Direct replacement for legacy Compaq systems

The Replace Power RPSU-C99-40 is an ATX power supply designed specifically for Compaq Presario models SR2032X, SR2034NX, SR2037X, SR2050NX and SR2054X. It accepts switchable input voltage of 110V or 220V and fits a reduced depth of 5.9 inches height by 3.4 inches width. Grey casing and a single 80mm fan complete the unit.

Connector set covers older peripheral mixes

The bundle includes one SATA connector, one 20+4 pin ATX motherboard connector, one 12V ATX connector, two large power connectors and one 6-inch small power connector. Over current, over power and over voltage protection circuits guard attached hardware. This selection lets the unit serve mixed IDE and SATA drives without extra adapters.

Rated at 40W continuous output

The 40W rating supplies enough headroom for basic office workloads and legacy components in the listed Presario chassis. It will not support modern discrete graphics cards or high-wattage processors. Builders needing more power for upgrades should look elsewhere.

Perguntas sobre este artigo

Will the 80 mm fan need cleaning or replacement after extended use?

The single 80 mm fan is the only moving part; dust buildup can reduce airflow so periodic cleaning with compressed air is recommended, and the fan can be swapped if it becomes noisy or fails.

Which protection circuit is likely to trip first during continuous full-load operation?

Over Current Protection and Over Power Protection monitor output rails and will shut the unit down if sustained draw exceeds the 40 A combined 12 V limit.

How loud and hot does the unit get when running all day?

The 80 mm fan spins at a constant speed, producing moderate audible airflow; the chassis reaches warm temperatures but stays within normal operating range for an ATX supply.
