Dynova COP8802T 275W AT XT Desktop Power Supply 5V 12V Molex CTS Datacomm 2424
The Dynova COP8802T is a 275-watt AT-form-factor desktop computer power supply built for AT and XT class personal computers. It provides the standard multi-rail DC outputs required by AT-era systems — +5V, +12V, -5V, and -12V — delivered through a full Molex wiring harness with AT P8/P9 main board connectors and peripheral Molex drive connectors. Power is switched via an external red rocker switch mounted on a separate cable, which was the standard arrangement for AT tower and desktop cases of that era.

Applications
AT-form-factor power supplies like the COP8802T were the standard power source for IBM PC/XT and PC/AT compatible desktop computers from the mid-1980s through the early-to-mid 1990s, before the ATX standard replaced them around 1995. Unlike ATX supplies, AT units use a mechanical power switch wired in series with the AC input rather than a soft-switched standby line — the external red rocker switch on this unit is characteristic of that design. The COP8802T was associated with CTS Datacomm 2424 desktop systems and compatible AT-class machines. Today these supplies are sought by vintage PC restorers, retrocomputing enthusiasts, and anyone maintaining legacy AT-class hardware that cannot accept a modern ATX unit without a case modification. The rear IEC C13 pass-through outlet also allowed the user to daisy-chain a CRT monitor to the same switched AC circuit, which was a common convenience feature of that generation.
This Dynova COP8802T 275W AT desktop power supply has been tested and is in good working order. The stainless steel enclosure shows light surface wear consistent with prior use. The full Molex wiring harness and the external red rocker power switch on cable are included and in good condition. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
