I just got one of these. It looked pretty decent to me, since it has dual rails at 19A and 20A respectively. I've seen a lot of people all over the web that say that they work great, and some that have replaced them just because the fact that they don't cost a lot scares them, but I've yet to see a post that they suck. I think they don't cost as much because HEC makes them themselves.
It's not the most attractive or quiet PSU, but if it gets the job done, I can forgive it for being ugly and loud since it's cheap 🙂.
