Redundant Server Power Supply

The KHACHIMO DPS-550 800 1200AB is a redundant power supply designed for server environments that require continuous uptime. It fits standard ATX bays and carries part identifiers AC-148A and 139B for exact replacement matching. This unit suits administrators maintaining compatible rackmount or tower systems where failover capability is essential.

ATX Form-Factor Constraints

The ATX physical format limits installation to chassis built for that mounting pattern and connector layout. Redundant operation depends on a backplane or cage that accepts hot-swap modules and distributes load across units. Systems lacking the correct slot spacing or signal pins cannot use this supply, and total output is bound by the 550, 800 and 1200 ratings printed on the label.

Questions about this item

Should I choose the 550 W, 800 W or 1200 W version for my server?

Select the wattage that matches your chassis label — 550, 800 or 1200 watts — because each unit is keyed to a specific power budget.

What does the 148A and 139B rating mean once the supply is installed?

Those markings identify the exact Dell AC-148A and 139B part numbers, so the unit fits the redundant bay and reports correctly to the server management controller.
