Applications
ATX power supplies in the 300W class were the standard for mainstream desktop PCs from the late 1990s through the mid-2000s, powering systems built around Intel Pentium III/4 and AMD Athlon/Duron platforms. The ATX specification standardized connector layouts and output rails, making units like the TOP-300SSA interchangeable across a wide range of tower and mid-tower cases from that era. Today these units remain useful for maintaining or repairing legacy desktop systems, powering older industrial PCs, or supplying bench power in workshop and lab settings where a regulated multi-rail ATX source is needed. The universal 115/230V input makes the TOP-300SSA compatible with both North American and international AC mains.
This GPS Top Power TOP-300SSA 300W ATX desktop power supply has been bench-tested at our facility and is in good working condition. The unit shows normal cosmetic wear consistent with prior use, including light scuffing on the metal housing. The full cable harness is present and intact, including Molex peripheral connectors and the 20-pin ATX main connector. Please view our photo set and contact us if you have any questions.
