and from what I've seen is supposed to be supported until Ryzen 4000 series (2020?) so you get more future-proofing with AM4 than you do with Intel at the moment. But AMD's side of a CPU that's priced similarly to the 9700K is the 3700X or 3800X and you counter those options with the fact that 9700K gives better performance, so it kind of does seem like you already have your eyes set on going for Intel anyway.
 
But regardless, for motherboard options, iirc Gigabyte makes some pretty good Z390 boards, like the Designare and the Aorus Master. From what I've heard ASUS kinda flopped their Z390 lineup, not too sure about MSI and ASRock.
 
For AM4, all B450 boards dont get as expensive as the high end Z390 boards do, so you're probably looking at X570. If onboard audio matters do you (even though most people would just recommend you get a seperate DAC or pcie sound card) , just look for anything with the Realtek ALC 1220 codec - which is the highest end on-board audio solution at the moment or equivalent (Supreme FX1220 i think is what ASUS calls their version of the ALC 1220) but most of the X570 motherboards above the 250USD price range have this audio codec already.
 
I don't see much point in getting anything that's above 300 USD, unless you're a real power user or there's a specific feature that you want, but something like the X570 Aorus Master, Strix X570-E, ASRock X570 Taichi, MSI X570 ACE is kind of as high end as I would personally go for a motherboard. If you don't mind losing out on RGB Bling, the MSI X570 Unify is a great deal and is cheaper than any of the boards I've mentioned, as it's literally an X570 ACE that has one less LAN port, which shouldn't matter unless you have a NAS or something.
 
All the X570 boards I've mentioned are pretty much all top-tier boards already, I don't see the point in going for anything higher like the X570 Godlike or X570 Extreme unless you just have way too much money to blow. But if that's something you're interested in, the boards basically just get better as you go up the price. Most X570 boards starting from the 200 USD price point are already pretty good. for the cheaper recommendations I'd look at the X570 Aorus Elite or X570 TUF-PLUS but if i remember correctly one of both of these boards do not have the Realtek ALC 1220 codec and have some sort of compromise, whereas the ones I mentioned in the last paragraph are your kind of no-compromise boards.

I've tried both, but to no avail  
 
I have my PC on top of my desk, pretty sure that wasn't an issue.
 
That's exactly what I thought, but it turns out that wasn't the issue.
 
Went to a PC Parts retailer yesterday, showed them the issue I was having and they thought it was a PSU issue as well. They pulled out a Corsair RM1000x PSU to try with my PC and the same thing still happened. We were all pretty surprised. Tried pulling out my 2070 super, plugged in a GT 710 to see if it was because the GPU was pulling too much power but this didn't fix it as well. Next was a reformat on my OS drive (even though I told them i'd already reformatted my OS drive 2 or 3 times before going there and it fixed nothing at all) but I guess it would give them the assurance that it's not a driver related issue so I agreed anyway. Issue not solved. They pulled a brand new model of the exact same SSD, installed windows on it and it was still happening. It was either the CPU or motherboard at this point (both of which I bought from this retailer) but it was already near closing time so I left my PC with them overnight.
 
Today, They popped in a brand new Ryzen 5 3600, left it running for about 4 hours and it did not restart at all. Also ran a few Cinebench runs to make sure everything was okay. Picked it up a few hours ago and it's been working fine so far. Got a 1 to 1 exchange on the CPU and that's it. I must have been pretty unlucky to get a faulty CPU, but the fact that issues only started coming up 2 weeks after the old one has been in use instead of showing issues on the day of installation is pretty weird to me. 
 
 
Thank you guys for your replies, but it appears my issues have been solved now  Just thought I'd write this down to maybe help anyone who's going through or will be going through this in the future and stumbles upon this thread.

This is very informative and easy to understand, thanks a lot for this explanation! It's more than what I was expecting to get from a reply. 

USB is just a pathway for devices to connect to the CPU/ram/storage. You can think of it as an alternate to PCIe or ethernet - it's just 1's and 0's getting moved between the thinking chips of a computer and a peripheral device. If your audio control panel says "Dolby DSP sound card" then yes, there is in fact the equivalent of a soundcard between the USB port and drivers of your headphones. It's very small, and possibly more limited than traditional soundcards, but the microchips inside do the same jobs.
 
Digital to Analog Conversion (DAC) will take the binary from the USB and synthesize an analog signal (often represented as a sine wave) to put through a small amplifier chip (likely integrated into the same silicon as the DAC), which then goes through your headphone drivers. The drivers actually perform another conversion - this time from electrical energy to sound energy! Any device that performs energy conversion is called a transducer. Microphones are also transducers. Your microphone audio follows the same path as your headphone audio, but in reverse. Sound -> transducer -> analog electrical -> Analog to Digital Conversion (ADC) -> binary over USB.
 
USB speakers will work similarly too. That is to say, there is a DAC inside the speaker connected to your computer via USB, and the DAC feeds a small amplifier (also hidden inside the speaker) which in turn powers the drivers/woofers to produce sound waves.
 
 
Hope this wall of text was something along the lines of what you were looking for. 

The only time motherboard audio comes into play is for 3.5mm input/outputs. Everything else is digital. 

tier D, for the Ryzen 7.
 
Ultra gaming and Gaming 5 has terrible memory OC, as they struggle to do more than 3466MHz

PBO is a kind of overclocking, so not even that
 
Around 80C? I've seen it run a 2700X at stock and get above 100C
 
From 6 core to 8 core
 
Asus should let you overclock memory better, but since they want you to buy X470 and X570 don't expect it to go further than XMP settings

Right, GPU shouldn't be the issue.
 
DP1.2 is limited to 4K @ 60Hz as far as I can tell. DP1.4 can do 4K @ 120 Hz (not 144Hz) without compression (Display Stream Compression, DSC). It can do more, but that requires additional support for DSC, both from the monitor and the GPU.
 
In regards to cables, here's a very good explanation:
