Thanks for the replies. I been doing some reading, and have tried resetting the PMU, and reseating things with no change. My question is: could a bad battery cause this behavior? I'll try replacing that while I look into buying a new supply; it couldn't hurt, I don't know how long it's been there.<br>

Would incompatible firmware cause the Power strip breaker to trip?<br>
The SD is powered by the computer PSU so +1 for Power supply<br>
