I know this will not be popular but I'm sure we have all gone PSU crazy, I have built a few hundred PC's over last few years and 95% of them had cheapie PSU's, the other 5% were so called top brands. I've had a handful of failures and believe it or not most of them have come from the 5% top brands. None of the failures caused other components to fail, so I'm sure that PSU's taking out Mobo's are well over stated. You must also bear in mind that most branded machines are fitted with cheap PSU's.

I know I'll get slated but I'm speaking from personal experience and I can't do no more than that. So for me it's horses for courses and if a cheap PSU fits the bill then I'll use it.
