The power supply's Original IBM PC, XT and AT standards
The Original IBM PC, XT, and AT were popular computer models introduced by IBM in the 1980s. Here's an overview of the power supply standards used in these systems:
Original IBM PC: The original IBM PC, also known as the IBM PC Model 5150, was released in 1981. It featured a power supply unit (PSU) with the following specifications: ● Voltage: The power supply provided +5 volts (V) and -5 V DC voltages. ● Current: The +5 V line could provide up to 2.5 amperes (A) of current, while the -5 V line could deliver up to 0.5 A. ● Power Output: The total power output of the PSU was approximately 63.5 watts (W).
IBM PC XT: The IBM PC XT, introduced in 1983, was an enhanced version of the original PC. The power supply in the PC XT had the following specifications: ● Voltage: It provided +5 V and -5 V DC voltages, similar to the original PC. ● Current: The +5 V line could deliver up to 6 A of current, while the -5 V line remained at 0.5 A. ● Power Output: The power supply had a total output of approximately 130 W.
IBM PC AT: The IBM PC AT, released in 1984, was a more advanced model compared to its predecessors. The power supply used in the PC AT introduced some changes: ● Voltage: The power supply provided +5 V, +12 V, and -12 V DC voltages. ● Current: The +5 V line could deliver up to 6 A of current, the +12 V line up to 0.5 A, and the -12 V line also up to 0.5 ● Power Output: The power supply had a total output of approximately 130 W.
It's important to note that the connectors and pinouts of these power supplies were specific to IBM systems of that era and may not be compatible with modern power supply units or standards.
