(7.5) Removing and replacing the newer type of PSU

Disconnect the Mains Input and Motherboard PCB
looms from the PSU.
Undo the nut retaining the grounding cable to the chassis and
remove the cable from the stud. This is located on the floor of the
chassis in the void behind the mains inlet. Undo the M4 nut to
disconnect the grounding wire.
These two T10 Torx screws on the underside of the unit secure the
PSU to the chassis. Remove these screws and the PSU can be lifted
out of the unit.
The new PSU is a direct swap for the old one. Ensure that the green
grounding wire is re-connected securely.
