Built for Workstation and Gaming Demands

This desktop combines a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5090 graphics card. It includes 32GB of DDR5 memory and an 8TB NVMe SSD array. The system ships with Windows 11 Pro installed in a liquid-cooled tower chassis.

Moving From Air Cooling or Smaller Storage

The 240mm liquid cooler handles sustained workloads better than standard air coolers on high-core-count CPUs. Dual 4TB NVMe drives replace smaller single-drive setups, removing the need to juggle projects across volumes. The jump is worth it when render queues or texture streaming exceed air-cooled thermal limits or 2TB capacity.

PCIe 4.0 and 1200W Define the Ceiling

The motherboard and SSD array operate at PCIe 4.0 speeds, so sequential transfers peak at the drive ratings of 7450 MB/s read and 6900 MB/s write. The 1200W 80 PLUS Gold power supply sets the total system power envelope. Memory expansion stops at 192GB across four slots.

商品問答

What clearance does the Antec P20 case need for the 240 mm liquid cooler radiator?

The 240 mm radiator mounts in the front of the Antec P20 case, which measures 469 mm deep by 220 mm wide by 490 mm high, so ensure your desk space accommodates those dimensions.

Which motherboard power connectors must be seated for the Ryzen 9 9900X3D on the PRIME X870-P board?

Connect the 24-pin ATX cable and the 8-pin EPS CPU cable from the Thermaltake Toughpower 1200W PSU; the EPS connector is often missed during first builds.

How many M.2 slots remain free for future SSD upgrades after the two 4 TB Samsung 990 PRO drives are installed?

The PRIME X870-P provides four M.2 connectors; two are occupied by the factory 4 TB drives, leaving two open slots for additional NVMe storage.
