Answer to: Unexpected mains power shutdownAgree with Dan. Before I got my 1st iMac in Dec. I got learning curve advice from friends who are computer engineers. •They said iMacs are particularly sensitive to power spikes and wave form & to get a UPS (Uninterrupted Power Supply) before ever turning the iMac on. LoL I thought UPS was a delivery service. •Went for a CyberPower Intelligent LCD model (825VA) with "simulated" sine wave only because this was the model they used on their iMac but they use other brands as well. •Was told I didn't need "pure" sine wave which are considerably more expensive. •These units are roughly the same price across all brands. The price changes with volts/watts/power you need or if you go for pure sine wave over simulate. Cheers xoxo :)
