Questions about this item

How do I install the PS-4241-1HC power supply in my EliteDesk 800 G1 SFF and which step is often missed?

Remove the side panel, unplug the 24-pin and 4-pin cables from the old unit, unscrew the four retaining screws, slide the new PS-4241-1HC into the chassis, refit the screws, reconnect both power cables, and ensure the 4-pin CPU connector is fully seated — it is the step most often left loose.

What maintenance or replacement will the PS-4241-1HC need over time?

The internal fan bearings will eventually wear; plan to replace the entire PS-4241-1HC unit when fan noise increases or voltages drift, as no user-serviceable parts are inside.
