Rated power refers to the maximum load of a power supply under stable and continuous operation. Rated power represents the true load capacity of a power supply. For example, the rated power of a power supply is 300W, which means that when working continuously for 24 hours a day and 365 days a year, the sum of all loads cannot exceed 300W. However, in reality, power supplies have a certain degree of redundancy. For example, a power supply with a rated power of 300W can work stably and normally at 310W, but try not to use it beyond the rated power, otherwise it may cause the power supply or other computer components to burn out due to overcurrent.... more
There are mainly cross loads, surges, input voltage, ripple noise, output short circuits, overpower, conversion efficiency, power factor, response time, timing, noise, conducted radiation, leakage current, high and low temperature testing, etc.... more
The software startup and shutdown function of the power supply is achieved through the PW-OK circuit. During standby, PW-OK outputs a zero level power self-test signal to the host, and the host stops working and is in a standby state. After controlled startup, PW-OK delays for several hundred milliseconds from 0 level to+5V after the output voltage of the switching power supply stabilizes, and outputs a high-level signal to the host. This signal is equivalent to the PG signal of the AT power supply. The host detects a signal that the PW-OK power supply is intact and starts the system. If there is a power outage or shutdown during the operation of the host, the PW-OK output signal disappears several hundred milliseconds earlier than the ATX switch power supply+5V output voltage, notifying the host to trigger the system to automatically shut down before the power outage to prevent the hard disk head from not being able to move to the landing area and scratching the hard disk in case of sudden power outage.... more
There are various types of power ICs, with common characteristics including: Low working voltage: The general working voltage is 3.0-3.6V. Some operating voltages are lower, such as 2.0, 2.5, 2.7V, etc; There are also some special purpose voltage sources with a working voltage of 5V, and a few with a voltage of 12V or 28V.... more
