Installation: Power Supply
Power Supply (ATX)
The Cooler Master Elite 110 case is designed to mount a standard, full size ATX power supply; no small feat for a mini-ITX enclosure. However, if you choose to go this route you will want to select a power supply with a small chassis (140~150mm deep preferred) and one that is either fully or semi modular (I actually prefer semi modular for tight spaces). The Elite 110 case can accept a full size ATX PSU up to 180mm deep, but cable management can quickly become a nightmare, especially if you are filling up the cube with a dual-slot graphics card and one or more 3.5” HDDs.
To make a little extra room inside, the Elite 110 case uses a mounting bracket on the back panel that bumps the PSU out the back of the case one inch.
Once the bracket is attached to the PSU, you just slide the assembly into place and secure it with four machine screws.

As you can see, things start filling up quickly with a full size power supply, dual-slot graphics adapter, and two drives mounted to the side panel. On the other hand, if you are not using an expansion card and don’t have a 3.5” HDD mounted on the left side panel, there is ample room for a full size PSU and easy cable management.
Power Supply (SFX)
Another option is to use a small form factor PSU like the 450W SFX unit shown below. It is much smaller than the 600W ATX unit used above and still has enough capacity and comes with the necessary cables (4+4 pin CPU and dual 6-pin PCI-E connectors) to support our build.
The fully modular SFX PSU comes with an ATX adapter plate, so by putting all the pieces together we come up with a very compact PSU combination.
And this leaves room for adding a water-cooling system (next section).
Note: I recommend selecting a power supply that incorporates a quiet fan that runs all the time (even at low power) to help maintain airflow through the case.
