may be additionally supported by the heatsink mounting holes.
It is always advisable to attach the power supply heat sink to another thermal
dissipator (such as a chassis or finned heatsink etc). The resulting decrease in
heat sink mounted component temperatures will improve power supply
lifetime.
A standard L-bracket and cover is available for mounting which contains all
screws, connectors and necessary mounting hardware. The kit is available,
