Well, the Ultra XVS 600w that I got for a fraction of it's retail price (around 60% discounted) failed sometime over Christmas. I'm not quite sure when, since I was away, but my computer stopped sending work units to the FAH servers on the 29th of December. So, I get back to my apartment yesterday, and I notice all the lights are off... This is strange, since I've got three dedicated 15a circuits in my place... 1 for my computer stuff, 1 for my fish tank/setup and 1 for my kitchen/lighting. All the lights in my small apartment are attached to the 120v kitchen line. So, when this PSU failed, it shorted out, and kicked the breakers for ALL three of my circuits. This seemed odd, and I immediately assumed there was a power surge or something, that just happened to kill the PSU. Well, every other piece of equipment in my place is fine, my UPS is fine, and not a single lightbulb has burnt out. I live in a huge condo apartment, and nobody else on my floor experienced any outages or problems. Oh yeah, and the PSU won't start up at all. Not even with a paperclip, outside of the case. I ordered a Corsair 620HX, and I'll be taking apart the ultra shortly . Anyone ever heard about this sort of a failure? I'm still not convinced that it was the PSU that died, but an external power surge happened to take it out... But it was behind my UPS... Hmmm... Looks like the insulation failed in the main power transformer, arced and flamed up.
