205W Power Board for iMac 21.5" A1311

This replacement power supply board fits Apple iMac 21.5" models identified as A1311 from 2008 through 2011. It restores power delivery to systems with designators iMac10,1, iMac11,2 and iMac12,1. Buyers repairing a failed original unit in these all-in-one desktops will find a direct match.

Verify your iMac model identifier and year

Confirm the machine shows model identifier A1311 on the base and matches one of the listed model numbers such as MB950LL/A, MC508LL/A, MC509LL/A, MC309LL/A, MC812LL/A or MC978LL/A. The board is rated at 205W and carries part references 614-0445, 661-5299, 614-0444, ADP-200DF and OT8043. Units outside this range will not be compatible.

Single board supplied without cables or tools

The package contains one power supply board only; no power cord, mounting screws or thermal paste are included. Re-use the original cables and fasteners from the iMac during installation. The board has been quality checked before shipment and is ready to fit once the correct model match is confirmed.

商品問答

Does the package include any cables, screws or mounting hardware, or just the power supply board itself?

Only the power supply board is included — one piece for the iMac 21.5" A1311. No cables, screws or brackets are supplied.

My iMac is a Mid 2011 model MC812LL/A with a 2.7 GHz Core i7 — will this 205 W board fit it?

Yes. The board matches iMac12,1 Mid 2011 MC812LL/A (2.7 GHz Core i7) and the Late 2011 MC978LL/A (3.1 GHz Core i3) among the listed part numbers 614-0444, 614-0445 and 661-5299.

What does the 205 W rating mean for daily use — will it handle the original CPU and GPU loads without shutting down?

The 205 W rating matches the original ADP-200DF specification for these iMacs, so it delivers the same power ceiling the factory supply provided for the listed CPUs and GPUs.
