I built a gaming Rig so my old computer 380 watt APC UPS not sufficient for this new 700watt smps system. when power cuts off, ups gives red light and beeps and not giving power to computer. i have 800watt home inverter ups(microtek sebz 1100) with 200ah backup battery, in technical specification it says transfer time is <15ms. if i connect my pc directly to this invertor is this transfer time enough to keep pc running without shutting off?
