A Tier rated PSU on the SPL charts at a great price.
Pros, 1. It's a 1200w 80+ Gold power of course. 2. It has the new ATX 3.1 and PCIE 3.1 standard. 3. It has the new 12v 2x6 connector fir the newest GPUs(especially from Nvidia). 4. Has pretty of connections for most PC components. 5. The fan isn't too loud and it's surprisingly cool(see cons). 6. It has an Eco switch(though I don't use it). 7. This PSU will handle a GPU like an RTX 5090. I'm currently running a RTX 5090 with no issue at the moment(only time will tell). 8. It's a sturdy PSU, yet smaller in size. This made routing the cables so much easier. 9. Lastly the price. For what you get and tge quality this would be extremely hard to beat even if it's competition was running a sale. It's not impossible to beat because some may need some better and/or different where the price isn't justified. Cons, 1. The intake area isn't the most ventilated. I'm actually surprised it stays as cool as it does. Perhaps because I'm not majorly pushing my PC's power limit. 2. The fan could be a little better, but it seems to do the job. 3. I wish some of the cables were braided rather than using flat plastic coated wire. The coated wire maybe easier to route, but I'm skeptical of it's durability and I was cautious when installing this PSU because of this. 4. If your PC is running something like a RTX 5090(especially with a last generation Intel I7s or I9s) I'd advise undervolting your GPU. I will put less risk on your 12v cable, reduce any coil whine and possibly make PSU and other components last longer.

Goat of budget quality PSU's
The goat of budget power supplies. 80+ Gold rating, 850W, modular cables, 0 RPM setting, and 12VHP all for ~$90. Runs perfectly and really I don't have much to say that other people haven't already mentioned. Fan is not aggressive at all, and damn near dead silent with the 0 RPM mode off. Comes with all the cables I'd need. This PSU puts its money where its mouth is. Planning on using it for a commission build as well as some other personal builds I'm thinking about. [Update] I did end up using it for that commission build, turned out amazing, no SATA power cables broke (unlike my EVGA P5), works amazing for a server PSU.

Sold in European amazon without European compatibility.
No type F plug included, why bother selling it in Europe if it does not accommodate the European market standards?

Too damn loud!
Good value, stable voltages, but LOUD under any type of load! Something is either wrong with the fan configuration or maybe with the fan itself, I just know that it is obscenely loud in comparison to the rest of my computer fans, if your GPU starts pulling ANYTHING over 220W, you WILL hear this PSU guaranteed (at least you'll know if it's working or not). I'm gonna keep it because outside of that, it was a pretty good deal, just a shame I have to mod it in order to have a silent PSU
