Questions about this item

What ATX form factor does the ACE-841AP use for mounting in a standard case?

The unit follows the ATX form factor, so it fits any chassis with standard ATX power-supply mounting holes and the usual four-screw pattern.

Which connectors must be seated first during installation to avoid a no-post condition?

Insert the 24-pin main motherboard connector and the 4-pin or 8-pin CPU power connector firmly until they click; missing either one is the most common reason the system will not start.
