Built for AI workstations and 4K gaming

This desktop combines a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5090 32GB graphics card. It ships with 128GB of DDR5 memory and a 2TB Samsung 990 PRO NVMe SSD. Windows 11 Pro is pre-installed for immediate professional use.

Pre-assembled with liquid cooling installed

The 240mm AIO cooler and motherboard are mounted inside the tempered-glass case before dispatch. Buyers who want more storage can populate the two spare 3.5-inch bays or the two 2.5-inch bays. The four memory slots are fully occupied, so adding RAM requires replacing existing modules.

128GB DDR5 memory capacity

This figure determines whether the system can hold large datasets, complex scenes or multiple virtual machines without swapping. The board supports up to 192GB total across four slots. If your workload needs more than 128GB today, you must plan a module swap rather than a simple upgrade.

この商品に関する質問

How do I verify the 12-core Ryzen 9 9900X3D is hitting its 5.50 GHz boost after assembly?

Open Task Manager’s Performance tab or run CPU-Z and watch the core clocks under load; sustained speeds near 5.50 GHz confirm the 240 mm liquid cooler is doing its job.

Which components ship inside the case and which must I source myself?

The case arrives fully assembled with the X870 TUF motherboard, 128 GB DDR5, 2 TB Samsung 990 PRO NVMe, RTX 5090 32 GB, 1200 W 80 PLUS Gold PSU, 240 mm AIO and Windows 11 Pro — only a monitor, keyboard and mouse are needed.

Should I choose the 128 GB DDR5 configuration or step up to the 192 GB maximum the board supports?

Stay with 128 GB if your workloads fit; move to 192 GB only when you regularly exceed 128 GB in rendering, AI training or heavy virtualization.
