[QUOTE="aman.pitbull, post: 1448045, member: 9970"] I've answered almost all of your questions. In my previous post. Still since you require some more explanation : Earthing is usually fine in a PSU, the problem usually lies with your mains. Since you've mentioned you lost a VS4216 which comes without an earthing point, it means that you're getting really low voltages or really high voltages. Hence you need an Automatic-Voltage-Regulator. If you lost your PSU when the switch was in OFF it means that there's something very-very wrong with your house mains(polarities may be reversed). Please get it checked. Get your house mains checked by an electrician. Measure the voltage reading round the clock. Anything above 250V or below 220V suggest that you need to register a complaint with your electricity board. Surges ka jamana gaya bhidu. Nowadays these SUDDEN surges only occur during lightning strikes!!! (at least in Mumbai). The protection you need is most probably over-voltage protection that can only be supplied with an AVR(pure sine for active PFC PSU). "surge Protector is a culprit"!!! Look for burn marks inside and outside the surge protector that may show sign of sparking. Also see if the spike guard's hot when under operation. If not then it's not the culprit. [/QUOTE]
