KDMPOWER KDM-RDCL300 ATX Power Supply for HP MediaSmart Server EX470 EX475 EX480 EX485 EX487 EX490 EX495

No information included with the PS, not even a pinout. Time to grab my multimeter. Not recommended for the inexperienced types.

Bought one of these a few months ago through another online channel. Power supply worked for a few months, replacing a dead HIPRO. But then, this week (January 15th, 2020) it started emitting a horrible, awful industrial/chemical smell, and the MediaSmart Server began turning itself off for protection. I've taken this PSU out of the server and will never use it again. It was hot to the touch when I removed it, even a few minutes after the system had powered off. Doesn't seem like the motherboard is damaged, thankfully. This thing could have started a fire, or melted the other components in the machine. Would give zero stars if I could.
