Ready-to-game desktop

The Adamant Custom system ships with Windows 11 Pro installed and an AMD Ryzen 7 9800X3D processor paired with an Nvidia GeForce RTX 5090 graphics card. It targets enthusiasts who want a complete high-end gaming machine without assembling parts themselves. The 32GB DDR5 memory and 4TB NVMe SSD are already configured for immediate use.

Verify power and space

Your electrical circuit must support a 1200W power supply drawing sustained load. The Mid Tower case measures 508mm deep, 203mm wide and 508mm high, so confirm your desk or shelf accommodates those dimensions. The motherboard provides rear USB4 ports at 40Gbps and USB 10Gbps ports, so check that your peripherals match those interfaces.

Liquid-cooled core with expansion room

A 240mm liquid cooler handles the CPU while the case includes front 200mm ARGB fans, a rear 120mm ARGB fan and a dedicated 120mm GPU fan for airflow. Four memory slots total allow growth up to 192GB DDR5. Four M.2 connectors and internal 3.5-inch and 2.5-inch bays provide additional storage lanes. Wi-Fi 7 and 2.5Gbps LAN give wireless and wired network options.

Questions about this item

Does the PC ship with a keyboard and mouse, or do I need to buy them separately?

The system includes only the tower with Windows 11 Pro installed; keyboard, mouse and monitor must be purchased separately.

Is the 32 GB DDR5 kit the maximum this board supports, or can I add more later?

The motherboard has four slots and supports up to 192 GB, so the installed 32 GB kit leaves three slots free for future expansion.

What real-world benefit does the 96 MB L3 cache on the Ryzen 7 9800X3D give in games?

The large 96 MB L3 cache reduces memory latency, helping the 8-core CPU keep frame rates high at 4.7 GHz base and up to 5.20 GHz boost in modern titles.
