Top power supply, unnecessary words about the Prime series from Seasonic. I have had it for 2 years now, it has run a 3070, a 7900XT, and a 5800X3D, all comfortably.

The main reason I bought it, instead of, for example, an RM850x from Corsair, is that its cables DO NOT have capacitors. As a result, the cables are much more flexible compared to Corsair, etc.

Seasonic Prime GX 1000W
Power supply with high-quality construction
Many and high-quality cables
12 years warranty

Power supply with very high-quality construction, much heavier than other power supplies at these wattage levels. I was amazed when I opened the package, saying wow, what a tool this is!! Many high-quality cables that are convenient for cable management (the 3X8 Pin cables needed for the graphics card pass through the top of the card, and the 3 cables pass through the channel in the box for SATA and the 12 Pin for the motherboard comfortably), giving the feeling that you get what you pay for here. I was careful where I held it so as not to leave any fingerprints. It was purchased to be able to support the graphics card mentioned below, as well as provide stability and low temperatures in the system it was installed in, due to the very stable voltages that, according to the company's claims and various tests, are at very high levels. It operates with the fan kicking in when it reaches and exceeds 50% of the consumption (temperature) it can handle. Finally, judging by its construction, the 12-year warranty, and what I have read, I hope it is reliable and good for many years.

Seasonic Prime GX 850W Full Modular 80 Plus Gold

In a PC with CPU: 5600x, M/B: MSI B550 Tomahawk, VGA: RX5700, RAM: 16GB, 2 Nvme of 1Tbit, 2 SSDs, 1 HD 1Tbit, NZXT liquid cooling, and with a Cooler Master GX650 PSU for over five years, the PSU suddenly started causing issues with my PC. When I was playing a game, the screen would suddenly turn off and I had to do a hard reset. After restarting the PC, I didn't have any drivers, they were missing. At first, I thought it was an issue with the AMD drivers. After trying different versions of drivers and not resolving the issue, I concluded that the problem was with the PSU. Since I didn't have another PSU available to test, I decided to purchase a new one. I searched for various reviews on the internet and ended up choosing this specific one. I bought it immediately and when it arrived, I was impressed by its quality, weight, and the numerous cables it had to connect peripherals. The connection and installation were easy, as expected for this type of PSU with detachable cables.

Now, with the PC running, everything works perfectly and the problem has been solved (fortunately). Additionally, the PSU is completely silent since it is slightly oversized for the power consumption of my PC. Now someone might ask, why did I choose such a large one instead of a smaller one to save some money? The answer is because it has a 12-year warranty and you never know what power requirements future PC manufacturers will have.

P.S. A piece of advice for friends who want to build a new PC from scratch, in my opinion, the first thing someone should buy is a very good case where everything will be installed, and it should be GOOD to VERY GOOD. The second thing is the PSU that will give life to the PC. The rest depends on each person's preferences.
