Built for 12-core Ryzen workloads

This Adamant Custom desktop centres on a 12-core AMD Ryzen 9 9900X3D running at 4.4 GHz with up to 5.50 GHz boost and 128 MB L3 cache. It ships with 32 GB of DDR5 memory in a four-slot layout that supports up to 192 GB total. A 4 TB Samsung 990 PRO NVMe drive delivers up to 7450 MB/s reads and 6900 MB/s writes. Integrated Radeon graphics drive HDMI and dual USB4 outputs. Windows 11 Pro is pre-installed.

Tool-free mid-tower access with pre-filled cooling

The Antec P10 FLUX case opens without tools and includes sound-dampening panels. A 240 mm quiet-edition AIO cooler arrives pre-filled and mounted on the AM5 socket. The Thermaltake Smart 850 W 80 PLUS Bronze unit uses a 140 mm fan and Japanese main capacitors. Front-panel I/O offers two USB 3.0 ports and HD audio. Builders should verify that the 477 mm depth fits their desk space and that the 240 mm radiator clearance matches the case layout.

Steady output under long sessions

Liquid cooling and three 120 mm front fans plus a rear 120 mm fan move heat away from the 12-core CPU during extended compile, render or simulation runs. The 850 W Bronze PSU provides stable rails with over-voltage, under-voltage, over-power and short-circuit protection. Wi-Fi 7 2x2 and 2.5 Gbps Ethernet keep network throughput consistent. Integrated graphics limit sustained 3D performance; buyers needing discrete GPU headroom should plan for a separate card.

Questions about this item

How can I verify the Ryzen 9 9900X3D is running at its 5.50 GHz boost after assembly?

Open Task Manager’s Performance tab or a tool such as HWMonitor and watch the core clocks under load; the 12-core processor should reach 5.50 GHz when thermal headroom allows.

What ships inside the Antec P10 FLUX case and what must I provide?

The box contains the assembled PC with 32 GB DDR5, 4 TB Samsung 990 PRO SSD, 240 mm liquid cooler, Thermaltake 850 W PSU, Windows 11 Pro, Wi-Fi 7 and Bluetooth 5.4; you only need a monitor, keyboard and mouse.

Which memory capacity should I select for this X870 platform?

The build ships with 32 GB DDR5 in a four-slot motherboard that supports up to 192 GB; choose 32 GB for gaming and everyday work, or add more later if your workload demands it.
