Applications
The ATX power supply form factor became the dominant standard for desktop PC builds in the mid-1990s, replacing the earlier AT form factor, and remains in widespread use today. A 250W unit like the ATX-250N is well suited for older Pentium-class through early Athlon/Pentium 4-era desktop systems that draw modest power — particularly machines without a discrete graphics card or with a single optical drive and one or two hard drives. These units are commonly sought as direct replacements in legacy desktop computers, industrial PCs, and point-of-sale terminals that use the standard ATX form factor and do not require the higher wattages demanded by modern gaming or workstation builds. The dual-voltage input (115V/230V) makes the unit compatible with both North American and international AC mains.
This Component Pro ATX-250N (56.04250.G91) 250W ATX switching power supply has been bench-tested at our facility and is in good working condition. The housing shows light surface wear consistent with prior use, but the unit is structurally intact with no cracks or damage. The wire harness and connectors appear clean and undamaged.
