Core specification

This system ships with a 12-core AMD Ryzen 9 9900X3D processor running at 4.4 GHz base frequency. The CPU provides 128 MB of L3 cache and supports boost speeds up to 5.50 GHz across 24 threads. Buyers who need more than 12 cores or a different socket should look elsewhere.

Memory and storage

32 GB of DDR5 memory is installed in a motherboard with four total slots supporting up to 192 GB. A 4 TB Samsung 990 PRO NVMe drive delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s. Buyers who want more storage bays or a different memory generation cannot use this configuration.

Build and installation

The mid-tower case measures 469 x 220 x 490 mm and includes a 240 mm liquid cooler with a 140 mm fan. The 850 W power supply uses Japanese capacitors and offers over-voltage, under-voltage, over-power and short-circuit protection. Front-panel I/O includes USB 3.0, USB 3.2 Gen 2 Type-C and audio jacks. Builders who need a smaller chassis or a higher-wattage PSU will find this unit unsuitable.

Questions about this item

What does the 12-core Ryzen 9 9900X3D at 4.4 GHz deliver in a real build?

Twelve cores and twenty-four threads with a 5.50 GHz boost and 128 MB L3 cache give strong multi-thread throughput for rendering, compilation and heavy multitasking while the liquid cooler keeps thermals in check.

How does the PCI Express x16 link and the X870 chipset shape GPU and storage speed?

The RTX 5060 runs on a full x16 lane from the CPU while the X870 platform provides four M.2 slots and USB4 at 40 Gbps, so the Samsung 990 PRO hits its 7450 MB/s read ceiling and high-speed peripherals keep their bandwidth.

What clearance and power connections does the mid-tower case require for the 240 mm AIO and 850 W PSU?

The Antec P20 accepts a 240 mm radiator up front, the Thermaltake Smart 850 W unit fits the standard ATX bay and the case measures 469 mm deep by 220 mm wide by 490 mm high, so verify desk space before ordering.
