Default Re: What is a CSN60?

C16, which I'd removed before I took the photo, is in front of the heatsink on which T6 & T7 are mounted, and hidden by it. The circuit to which you kindly provided the link is indeed similar, C7 being the equivalent component there. As I noted in one of my posts the original 2uf capacitor only read about 5nf on one of those cheap Chinese testers, so I'll fit a new one, and check electrolytics, etc. Interestingly, the manufacturer's name is 'Foshan Hanyi Computer Device Co.Ltd.' so the PSU is, as you say akin to an ATX one. I suspect you're right about the 3rd transformer being the standby power, driven , or swirtched, by the CS1N60 mosfet. There is indeed provision for a wire link to allow for voltage doubling operation on 110-120v, as you say
