If you need to replace the power supply for your Rok Box MC Full Tower PC, the process is relatively straightforward. 


If you are replacing the power supply (PSU) with the same PSU make/model, you may utilize the cables that have already been run inside the PC case, replacing only the PSU. 


PSUs in these model PCs are fully modular, meaning that they have multiple cables that plug into the back of the PSU, allowing you to replace only the PSU unit itself. 


This article outlines how to replace the PSU using a same-for-same replacement. 


If you are using a new PSU that is not the same model as that which was installed into your PC, we suggest replacing all cables using the cables included with your new PSU. 


To replace the PSU using the same PSU make/model: 


Remove both sides of the PC case. 

The PSU is at the bottom-right-hand side of the right-hand side of the case: 


Remove the four screws on the back of the PC that hold the PSU to the PC case: 



Push the PSU forward towards the front of the case, and then slide it out of the side of the PC case. 

Disconnect the cables that are plugged into the back of the PSU. They will be plugged into ports similar to this on the back: 


Then, plug the same cables into the same ports on the back of the new PSU. The cables have white text on their connectors which indicate to which port they plug. The ports are also keyed so they can only be connected to certain cables. 

Installation is the reverse of removal.
