500W ATX Power Supply

Questions about this item

Does this 500 W ATX unit fit a standard ATX case?

Yes, it follows the ATX form factor so it mounts in any standard ATX chassis using the four rear mounting holes.

What is the common mistake when installing the DPS-500AB-20A?

Forgetting to plug in both the 24-pin ATX connector and the 4+4-pin CPU power cable before first boot.

When will the fan need cleaning or replacement?

The Zero RPM mode keeps the fan off at low and medium loads, so dust builds slowly; plan to clean it once a year and replace only if bearing noise appears.
