Up for sale is an original, proprietary power supply unit (PSU) pulled from a working IBM PS/2 Model 50 Z (Type 8550).
​Details:
​Model/Part Number: 90X9527 (FRU 90X9366)
​Wattage: 94 Watts
​Input: 110-220VAC (Auto-sensing)
​Compatibility: Specifically designed for the IBM PS/2 Model 50 and Model 50 Z. This is a proprietary "tool-less" design that slides into the chassis and connects directly to the motherboard via an integrated edge connector.
​Condition & Testing:
​WORKING PULL: This unit was tested prior to removal and provided stable power to the system, including the 60MB ESDI hard drive and expansion cards.
​PHYSICAL STATE: Very clean condition with minimal dust. The iconic large red flip-switch is firm and functional. No bulging capacitors or abnormal odors.
​Why Buy This PSU?
The power supplies in the PS/2 series are unique; they do not use standard ATX or AT connectors. If your Model 50 has a "dead" switch or no power, this original IBM replacement is the only way to get it running without dangerous and complex modifications.
​Shipping & Handling:
This is a heavy, solid unit (approx. 8 lbs). It will be securely padded and shipped in a heavy-duty box via USPS or UPS Ground to ensure safe delivery.
