Thanks for replying....Let me rephrase my question..... After adding new GPU and PSU my power consumption will obviously surge(including the monitor) which can be handled by my UPS during power.My UPS used to back up for two minutes before shutdown(5 Minutes if I switch off my monitor) before this upgrade.... But with untimely powercuts in India, If the system suddenly gets switched off before shutdown , there may be problem of any hardware failure.... this is faced by tier 2 and tier 3 cities frequently.......
