To install a 600 W single power supply module:
1. Firmly hold the power supply
module and insert it into the
power supply cage.
2. Push the power supply all the
way in until its outer end aligns
with the rear panel.
Be careful with the power supply cables when inserting the power
supply module into the cage. Due to space constraints, the cables may
get entangled with the installed components or other cables, causing
the cables to break!
3. Place the metal plate flat on the
outer end of the power supply
module, flushed to the top of the
chassis, while matching the four
hooks with their corresponding
holes on the rear panel.
