The prime is a bit more expensive. What is the difference between the two and which is better? Thanks!
I've seen professional reviews of the Focus Plus Golds which show them to be excellent units. I believe they are slightly more recent as well. The Primes are considered flagship units and have a longer warranty, but I haven't seen as many detailed reviews of the Prime Golds.
There’s actually quite a few reviews out there.
Both of those are the Prime Titanium, not Prime Gold. Built to a different spec, I wouldn't use those to assume anything about the Prime Golds.
(That said, Seasonic has proven to be quite solid lately, but until I see specifically a detailed review of a Prime Gold, I'm hesitant.)
1kw and 850w version is very solid.
