A Detailed Look
(Antec CP-1000 and Antec TruePower ATX)
As we mentioned earlier, the Antec CP-1000 PSU features a unique CPX form factor that is larger than a standard ATX power supply. Because of the unusual size the CP series power supplies will only fit in a few cases that have been specifically designed to accept them. Currently these include the Antec Tweleve Hundred, P183 and P193 enclosures.

All three Antec cases come with a PSU adapter plate installed, which allows mounting a standard ATX power supply. Removing the adapter plate allows mounting a CP series PSU. Here are a couple pictures of the CP-1000 installed in an Antec P193 enclosure.
