Summary: I've owned my custom built PC for about 8 months now using this power-supply, but I heard very bad reviews about it failing in the night and catching fire and taking some of the systems parts with it. I plan on replacing the power-supply for that, but it hasn't malfunctioned in the 8 months I've had it(but I turn my pc off at night when I'm not using it).
Summary: It works extremely well. It's very quiet and staggeringly cooler than most power supplies I've had in this computer. Including one that offer less maximum wattage. I have a single gripe, and it's the 6pin connectors are not clearly labeled to identify what rail they're on. This was an issue when I had a video card that only used one 6pin as I wanted to split the load across the rails and couldn't tell which one was which.
Summary: I've used only Antec power supplys for years. The reason is simple they aren't expensive but they are of high quality. I've seen many a generic power supply fail but keep conducting power. That usually ends up in costly damage of a system. Antec power supplies are designed to fail and self destruct if something goes sidways. I deally any power supply should only die of old age and usage.
