180 W Power Board for iMac G5 20

This internal power cable assembly replaces the original supply board in the 20-inch iMac G5. It carries the A1076, AP14P46, AP13PC97 and Q45B part references and the DPS-180SB A designation. The unit is intended for repair technicians and owners restoring a single machine. It is not for builders needing a standard ATX power supply or a different form factor.

Thermals, noise and power draw in normal use

The board delivers up to 180 W to the logic board and display components. Because it has no integrated fan, operational noise depends entirely on the host system's cooling design. Power consumption matches the load presented by the iMac G5 hardware. No independent thermal or acoustic figures are supplied for the board alone.

Highlights

  • Direct replacement for iMac G5 20" PSU
  • 180 W output matches original specification
  • 20 inch cable length fits chassis exactly
  • Includes AP14P46 and AP13PC97 connectors

Questions about this item

How do I install the A1076 power board into my iMac G5 20 inch?

Disconnect the AC lead, open the rear casing, unplug the AP14P46 and AP13PC97 connectors from the old board, remove its mounting screws, fit the replacement DPS-180SB board, reconnect both cables firmly, then reassemble.

What maintenance will the DPS-180SB power board need over time?

Blow dust from the board and heatsink area periodically; inspect the Q45B section for bulging capacitors and replace the entire board if any appear.
