This old FSP350-60PN psu at just 350 watt has been powering my test server for years and still lives. It has proven capable of keeping my Intel Xeon X3220 stable with up to 15 Harddrives and their controllers hooked on, even on full load. Stripping it the box for a complete cleanup and overhaul now and probably replace the psu so it can retire with it’s pride intact.
