Check your power in your house, if you are running under voltage that will
cause the issue you are experiencing. A lot of electronics will continue to run
on low voltage (including PCs) but a UPS is designed to keep power at rated
spec. This means that the UPS will draw power from it's battery to supplement
low power. Just like when a UPS turns off after a power outage when the battery
is drained it will do the same if the battery is drained and you have low
power. It may allow low wattage devices to work but when it senses a load
beyond what it is able to provide it will not send power to that device. In all
likelihood your PC will power on if you connect it without the UPS unless your
PSU specifically has a low power protection. Most quality PSUs are switching
models that are able to handle voltage from 110v (US standard) to 260v and
quite a bit in between. I wouldn't recommend using your system without a UPS if
you have bad power but connecting it just to test for a brief period should be
fine.
If your power is indeed low then you will need to contact your power company
and report the issue.
