On this size power supply it's normally 115v / 240v. Then check the UPS, if the UPS only kicks in below the tolerance of the power supply, 115V, then a brownout will kill the drives. Get a better UPS or a power supply that has a greater tolerance. 700W power supplies, although expensive, normally handle the correct variance. -- Gerhard Groenewald
