    lol I won't post up my DXX...it's far worse than any other Ihave seen so far...including components I haven't seen on other PSU's of the same model/make/whatever...soldered by hand on to the back of the pcb's....

    Still use the Galaxy tho.

    Have there been wide-spread reports of failure? CTC are probably not stellar but I have not seen any blown up CTC's either. The occasional one does not count for obvious reasons. Solder gobs on the PCB are nothing new.

    For example see here (page 2)-->
    http://www.overclockers.com/articles1483/

    A minor correction to the article and a few more pictures to put things in perspective): <Sorry for the shameless plug >
    Unit is not built by CWT it is an HEC build. I had a torn up CWT beside it and made the mistake of reading off of the wrong PCB.

    Sony DSC-H2 FTW (looks like this model is the sweet spot for price/performance, beating out the newer models according to dpreview).

    Odds are good enogh that it would xplain the few bad PSU's we've seen. There's nothing that is really common in the death of these Liberty units...some are like plywood's and mine...I probably have a far greater load than he does, and my psu died muc hfaster, so you'd think this was a BOM problem, and nothing but, however the inclusion of the dust covers in the box really highlight dust as a problematic cause for the Liberty line, most likely due to how the air flows in this PSU. you'll actually find a straight draft down between the rectifier heatsinks(smoke tested), and as it would only take a single hair to cause a short, it's more than possible, but as you allude to, very hard to confirm, or deny, as the hair would probably be vaporized when creating a short.

    Anyway, by the burn marks, something is burning, for sure. Without a large number of units to analyze, any summary of events leading to the death of these PSU's cannot be wholely accurate...we need batch numbers, etc etc...


    Anyway, something is killing these psu's, and quite a few of them too.

    It's lack of quality control aka greed.

    I've been using my Liberty 500w for over 2 years now. Hopefully she's not on her last leg.

    Last thing I want is for it to blow when I'm in a dead sleep. I don't think I'd ever recover from that type of trauma. :p

    the worst part when a psu blows up is the time it takes to put in a new one to make sure the the one that blew up didnt take any other hw with it...
    i've once had a crappy cheap psu blow up, never an enermax though, i think your liberty should be safe though as its mostly newer liberties that are crapping out

    How old is it? I wouldn't. Selling your PSU just because of an isolated incident is dumb. It's a good PSU, I guess some are duds

    what else is on your outlet circuit? could some motor in your house like a fridge or heater have kicked on and dropped the line voltage a little? if the voltage drops going into the psu the psu will pull more amps, and a lot of electronics are current sensitive more then they are voltage sensitive.
