Questions about this item

How do I install this power supply in a Compaq Presario SR1600 series desktop, and what step is often missed?

Remove the side panel, disconnect the old unit's cables from the motherboard and drives, unscrew the four rear mounting screws, slide the new Logisys unit in, secure it with those screws, then reconnect every cable — the step often missed is plugging in the four-pin CPU power connector near the socket.

What maintenance or replacement will this power supply need later?

The internal cooling fan is the only moving part; after several years of continuous use its bearings can wear and become noisy, so plan to clean dust from the intake grille annually and replace the whole unit if the fan fails or voltages drift.

What limit appears first when this power supply runs under sustained load?

The unit's rated wattage ceiling is reached before thermal protection triggers, so if the combined draw of the motherboard, drives and add-in cards exceeds that rating the system will shut down or become unstable.
