It's not just Anandtech. All reviewers have nothing but praise for Seasonic. They have the best reputation in the industry at the moment and all their PSUs have a 10 year warranty to back it up.

Jonnyguru's last Seasonic review: https://www.jonnyguru.com/blog/2018/07/03/seasonic-prime-ult...

Literally nothing in the bad & mediocre summary sections, and with nothing but recommendations for the entire series:

> Our look at the PRIME Ultra Titanium series has now at last come to a conclusion. We can now definitively say there’s not a bad performer in the bunch, and while all do have some very minor drawbacks I can’t see any reason not to recommend any of them.

They actually have 12 year warranty at least for the PRIME TX ones.
