Short answer: no Long answer: It depends on the hardware. In general, there aren't sensors in PSU's which we can access, but there are some power supplies which have fan-speed monitors and/or temp sensors which we can potentially read. I'm not aware of any PSU fault sensor which is supported by an open-source project, but that doesn't mean that it doesn't exist. It may be the kind of thing which only can be accessed through a bios interface. If I were you, I'd get some technical details on how the fault detection on some rack-mount servers works. If you are lucky, they may actually disclose enough details to write a driver, or have some sort of driver already available.
