For use with WHAT? Truthfully, no, they are not very good. Specs SEEM ok at first glance, with 50a on the 12v rail for an "actual" 600w unit, but it's only rated for 30°C and has only a 3 year warranty whereas any halfway decent unit these days would be rated for 40°C and a really excellent one might be rated for 50°C, and still maintain it's ratings as well as not go out of spec on ripple and voltage regulation. Not to mention, a half decent unit would also likely have at least a five year warranty with very good units these days having 7, 10 or even 12 year warranties.
You could probably do worse than that BR unit, especially right now with current conditions, but you could for sure do a whole lot better by spending a bit more.
