(This also counts for focus based PSUs like Antec Earthwatts and Asus Strix, with the exception of the nzxt-e and the new Focus GM, GX, PX and SGX lines (it meets 2.52 atx, which require hardware changes))

The Seasonic Focus line has been suffering major criticism on the PSU subforum lately. Why?

Old revisions (2017-2018) will shut off on some GPUs (970, 1080 ti, vega 64, Vega VII, 2080 ti). it'll will trigger the overcurrent protection, and will shut down immediately. This is likely due to the high transients the GPUs are known to put out

New revisions (2018-2019) have a bigger headroom, but aren't built for it and start to ripple at the loads where the PSU would shut down at with the older revision.

If you plan on buying one, either wait for the v2, or choose a different PSUs, for this you can check the PSU tier list, or ask around on the forum.

With that is focus known to be quite loud under load, has a staggering 200% opp on the 3.3v rail, but this isn't as concerning as the above mentioned problems.

edit: the 2019 based Focus GX/GM/PX have fixed mentioned issues
