    I have my nMP plugged into a UPS (APC BackUPS Pro 1000) and whenever the computer goes to sleep, it's also supposed to put peripherals to sleep. However, 50s after they go to sleep, they power back up again, and continue cycling between sleep-mode and power-on indefinitely, until I wake the computer from sleep.

    I'm wondering if it's because the Back-UPS Pro 1000 uses Step Approximation to Sinewave instead of Power-Factor-Corrected (PFC) Sinewave.

    Does the new Mac Pro require a PFC UPS in order to function properly?
