System expansions
Connecting display adapters with additional
power supply
Fujitsu recommends ordering display adapters (GFX) together with the system s o that
they have been installed and tested in the factory. This guarantees that the wiring
meets the requirements of the respective GFX card.
For systems that are supplied without a GFX card , a standard GFX cable is enclosed in the system
accessories pack. This enables the use of a GFX card with 6 and/ or 8-pin connectors.
If you require other cab les, you can purchase these from Fujitsu. The power supply (PSU)
installed in the system can supply a continuous 18.5 A for display adapters via any power
supply. Ensure that your display adapter(s) do not req uire higher power levels.
