Where are you located, what is your preferred site for purchase and what is your budget for your PSU purchase? Also, make and model of your case? I'm asking of the latter since sig space specs can and will change over time, so this thread and any suggestions will go moot to the person in he same boat as you're in now.

Power Supply prices still SUX and I see nothing to say they will change anytime soon.
This would be a very good choice or the 850 watt model for 15 bucks more if you plan on upgrading.

I am in the US, my preferred site for purchase is Amazon, make and model of the case is GAMDIAS APOLLO E2 ELITE ATX Mid Tower Case (sorry for the caps, I am on mobile and it would take forever to retype it.)

If your in the US it's about the best deal you will find. SuperFlower is a very well brand and makes PSU's for many brands.
You might be surprised at the few companies that actually make power supplies (about 5 that are decent)

If it's mot a A then it should be.

It looks like it is B-tier, not the absolute best of the best, but a huge improvement over my current F-tier psu

Pretty much you have.
Seasonic, SuperFlower, CWT, Andyson, FSP. Then a bunch of no name cheap crap.
Of course most of these will make a PSU to the customers specks so some are better than others.

People like NZXT, Corsair, MSI, ASUS, and a ton of others have never made a power supply as far as I know of.

According to who?
Made with quality parts and a 10 year warranty. You can get down to nitpicking anything made.

EDIT if you look at some peoples so called A.B.C.D list I could debate a bunch of it You could buy one from list C and it last just as long as a 3X the price A list. People way overthink things although with some of the newer cards having huge power spikes some of the top brands tier list PSU's just cant handle then unless you buy way over the watts needed on paper.

Look up my Seasonic G series that is 8 years old where is it?
Had 0 problems and it's in it's 2nd build.

People overthink things like this way to much.

Their a big difference in junk and decent.

EDIT you can buy the best of the best and it fail or you can buy just decent and it last many many years just the way electronics work

All companies have their ups and downs. EVGA has the execrable W1/N1, Corsair has the old VS and CX before JonnyGuru worked for them, SeaSonic has some very cheap PSUs they outsource, Super Flower has a few very mediocre basic PSUs at low wattages available in Asia only, and so on.

Though of the well-known brands, companies like EVGA and Corsair generally have deeper portfolios of quality PSUs than Thermaltake and Cooler Master, who have sold a lot of junk over the years. With those two, you pretty much have to get one of their best 20% or so of releases. But in the end, you're not a buying a random PSU from a brand, you're buying an individual, specific PSU, which may be good or bad.

I just wish that good quality PSUs had RGB instead of fire hazard quality PSUs having RGB to try to hide the fact that they are bad quality.

RGB for enthusiast PSUs hasn't really taken off because by and large, PSUs are in locations that aren't going to be displayed. And enthusiast cases are simply becoming better and better at completely hiding PSUs from the world. For example, in the Lian Li 011 Dynamic XL I use, the PSU is basically tucked away on the right side of the case and completely invisible to a viewer and a *lot* of people have used that case and its variants.

I do think it would be nice to see the PSU or at the very least the specs of said psu in the case. For example my old hp workstation had the psu specs on the side of the psu. It would be nice (if maybe unnecessary) to have something similar (maybe the specs on the side of the psu and a window so that you could see that side of the psu and nothing else.) on modern cases. What do you think about that?

It doesn't really appeal to me personally, it's just a rectangular box with safety components. I don't particularly care about having RGB brakes on my car or and RGB gas cutoff valve in my furnace, if such things exist (I guess the former might, I doubt the last one does). I'm not the Emperor of PC Building, of course, since everyone's feelings might vary.

Not that I'm against RGB of course. My main rig, if I have the lights running, can be seen through my basement office window from the street, and if I'm working in the press box at a baseball game and need the more powerful laptop for something, my Alienware laptop is usually the only source of RGB in the press box.

I thought that too so when I wanted to replace my PSU way back in the summer of 2015 I bought a fairly expensive Seasonic 660W platinum unit. At that time the GPU I was using was a lowly 1050 ti but I was planning on replacing it within a year or so.

About 8 months later I got hold of a Vega 56 to replace it with and all was well for a while. Then I started having problems while playing Grim Dawn. The system would shutdown at a particular point in the game every single time I got there.

After doing various troubleshooting stuff to discover why this was occurring I found that if I used MSI Afterburner to reduce the power limit to my GPU to 80% the shutdowns stopped happening. This pointed to my 8-month-old expensive Seasonic PSU being the cause. Which it was, which really pissed me off. It was down to transient power spikes caused by the GPU tripping the over-current protection of the PSU and causing the shutdown. So the moral of this story is even the supposedly best PSU brand is not immune from issues with their products.

After that, I replaced the PSU and went a bit overboard with a 1KW Platinum unit from Corsair.

The worst part is you probably couldn’t have gotten a refund because the psu itself was working perfectly fine.

(Assuming a psu doesn’t fail prematurely) how long do high quality PSUs last? I know some have 10 year warranty’s but I am not sure how long they actually last.

Who knows? But if the warranty is 10 years then there's a good chance it will last 10 years.
I replaced a friends PSU which he had been using for a long time, he was running a sandy bridge i3 so it must have been at least 10 or 11 years old, I think it was a Corsair TX PSU if I remember correctly. It hadn't failed I just thought I better replace it before it did. Actually, I don't think it was a TX it was some model of Corsair PSU though.

Yeah, my dad has a Lenovo SFF workstation with an i5 2400. The PSU still works just fine almost 13 years later.

It *might* be. Like the consequences would be hidden for a long time if you ate a pound of bacon every morning for breakfast, internal damage can be caused *long* before it causes anything visible such as parts failing or sudden power off.
