Can I ask what is probably a daft question but one I just don't seem to be able to find an easy answer to. What are the standards in PC Power Supply Units?
I have had a couple of PC's that have had failed PSU's, the checking of which I'm quite happy with, but I really struggle to find compatible PSU's. For example I have a Mesh PC and the PSU is a HEC-300, put that into Google and you get only two pages and no indication of any other type of PSU being compatible. Obviously there are the different connectors but the same connector can have different wiring and different voltages / ampages, aagh!
I'd be grateful of any advice or to be directed to somewhere where you can find out more. Many thanks.
