Dell PowerEdge Comes from China factory,Cheap and high quality
Workstations are just in the professional environment very popular workplace computer , as they have more power than, for example a desktop PC. I would not plug both sides of a device into a single UPS and consider that safe. For example, my computer has a 450W power supply, which would require a 630VA-rated UPS (450×1.4) and a 17-inch monitor that is rated in amps, not watts. Beyond that, any supply that provides the correct voltage and AT LEAST enough current (amperes) will work. I'm not new to computers or building them, at all, but there are some things I never got around to learning everything about; power supply units are a good example of such a thing.
From all the reading I have done, I think I may know what I need to in order to power this board. HP Compaq SFF small ATX Power Supply Identical to ATX pinout, but use smaller connector and PSU form-factor is incompatible. If the system monitor functions in the system BIOS do not display voltage levels (refer to Figure 4-10 for an example of a system that does display voltage levels in the BIOS), you can take the voltage measurements directly from the power supply connection to the motherboard.

IME, the modem is the most fragile part, and a bad modem can stop a PC from starting up. Also, lightning strikes tend to hit the phone line more often than the power line, IME. Power the laptop on. Should the laptop fail to power on, the power adapter is incorrectly working and should be replaced. This means I can't (easily) add another hard drive or a floppy drive (or something that uses that power connector, like a bluetooth adapter, or a card reader.) I have no plans to add any other accessories.
Whip out your calculator and add up the wattage ratings for everything connected to your computer that uses the power supply, including the motherboard, processor, memory, cards, drives, and bus-powered USB devices. If you want to replace just the Dell motherboard, you're out of luck unless you get your replacement board from Dell. Before you start to worry about replacing the power supply, ensure that the power failure is not caused by a general power failure from your power service provider.
A true testament of this would be the redundant power supplies for the Dell Poweredge 1800 server. Static from the interconnecting of parts inside the computer can sometimes have an adverse effect on the computer's power supply. It slowly got worse and worse until the computer began freezing and forcefully rebooting. Output specifies the characteristics of the power provided by the power supply to your computer.<img class='alignleft' style='float:left;margin-right:10px;' src="http://bestcomputermart.com/wp-content/uploads/2016/07/Dell-3-Prong-Computer-Power-Supply-Cord-For-Computers-Monitors-Standard-US-Outlet-YVL-PN-1874571-0-250x250.jpg" width="281" alt=""/>
