a few thoughts:
1 - if someone blows up a power supply and tells 3 people, and they tell 3 people, and they tell 19 people... how many power supplies blew up? how many reports of power supplies blowing up are there? do you see a discrepancy? no? hmm.
2 - if there are 10 times as many corsair cx power supplies as any other power supply, would you expect 10 times as many reports of failure?
3 - if you buy a small power supply and push the living crap out of it and try to get 783 watts from a 430 watt unit and it blows up, whose fault is that?
4 - you get what you pay for. everywhere. all the time. whether we're talking power supplies, diamonds, or hookers-n-blow.
5 - the CX stuff makes great sense at the 430W and 500W level, especially when on sale and/or with a rebate. at the 600W and up power level, their price is too close to other better units.
6 - most "enthusiasts" are more into bragging about stuff than using it, showing off parts that look cool and spending money where it does nothing but stroke their ego. and that's fine. but the CX doesn't cater to them. so they bash it. it's normal.
