It isn't! The first is to determine you computer needs; Server, Business Professional, Gamer, Graphic/Video Designer or Editor, etc... Then if you are going to use RAID, and other power constrains. Sum total power consumption +20% and make sure Case with Power Supply wattage is sufficient.
There are 2 easy ways to check, but both require some extra equipment. The first, and easiest, is to use a power supply tester. If and when you have one, unplug the power, emove the power supply connector from the mobo, plug that into the tester, and the results should be immediate. Most of the testers have different colored LEDs to indicate the results. The second is to connect a different power supply of the same or greater voltage to your computer, if you have one. If your problem goes away, then it was the PSU, if not, keep troubleshooting. Good luck Bob

Hardware may be damaged and files may be lost if computer systems are not properly shut down. An uninterruptible power supply, or UPS, is designed to give computer users enough time to save their files and properly shut down the system in the event of a power outage. A good UPS can be purchased cheaply and may save computer users thousands when considering the cost of replacing damaged hardware and unrecoverable data from working files.
Since you are constantly running from the enclosed battery (which is always being charged when plugged in) your computer is never exposed to power fluctuations coming from electrical source.
