Reactor 7870TH Gaming Desktop

The Thermaltake Reactor 7870TH is a pre-built gaming desktop aimed at enthusiasts who want a ready-to-play system. It ships with Windows 11 Home installed and carries the AI Ready designation. Buyers who prefer to select every component themselves or need a workstation-class platform should look elsewhere.

32 GB DDR5 6400 and 2 TB NVMe

The system includes 32 GB of DDR5 memory running at 6400 MT/s, with the motherboard supporting up to 128 GB for future expansion. A 2 TB NVMe solid-state drive provides the primary storage; there is no mechanical hard drive included. Users planning large media libraries or extensive game collections will need to add secondary storage.

B850 Chipset with 850 W Power and 240 mm AIO

Built on an AMD B850 chipset, the platform pairs the Ryzen 7 7800X3D with an 850 W power supply and a 240 mm ARGB all-in-one liquid cooler. Connectivity covers Gigabit Ethernet, Wi-Fi 6 and Bluetooth 5.3, while audio outputs 7.1 channels. Builders requiring additional PCIe lanes or a larger radiator mount will need a different chassis.

Questions about this item

Will the AMD B850 motherboard support my existing AM4 cooler mounting hardware?

The motherboard uses the AM5 socket so AM4 mounting brackets will not fit; the system ships with a Thermaltake 240mm ARGB AIO cooler that includes the correct AM5 hardware.

How can I verify the RTX 5070 Ti is running at full 16 GB GDDR7 capacity after setup?

Open Task Manager or GPU-Z and confirm the graphics card shows 16 GB dedicated video memory and the GDDR7 memory type.

What components are included in the box and what must be purchased separately?

The box contains the complete desktop with Ryzen 7 7800X3D, 32GB DDR5 6400 memory, 2TB NVMe SSD, RTX 5070 Ti 16 GB GDDR7, 850W power supply, 240mm ARGB AIO cooler, Wi-Fi 6, Bluetooth 5.3, Gigabit Ethernet, 7.1-channel audio and Windows 11 Home; only a monitor, keyboard and mouse need to be added.
