![]() It provides precise voltage regulation, delivers continuous sine wave output and isolates equipment from power problems. True on-line double conversion is the highest level of power protection available. System specifications and documentation will usually clearly highlight the need for true sine wave UPS. Non sine wave UPS units put out almost square wave output and eventually permanently damage your power supply. If you take the risk of not using true sine wave and it blows up that's on you. Remember that DOS has no SATA support, and does not understand partitions > 2Tb. If it is pulling down the boot image, but the boot is not taking place, then it points to a driver issue in the boot image. I used the most current drivers from Dell and sepearte drivers from Intel.

To boot from a CD-ROM or USB device make sure that the computer firmware (BIOS or UEFI settings) is configured to boot the right device and that the priority is correct. Dell recommends only Universal Power Supplies (UPS) based on Sine Wave output for APFC PSUs, not an approxim ation of a Sine Wave, Square Wave, or quasi-Square Wave (see UPS Te chnical Specifications). For exampleĪctive Power Factor Correction (APFC) power supply. I disagree entirely about ac from the wall being anything other than sine wave unless its a surge or other damaging output. ![]()
