Optiplex 3050 MT doesn't work in inverter power
I've connected my newly bought Dell Optiplex 3050MT to Numeric Digital 600Ex UPS. This UPS is in turn connected to a domestic power source which uses a power backup from Microtek 1000EB UPS. When the domestic power supply is available and it is routed through Numeric Digital 600Ex UPS, there is no issue. The system starts up and works very fine. But when there is no domestic power supply and the power comes from my Microtek 1000EB to Numeric Digital 600Ex UPS, my system doesn't starts. Only a flash of LED can be seen alternating between white and amber. Please help.

Most All Modern machines with PFC power supplies REQUIRE True Sine Wave UPS. You are Damaging the power supply using a SQUARE WAVE INVERTER. Numeric Digital 600Ex is not a Dell product and Not supported here.
1500VA/1050W is the smallest I would recommend for a Mini Tower.

The "inverter" having issues is also not a Dell Product and Made in India so its not supported here.

The "Issue" is "WaveForm: Quasi Sine Wave vs True Sine Wave Output.

See if HP and/or the mfr. of the inverter has a community forum. Neither product mentioned, HP printer, Intex inverter, is a Dell.
You might also be able to return or trade the inverter for one that does work with HP.
