Macintosh IIci IIcx Quadra ASTEC Replacement Pico ATX Power Supply Assembly

Description: This is the Pico version of the Macintosh IIci power supply board, Model Pacific Pico. The board is designed to be a drop-in replacement for the original top side boards so the machine does not need to be extensively modded for this replacement and thus retains the original functionality and look of the original power supply.Note: the Pico ATX board is not included with this listing. This board has been designed for a specific Astec model power supply # AA15831 (pictured in the listing as a reference), so please check the model you have and ideally you should open up the top part of the enclosure to confirm you have a match.Demo video on YouTube: Let's Hot-Rod a Mac IIciThe board design was stress tested with an RGEEK 150W Pico ATX supply and was able to run a Mac IIci outfitted with a DayStar Turbo 601 (PPC accelerator), 33M Hz 68040 Radius Rocket with 128 MB of RAM, Radius Precision Color 24XP video card, base 32 MB RAM. The Rocket was run in RocketShare mode and was run at the same time as the Turbo 601 was set to the active CPU. The IIci in this configuration draws approximately 62 W (69 W peak). The machine was run for at least an hour. It has also run a Quadra 800 in a Quadra 700 enclosure. These configurations are more demanding than the original design intent, a more modestly spec'd machine would be more appropriate.Features:- High quality internal 12 VDC 80W AC/DC converter- Designed specifically for ASTEC model # AA15831- Convenient 2.5 mm ID x 5.5 mm OD DC plug compatible with Mini-Box, RGEEK, and others (check compatibility) - Plug and play design, no soldering required- Soft power via keyboard power key or rear power button- Reuses the original power supply bottom board with AC input filtering and fuse- 12 VDC fan connection- 5 VDC monitor power AC pass-through relay connection- Optional LED indicator- Optional filtering circuit for fan connection- Optional direct AC connection with fuse and pluggable terminal connector to bypass the original bottom boardWhat you are getting:- Qty 1: Assembled and tested board (Pico ATX is not included)- Qty 1: Cable assemblyOptions like the LED indicator, fan filtering circuit, and direct AC connection are not included with this listing.
