CPU and Memory

The Adamant Custom Business Desktop is built around an 8-core AMD Ryzen 7 9800X3D running at 4.7 GHz with 96 MB of L3 cache and 32 GB of DDR5 memory. The X870 motherboard supports up to 192 GB of RAM for future expansion. Liquid cooling keeps the processor stable during sustained workloads.

Who This Suits

Engineers and analysts who need strong single-thread speed plus ECC-capable professional graphics for CAD, simulation or multi-display setups will benefit from the RTX A400 with four Mini DisplayPort outputs. Buyers who require more than 4 GB of GPU memory or double-precision compute performance should look at a different graphics configuration.

Storage Decider

The system ships with two 4 TB Samsung 990 PRO NVMe drives in RAID 0 for 8 TB of high-speed capacity and a 10 TB hard drive with 256 MB cache for bulk data. If your active dataset exceeds 8 TB of NVMe space you will need additional M.2 slots or external storage.

Questions about this item

What thermal limit will the Ryzen 7 9800X3D hit first when all eight cores run at 4.7 GHz continuously?

The 240 mm quiet-edition liquid cooler is sized for the CPU's 8-core, 16-thread load, so the first sustained limit will be the processor's own thermal ceiling rather than the cooler's capacity.

How much fan noise and waste heat does the 850 W 80 PLUS Bronze PSU add after hours of full-load operation?

The supply uses a 140 mm ultra-quiet fan and Japanese main capacitors, keeping acoustic output and exhaust heat low even when the system draws near its rated 850 W.

Which display cables must I already have to use the RTX A400's four Mini DisplayPort outputs?

The card provides four MiniDP ports, so you need four Mini DisplayPort cables or MiniDP-to-DisplayPort/HDMI adapters matching your monitors' inputs.
