Delta P ADP-310AF 310W PSU for 27" A1312 iMac

This Delta P ADP-310AF unit is a 310 W power supply built for the 27 inch A1312 iMac and compatible model numbers including MB952LL, MB953LL, MC507LL, MC510LL, MC511LL, MC784LL, MC813LL, MC814LL and MD063LL. It serves owners who need a direct replacement for the original internal PSU. Builders working on non-Apple chassis or requiring modular cabling should look elsewhere.

Thermals, noise and power draw

The supply is rated for a maximum output of 145 W and operates without any fans, so it runs silently under normal load. Its fanless design eliminates moving-part noise and reduces dust intake inside the all-in-one enclosure. Power draw scales with the system components rather than the PSU itself.

What the bundled accessories

No accessories, cables or software are included with this unit; it is supplied as the bare power-supply module only. Installation relies on the existing connectors and mounting points already present in the A1312 chassis. The lack of extras keeps the replacement straightforward for technicians familiar with the platform.

Questions about this item

How do I install the ADP-310AF in a 27" A1312 iMac, and what step is often missed?

Remove the display panel, disconnect the old unit, fit the ADP-310AF using the original screws, then reconnect the AC inlet and logic-board cables; the step often missed is re-seating the vertical sync cable behind the power board.

What maintenance or replacement will this 310W supply need later?

The fanless design has no moving parts to service; only the internal electrolytic capacitors age, so plan to replace the entire unit if voltages drift or the system becomes unstable after several years.

What limit appears first when the ADP-310AF runs under sustained load?

The 145 W maximum power rating is the first limit; continuous draw above that level will trigger the protection circuit and shut the supply down.
