Compaq Presario SR2100 power supply

This ATX power supply is built as a direct replacement for Compaq Presario SR2100 series desktop computers. It matches the original form factor and connector layout so the system powers on without adapter cables or case modifications. The grey enclosure houses a single cooling fan. It is sold new and ready to install.

Fits listed SR2100 models only

The unit suits owners of the specific Presario models named in the compatibility list who need a like-for-like ATX replacement. Builders working on other Compaq lines, custom chassis or proprietary small-form-factor systems should look elsewhere because the mounting points and wiring harness are tailored to the SR2100 family.

ATX form factor with single fan

The power supply follows the standard ATX footprint and uses one fan for airflow. This physical specification determines whether it will sit correctly in the SR2100 chassis and align with the rear cut-out.

Questions about this item

How noisy is the single fan when the PSU runs continuously in a Compaq Presario SR2100?

The unit uses one fan in a standard ATX layout; typical office workloads keep it at a low, steady hum that stays in the background.

Which power connectors must my motherboard and drives already provide for this SR Series unit to work?

It follows the ATX form factor, so the board needs a 20- or 24-pin main connector plus standard 4-pin peripheral leads for drives.

Will this replacement PSU fit the original SR2100 chassis and mounting points without modification?

Yes — it is built as a direct ATX upgrade for every SR2100-series model listed, aligning with the stock screw holes and rear cutout.
