Applications
This power supply is a direct OEM replacement for the Dell OptiPlex GX300 desktop and the Dell Precision 210 and 400 workstations — mid-to-late 1990s Dell systems built around Intel Pentium II and Pentium III processors. The GX300 was a widely deployed corporate desktop in that era, and finding a direct-fit replacement ATX power supply for it remains a common need for IT departments maintaining legacy machines, system restorers, and parts suppliers. The HP-233SNF's proprietary Dell ATX form factor and connector layout are matched specifically to these platforms, so it is primarily sought as a drop-in replacement rather than a generic ATX unit. The universal voltage input also makes it useful for international deployments of these systems.
This Dell HP-233SNF 55079 230W ATX power supply has been bench-tested at our facility and is in good working order. The unit powers on and all output rails are functional. The chassis and cable harness are in good used condition with normal cosmetic wear consistent with prior installation. All output connectors — including the ATX 20-pin main, Molex 4-pin peripheral, and floppy connectors — are present and intact. Please view our photo set and contact us if you have any questions.
