A quality PSU has extra protection circuits in it. A PC built to cost will have a very cheap and very nasty PSU in it that tends to cause damage as it fails. Compare the weight of your PSUs and you will notice the difference.gimp_hunter said:The mobo was defo broken as well because my PSU didn't work at all...cheapo parts from the manufacturer as my PC has survived a number of lightening/power cuts....or perhaps the manufacturer has a kill switch, after warranty has expired, everything breaks![]()
