Built for 12-core workloads

This Adamant Custom desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 32GB of DDR5 memory and a 1TB Samsung 990 PRO NVMe drive. The system ships with Windows 11 Pro and uses integrated Radeon graphics through HDMI and two USB4 ports. It targets creators and developers who need strong multi-threaded performance without a discrete graphics card.

Sustained multi-threaded throughput

A 240mm liquid cooler keeps the 12-core CPU near its 5.50 GHz boost clock during long renders, compiles or simulations. The Thermaltake Smart 850W 80 PLUS Bronze supply delivers stable power with over-voltage, under-voltage, over-power and short-circuit protection. Wi-Fi 7 and 2.5Gbps Ethernet maintain low-latency network transfers while the 128 MB L3 cache feeds the cores continuously.

Tower chassis with front and rear I/O

The Corsair 4000D tempered-glass case measures 490 x 239 x 486 mm and holds two 3.5-inch and two 2.5-inch internal bays for future storage. Front panel offers one USB 3.2 Type-C port, two USB 3.2 Gen1 ports and an audio combo jack. Rear I/O adds two 40Gbps USB4 ports, one USB 10Gbps port, three USB 5Gbps ports, four USB 2.0 ports and Intel 2.5Gb Ethernet.

Questions about this item

How loud and hot does the 240 mm liquid cooler keep the 12-core Ryzen 9 9900X3D during all-day loads?

The 240 mm Quiet Edition AIO uses a 140 mm low-noise fan and is paired with an 850 W 80 PLUS Bronze PSU that also runs an ultra-quiet 140 mm fan, so both CPU and power supply stay cool with minimal acoustic output.

Which display cables or adapters must I already own to use the integrated Radeon graphics?

The motherboard provides one HDMI port and two USB4 Type-C ports that carry video, so you need either an HDMI cable or a USB-C-to-DisplayPort/HDMI adapter for your monitor.

Can I keep my existing SATA SSDs or hard drives and install them inside the Corsair 4000D case?

Yes — the case includes two 3.5-inch and two 2.5-inch internal bays, and the X870 motherboard supplies four SATA 6 Gb/s ports for additional drives.
