Questions about this item

Will the 15-inch SATA connector reach my drive bay in a standard ATX case?

The unit includes one 15-inch SATA power connector, which is long enough for most mid-tower drive cages.

Does the 14-inch ATX connector support both 20-pin and 24-pin motherboards without an adapter?

Yes, the single 14-inch ATX power connector is keyed to fit either 20-pin or 24-pin sockets directly.

How often should I clean the 80mm cooling fan to keep airflow steady?

Vacuum the fan intake every six to twelve months; the grey housing removes with four screws for deeper cleaning.
