Delta Electronics DPS-100BB 103W AT Power Supply 115V 230V 50/60Hz Vintage 1985
The Delta Electronics DPS-100BB is a 103W AT-form-factor desktop computer power supply manufactured in 1985 (date code 8547). It features a dual-voltage AC input accepting both 115V and 230V at 50/60Hz, making it compatible with both North American and international power standards. The unit connects via standard AT-style P8/P9 Molex connectors and includes an IEC C14 inlet with an IEC C13 pass-through outlet and a rear-mounted rocker on/off switch.

Applications
The AT power supply form factor was the standard for IBM PC/XT and PC/AT compatible desktop computers throughout the mid-1980s to mid-1990s, before the ATX standard replaced it around 1995. Units like the DPS-100BB powered the original IBM PC/AT clones and early 286/386-era machines from manufacturers including Multitech (the precursor to Acer), leading PC clone makers of the era. The IEC C13/C14 inlet and pass-through outlet were characteristic of AT-era designs, allowing a monitor to be daisy-chained from the same AC circuit. Today, the AT power supply is sought after by vintage computer collectors and restorers working on period-correct 8088, 8086, 286, and early 386 systems. The 103W output was typical for machines of this generation, which had modest power demands compared to modern hardware. The dual-voltage input also makes this unit useful for international restorations or machines configured for 230V operation.
This Delta Electronics DPS-100BB 103W AT desktop power supply has been bench-tested at our facility and is in good working condition. The metal case shows light cosmetic wear consistent with its vintage 1985 manufacture date — some minor surface scuffing on the housing — but the unit is fully functional. The rear panel includes an IEC C14 AC inlet, an IEC C13 pass-through outlet, and a rocker on/off switch. The AT-style wiring harness with Molex power connectors is attached and intact.
