Applications
ATX power supplies like the NPS-250CB A are the standard internal power source for desktop personal computers, converting AC mains power into the regulated DC voltages required by PC components. The ATX standard, introduced by Intel in 1995, defined the connector pinout and form factor that became universal across desktop PCs through the late 1990s and 2000s. A 250W unit at this output profile is well-matched to mid-range desktop systems of that era — Socket 370, Socket A, and early Socket 478 platforms — powering a single processor, one or two hard drives, optical drives, and standard expansion cards. These supplies are commonly sought as direct replacements in older desktop systems, small form-factor towers, and legacy workstations that share the same ATX footprint and power requirements.
This Newton Power NPS-250CB A 250W ATX power supply has been bench-tested at our facility and is in good working condition. The unit powers on normally and outputs stable voltages across all rails (+5V, +12V, +3.3V, and +5VSB). The housing shows minor scuffs and light wear consistent with prior desktop use, but there is no damage to the casing, fan, or connector harness. All power connectors — including the 20-pin ATX main, 4-pin Molex drives, and floppy power leads — are present and in good condition.
