In 2019 Intel released a new standard based on an all-12V design: ATX12VO. The power supply only provides 12 V voltage output; [13] 5 V, 3.3 V powers, as needed by USB, hard disk drive and other devices, are transformed on the motherboard; and the ATX motherboard connector is reduced
PC power supplies often provide a power good signal to the motherboard; the absence of this signal prevents operation when abnormal supply voltages are present. Some SMPSs have an absolute limit on their minimum current output. [2] They are only able to output above a certain power level and cannot function below that point.
If the output is required to be isolated from the input, as is usually the case in mains power supplies, the inverted AC is used to drive the primary winding of a high-frequency transformer. This converts the voltage up or down to the required output level on its secondary winding. The output transformer in the block diagram serves this purpose.
The 7500 introduced a new case design, [2] later dubbed "Outrigger" by Mac enthusiasts. There were two derivative models: the Power Macintosh 7600 , identical to the 7500 except for the CPU which was a PowerPC 604 or 604e processor instead of the 7500's 601 ; and the Power Macintosh 7300 , identical to the 7600 but without the video inputs ...

The original IBM PC could be equipped with as little as 16 KB of RAM and typically had between 64 and 640 KB; depending on the amount of equipped memory, the computer's 4.77 MHz 8088 required between 5 seconds and 1.5 minutes to complete the POST and there was no way to skip it.
