Core specification

This system centres on a 12-core AMD Ryzen 9 9900X3D processor with 128 MB L3 cache and a 5.50 GHz boost clock, paired with an Nvidia GeForce RTX 5080 graphics card carrying 16 GB video memory. A 240 mm liquid cooler handles CPU thermals inside a mid-tower chassis. 32 GB DDR5 memory and a 4 TB Samsung 990 PRO NVMe drive complete the main hardware set.

Intended use and limits

The configuration suits professionals who need high single-thread speed and large cache for simulation or compilation workloads, plus GPU compute for rendering or AI inference. Buyers who require more than 32 GB memory out of the box, additional internal drive bays beyond the four M.2 slots, or a larger power supply than the fitted 1000 W unit should consider other options.

Deciding specification

The CPU delivers 12 cores and 24 threads with a 128 MB L3 cache, a combination that directly determines throughput in cache-sensitive applications and frames per second in CPU-bound titles.

Questions about this item

What case clearance does the 240 mm AIO radiator need?

The Antec P20 mid-tower measures 469 x 220 x 490 mm and supports a 240 mm radiator at the front or top; verify the chosen mounting point has at least 240 mm length clearance.

Which motherboard power connectors must be seated for the Ryzen 9 9900X3D and RTX 5080?

Connect the 24-pin ATX cable and both 8-pin EPS cables to the PRIME X870-P, then attach three 8-pin PCIe cables from the Thermaltake 1000 W unit to the RTX 5080.

How many M.2 slots remain free for future SSD upgrades?

The PRIME X870-P provides four M.2 connectors; one is occupied by the Samsung 990 PRO 4 TB drive, leaving three open slots for additional NVMe storage.
