Replacement ATX Supply for Dell Optiplex

This 300W ATX power supply replaces the original unit in Dell Optiplex M8802, M8805, M8806, C9962 and 620 systems. It delivers +5V, -5V, +12V1, +12V2, +3.3V, -12V and +5V-SB rails from a grey chassis. The reduced-depth form factor fits the tight space inside those chassis. Hi-Pot testing and low ripple specification target stable office workloads.

Connectors and Build Integration

A single 24-pin (20+4) ATX connector powers the motherboard while a P4 4-pin plug feeds the CPU. Three SATA 15-pin connectors, three LP4 4-pin plugs and one floppy 4-pin connector cover legacy and current drives. AC input accepts 110/220V at 47~63Hz so the unit works on global mains without a switch. One internal fan handles airflow in the compact enclosure.

Sustained Load Behaviour

Rise time stays below 70ms and hold-up time is rated at 17ms minimum at nominal input, giving the system a brief ride-through during mains dips. The 60/50Hz frequency rating matches standard line frequency. Continuous output is rated at 300W across the combined rails rather than a short peak figure. Builders needing higher wattage or additional PCIe power for discrete graphics should look elsewhere.

商品問答

How much hold-up time does the FSP300-ATXPA-6 provide at nominal load?

The unit delivers a minimum hold-up time of 17 ms at nominal input, giving the system a brief window to ride through short mains interruptions.

What is the typical noise and heat profile when this supply runs continuously?

A single internal fan cools the 300 W unit; with low ripple and noise specified, acoustic output stays modest during all-day operation.

Which Dell Optiplex models already have the correct mounting and wiring for this replacement?

The supply is a direct upgrade for Dell Optiplex M8802, M8805, M8806 and C9962 (620) chassis.
