Applications
The HP Vectra line was HP's business-class IBM PC-compatible desktop series, introduced in the mid-1980s and running through the early 1990s. The Vectra 286 used an Intel 80286 processor and HP's proprietary chassis and power supply design — the ATX standard had not yet been adopted, so each manufacturer produced its own form factor. This 45935-60231 supply is the correct replacement or spare for Vectra 286 systems still in service, restoration projects, or legacy industrial applications where Vectra hardware remains in use. Because HP used a proprietary connector and pinout, standard AT or ATX power supplies are not direct substitutes; this original HP unit is the correct solution for keeping a Vectra 286 running. Collectors, legacy system maintainers, and industrial users keeping older HP workstations operational are the primary buyers for this type of supply.
This HP 45935-60231 ETX-661E16M Vectra desktop power supply has been bench-tested at our facility and is in good working condition. The metal chassis shows light surface wear consistent with used equipment, and the Panaflo brushless cooling fan, IEC inlet/outlet, and output wire harness all appear intact and undamaged. Made in Singapore; UL, TÜV, and CSA certified. Please view our photo set and contact us if you have any questions.
