Questions about this item

Can I add my older DDR5 memory modules to the four slots on the Z790 AORUS board?

The motherboard has four DDR5 slots and supports up to 192 GB total, so you can add compatible DDR5 modules to the remaining slots alongside the installed 64 GB kit.

How can I confirm the RTX A400 is recognised and driving all four MiniDP outputs after setup?

Open Windows Device Manager or the NVIDIA Control Panel; the RTX A400 4 GB should appear under Display Adapters and show four active MiniDP connectors when monitors are attached.

What accessories are included in the box and what must I source separately?

The system ships assembled with Windows 11 Pro, the Antec P20 case, 850 W PSU, liquid cooler, RTX A400 GPU, 1 TB NVMe SSD, 10 TB HDD and 64 GB DDR5; you only need to provide a monitor, keyboard and mouse.
