Mac Pro won't turn on
The LEDs on the memory banks lit up for a fraction of a second, much shorter than they normally do. A brief whistle sound came on. The UPS display indicated a power draw of 9 Watts, then 8,7,6 and so on until it hit 0. Pressing the power button again didn't do anything. When I removed the power cord and reconnected it again, pressing the power button resulted in the same as above.
This seems to point to the power supply, doesn't it?
Mac Pro 1.1, iBook G4, MacBook, Mac OS X (10.5.8)
