LiteOn PA-4111-1 110W Proprietary Desktop Power Supply Dell 333s/L 100-240V

The LiteOn PA-4111-1 is a 110W proprietary internal desktop power supply manufactured by Taiwan Liton Electronic Co., Ltd. It was originally fitted in Dell 333s/L small desktop systems and uses a proprietary connector configuration specific to that platform — not a standard ATX pinout. The unit features universal voltage input, accepting both 100–127V and 200–240V AC supply, making it suitable for use in North American and international-voltage environments.

Applications

The PA-4111-1 is a direct replacement power supply for Dell 333s/L small desktop systems. Dell's early-to-mid 1990s compact desktop line used proprietary internal power supplies with non-standard connector layouts, meaning this unit is not a drop-in replacement for standard ATX systems — it is purpose-built for the Dell 333s/L chassis. These units are sought by technicians and collectors maintaining legacy Dell desktop hardware, where the original PSU has failed and a like-for-like replacement is needed. The universal voltage input range also makes it usable in regions with 200–240V mains supply.
