I got my new PSU in the mail from UPS today. This has to be the 4th package in a row from UPS where half the box is smashed in. Anyway it was packed fairly decently so it shouldn't have been a problem.
I unpacked it and plugged the new PS in and the computer boots up for a half second and then shuts off. I switched it back out with the original PS, and the computer boots up fine. I called Shuttle tech support and the guy on the phone had to be stoned out of his mind. I told him I only hooked up the motherboard connections and it didn't power up, while the old one did, and he spent about an hour consulting with another technician about what could be wrong. Anyway he told me to goto their website and fill out a request for an RMA.
