We had to urgently buy a pair of these power supplies to replace in one of our old production servers that failed. They arrived quickly and are working well so far. The fit was exact, and the systems ran off the new PSU without error or warnings. Worked as advertised for Dell Poweredge 1950 replacement psus and didn't even have to shut the server off when installing these power modules as the server is hot swap-able. Good buy.
