Questions about this item

How do I install this 400W ATX power supply into the SH SB-4120X and which step is often missed?

Mount the unit in the chassis with the four ATX screws, connect the 24-pin main and 4-pin CPU cables, then verify the voltage selector switch matches your mains supply before powering on.

Clean the intake grill and fan blades with compressed air every six to twelve months to prevent dust build-up; replace the entire supply if voltages drift or the fan becomes noisy.
