I just dissected a Zippy / emacs (model R2W-6500) for another project I'm working on, there's quite a few KMG's in it. It's probably circa 2010 (it was running a 5400 series Xeon system). It's a high-time PSU, its a redundant server supply, working fine. Most the ones in the secondary are KZE and KY. The reason for the dissection was I'm repuropsing it for something less demanding and wanted to quiet the fans down. They're 8500RPM feeding off the +12v rail. Much quieter feeding from the +5v instead!
