Compatible Presario SR5800 upgrade

This new ATX power supply is built as a direct replacement for Compaq Presario SR5800 series desktops. It fits a long list of specific models including the SR5807C, SR5820, SR5830, SR5840 and SR5890 families. The unit uses a standard ATX form factor with a single cooling fan and a grey finish. It weighs 2.25 units.

Suits owners of listed SR5800 models

This unit suits anyone restoring or repairing a Compaq Presario desktop from the supported SR5800 range. It matches the original ATX layout and connector placement for those chassis. Builders working on other Compaq series, custom cases or proprietary small-form-factor systems should look elsewhere. The part is not designed for servers or redundant power configurations.

ATX form factor decides fit

The single specification that determines compatibility is the ATX form factor combined with the exact model fit list. Only the SR5800 series models named in the data are confirmed to accept this unit physically and electrically. No other specification overrides this constraint. Verify your exact model number before ordering.

Questions about this item

What ATX standard does this power supply follow, and what does that limit in practice?

It follows the ATX form factor, so it fits standard ATX cases and provides the usual 24-pin motherboard and 4/8-pin CPU connectors for SR5800 series desktops.

What physical space and mounting points does this unit need inside a Compaq Presario SR5800 chassis?

The grey ATX enclosure measures to standard ATX dimensions, uses four rear mounting screws and a single built-in fan for airflow.

How is this power supply installed, and which step do people often get wrong?

Remove the old unit, slide this ATX supply in, secure four screws, then connect the 24-pin motherboard and CPU power leads; the step often missed is seating the 24-pin connector fully until it clicks.
