Processor and graphics power

The Thermaltake Reactor u2880S is a white gaming desktop built around an Intel Core Ultra 9 285K 24-core processor and an NVIDIA GeForce RTX 5080 graphics card with 16 GB GDDR7 memory. It includes 32 GB DDR5 memory, a 2 TB NVMe SSD and a 1000 W 80Plus Gold ATX 3.0 power supply. A 360 mm ARGB AIO cooler and Windows 11 Home complete the system.

Buyers who need more memory or storage upfront

This configuration suits players and creators who want a ready-to-run platform with current-generation CPU and GPU performance. The 32 GB DDR5 and 2 TB NVMe drive cover most modern titles and workloads without immediate upgrades. Buyers who need more memory or storage upfront should look at systems offering larger capacities.

The RTX 5080 with 16 GB GDDR7

The single specification that decides fit is the RTX 5080 with 16 GB GDDR7. It determines the level of gaming and creative performance available from this desktop. If that GPU tier matches the target resolution and workload, the Reactor u2880S delivers a balanced, pre-built solution.

Questions about this item

What case clearance does the 360mm ARGB AIO radiator need?

The 360mm radiator requires a case with a 360mm mounting location and enough clearance for the fans on each side.

How is the Thermaltake 360mm ARGB AIO installed, and what step is often missed?

The AIO comes pre-installed on the Intel Core Ultra 9 285K; the step often missed is connecting the pump header and ARGB cable to the Z890 motherboard before first boot.

What maintenance will the 360mm ARGB AIO liquid cooler need later?

The sealed 360mm AIO is maintenance-free for its lifespan; only the radiator fins and three fans need periodic dust cleaning.
