When you upgrade your existing PC and go for an ultra-powerful high-end RTX 5080, you also need a good and reliable power supply. For my system, this one is a huge overkill (I was looking for a 1000W but couldn't find one available). SEASONIC is considered one of the top, if not the best, companies in power supplies, in terms of reliability and performance, and I decided not to spare any expense for the safety of my system. (You know how electricity is in Greece, especially during bad weather). This particular one has a 12-year warranty.

Personal advice to everyone: DO NOT buy a low-quality power supply just because you are on a specific budget and need to cut costs somewhere. Cut costs elsewhere, but don't spare a single euro when buying a good power supply, pay even more if needed.

If anyone is interested, my specs are as follows:
- MOBO: MSI MPG B550 GAMING PLUS
- CPU: RYZEN 7 3800X
- RAM: G.SKILL TRIDENT DDR4 3600MHZ 48GB 4XDIMMS
- GPU: MSI RTX 5080 SHADOW 16GB 3X OC
- AIO: LIAN LI GALAHAND 2 LCD 360 BLACK (SIDE)
- PC CASE: LIAN LI O11 VISION COMPACT BLACK
- LIAN LI FANS WIRED x3 (DOWN) + WIRELESS REVERSE x2 (EXHAUST)
- PSU: SEASONIC PRIME 1300W TITANIUM
- STORAGE: 1xSSD nV.Me SN580X 1TB 1xGIGABYTE SSD 500GB 1xHDD WD 1TB

(BEFORE YOU SAY ANYTHING, I PREFERRED, INSTEAD OF SPENDING CRAZY MONEY TO GO FOR A BETTER SYSTEM WITH DDR5 RAM ETC., TO GET A BETTER GRAPHICS CARD AND I WOULD SUGGEST THE SAME TO YOU IF YOU WANT TO UPGRADE)

Well! Having been burned in the past in the search for a power supply (since I was unlucky enough to have one burn out on me, episodically), with the help of Cybenetics, who thoroughly test them (previously we had SPCR filling this gap), I ended up with this power supply.
For those who are not familiar with the brand, I encourage them to do a little research on who makes the most reliable power supplies. I emphasize "makes" because Seasonic is a manufacturer, while Corsair, for example, provides the design and has them made to their specifications.

It may be overkill for my system, which will never demand 1600 watts, but firstly, this power supply has excellent performance efficiency (reaching up to 94% from around 250 watts, roughly, and continues up to almost 1600), secondly, because my system doesn't draw even 1000 watts, it operates without even turning on its fan (since I have the hybrid mode button pressed and it only turns on when it reaches a certain temperature), and thirdly, even if I add a second 4080 super in the future, I will still be comfortable.

The cables it provides appear to be braided, but it is a technique engraved, let's say, on the cable casing. It comes with zip ties and "combs" to make the cables go where you want them exactly as you want. It also includes a 90-degree angle for the 24-pin motherboard connector.

Note: the only power supply I found to be 1% more efficient than this one, roughly, was the Corsair AX1600i, but it is not ATX 3.0 and it costs more.

That's all from me.
