System Overview

This Adamant Custom gaming desktop pairs a 12-core Ryzen 9 9900X3D processor with 192GB of DDR5 memory and a 4TB NVMe solid-state drive. Integrated Radeon graphics handle display output through HDMI and USB4 ports. The system arrives with Windows 11 Pro installed and is aimed at users who need high core counts and large memory capacity for workstation tasks or heavy multitasking.

Build Integration

The mid-tower case measures 477mm deep by 220mm wide by 486mm high and includes a 240mm liquid cooler for the CPU. A Thermaltake 850W 80 PLUS Bronze power supply provides power, while the PRIME X870-P motherboard offers rear I/O with two USB4 ports at 40Gbps, one USB 10Gbps port, three USB 5Gbps ports and four USB 2.0 ports. Internal expansion includes four M.2 connectors and two SATA 6Gb/s ports, with drive bays for three 3.5-inch and three 2.5-inch devices.

Sustained Operation

Under continuous load the 240mm liquid cooler and case airflow — three 120mm front fans, one 120mm PSU-shroud fan and one 120mm rear fan — manage CPU thermals. The 128MB L3 cache and 192GB DDR5 configuration support prolonged compute workloads without memory pressure. The Samsung 990 PRO SSD delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s for sustained data throughput. Intel 2.5Gb Ethernet and Wi-Fi 7 2x2 with Bluetooth 5.4 maintain network connectivity during extended sessions.

Questions about this item

How does the 240 mm liquid cooler handle the 9900X3D when all 12 cores run at 5.50 GHz for hours?

The 240 mm Quiet Edition AIO is paired with a 120 mm rear fan, a 120 mm PSU shroud fan and three 120 mm front fans inside the sound-dampened Antec P10 FLUX case to move heat away from the CPU continuously.

What is the typical noise level from the cooling system when the 850 W PSU and case fans are running all day?

The Thermaltake Smart 850 W unit uses a 140 mm ultra-quiet fan and the case includes a fan control button so you can balance airflow against acoustics during long sessions.

Which display cable do I need to connect a monitor to the integrated Radeon graphics?

The motherboard rear I/O provides one HDMI port and two USB4 ports that carry DisplayPort Alt Mode, so a standard HDMI cable or a USB-C to DisplayPort cable will work.
