Purpose-built workstation

This desktop combines a 12-core AMD Ryzen 9 9900X processor with 128GB of DDR5 memory and an Nvidia RTX PRO 4500 Blackwell graphics card carrying 32GB of video memory. It targets engineers, designers and researchers who need reliable performance for CAD modelling, simulation and AI learning workloads in a single system.

Storage and cooling impact

A 4TB Samsung 990 PRO NVMe drive delivers read speeds up to 7450 MB/s and write speeds up to 6900 MB/s, while a 10TB hard drive with 256MB cache adds high-capacity bulk storage. A 240mm liquid cooler keeps the CPU at stable temperatures during sustained compute tasks without excessive noise.

Platform and interface limits

The X870 motherboard provides PCI Express x16 for the GPU, four M.2 connectors and SATA 6Gb/s ports, with maximum memory support of 192GB. Rear I/O includes 2.5G Ethernet, Wi-Fi 7 and USB4 at 40Gbps, while the 850W Bronze-rated power supply sets the ceiling for total system power draw.

Questions about this item

How long before the 240mm liquid cooler needs service or replacement?

The 240mm Quiet Edition AIO is a sealed unit with no user-serviceable parts; plan to replace the entire cooler if pump noise or CPU temperatures rise after several years of continuous operation.

Which limit appears first during sustained all-core workloads — the 850W Bronze PSU or the 240mm AIO?

The 240mm liquid cooler reaches its thermal capacity before the 850W 80 PLUS Bronze supply hits its continuous rating, so CPU clock speeds will throttle first under prolonged heavy loads.

What noise and heat levels should I expect when the system runs 24/7 with the 120mm and 140mm fans active?

The Antec P10 FLUX case uses sound-dampening panels and a fan-control button; the 140mm PSU fan and four 120mm case fans run at low RPM for quiet operation, while the liquid cooler keeps the Ryzen 9 9900X at modest temperatures during all-day workloads.
