Compaq Presario SR5400 ATX upgrade

This ATX power supply is built as a direct replacement for Compaq Presario SR5400 series desktops. It matches the original form factor and connector layout for models such as the SR5402FH, SR5410F and SR5450F. The grey finish aligns with the chassis colour of these systems.

Single-fan cooling under continuous load

A single internal fan draws heat from the unit during extended operation. The design targets the thermal profile of the original Compaq power supply, so sustained output remains stable for typical office and home workloads. No additional cooling provisions are included.

Grey ATX housing with standard mounting

The steel enclosure uses the standard ATX mounting pattern, fitting the existing screw holes in SR5400 cases. Connectors follow the original pin-out, allowing a straight swap without adapter cables. Weighing 2.25 units, it sits securely in the original power supply bay.

Questions about this item

How loud is the single fan when the unit runs continuously in a Compaq Presario SR5400 desktop?

The power supply uses one fan to move air through the chassis; noise level will depend on case airflow and system load rather than a published decibel figure.

Which power connectors must the existing motherboard provide for this grey ATX unit to work in an SR5402FH or SR5410F?

Standard ATX main power and 4‑pin CPU connectors are required; the board in these Presario models already supplies them.

Will this 2.25 kg supply fit alongside the original drive cages and expansion cards in an SR5433WM or SR5450F?

Yes, it matches the standard ATX form factor used across the SR5400 series, so it occupies the same mounting points and clearance.
