Nettet19. aug. 2015 · Hold-up time refers to the total amount of time a power supply unit (PSU) of a computer continues to operate in case of a power failure. It is the time until which the PSU can provide a consistent voltage necessary to keep a computer powered up. Nettet4. feb. 2024 · Figure 3: Hold-up time versus output load for the CUS1500M-12 power supply . As the value of C1 in the CUS1500M-12 is much larger, if the power supply only supplied 10% of its rated output current (150W), the hold-up time would be over 200ms. This is a very simple solution, but using a 1500W power supply would be larger and …
