Direct Replacement ATX Power Supply

The COMPAQ Presario SR5900 series ATX power supply is a new direct replacement for the SR5908F desktop model. It restores reliable power delivery to a compatible system without modification. Builders upgrading or repairing this specific chassis can install it using the standard ATX form factor.

Wide-Range Input With Single Fan Cooling

The unit accepts a wide input range of 100-120V at 10A or 200-240V at 5A across 50/60 Hz mains frequencies. A single internal fan manages thermals during normal desktop workloads. The grey enclosure weighs 2.25 units and fits the original mounting points.

Stable Output Under Continuous Load

Under sustained load the supply maintains steady voltage rails within ATX specification for the SR5908F platform. The single fan increases airflow to match thermal demand without exceeding design limits. It is not suited for systems requiring auxiliary PCIe power connectors or higher total wattage than the original configuration.
