  2. Once the side panel is removed, locate the PSU’s mounting screws. There are typically four screws, but your case may have more or fewer.
  3. Remove the PSU’s mounting screws and carefully pull the PSU out of the case. Be careful not to touch the PSU’s internals or any exposed circuitry.
  4. Locate the modular cables you’ll need to route behind the motherboard tray. The RM850x has eight modular connectors, so you’ll need to select the appropriate cables for your system.
  5. The cables start at the top of the case and work your way down the route. Route the 24-pin ATX power cable first, followed by the 8-pin EPS power cable.
  6. Next, route the modular cables for your system’s storage devices. For example, if you’re using an SSD and a hard drive, you’ll need to route the SATA power cables.
  7. Finally, route the modular cables for your system’s graphics card(s). For example, if you’re using a Radeon RX 480, you’ll need to route the 8-pin PCI Express power cable.
  8. Once all cables are routed, replace the side panel on your computer case.
