Questions about this item

Will the Z890 TUF motherboard and LGA 1851 socket accept my existing DDR5 memory kit?

The board has four DDR5 slots and supports up to 192 GB, so your current DDR5 modules will work provided they match the platform's speed and voltage requirements.

How can I confirm the RTX 5090 32GB is running at full PCIe 4.0 x4 bandwidth after assembly?

Open GPU-Z or the NVIDIA control panel and verify the link width shows x4 and the memory reads 32 GB; the Samsung 990 PRO SSD also negotiates PCIe 4.0 x4 for reference.

Which items ship inside the Antec P20 case and what must I source separately?

The system arrives fully assembled with the 20-core Ultra 7 265K, 128 GB DDR5, 4 TB 990 PRO SSD, 10 TB HDD, RTX 5090 32 GB, 1000 W Gold PSU, 240 mm AIO, Windows 11 Pro, WiFi7 and Bluetooth5.4; only a display, keyboard and mouse are needed.
