Questions about this item

Will the DPS-500AB-32A power supply work with my older motherboard that uses a 24-pin ATX connector?

Yes, the unit is an ATX-type power supply designed to fit standard ATX cases and connect to a 24-pin motherboard socket.

How can I confirm the Zero RPM fan mode is active after I install the PSU?

When the system is under light load the cooling fan will stop spinning completely, so you should hear no fan noise at idle or during basic desktop tasks.

Which cables come attached to the DPS-500AB-32A and what must I source separately?

The power supply has a fixed cable set including the 24-pin motherboard and 4+4-pin CPU connectors; any additional peripheral or drive cables would need to be purchased separately.
