Suits content creators

The 128GB DDR5 configuration and RTX 5090 with 32GB video memory support modelling, video editing, rendering and AI learning tasks. Buyers who need more than 192GB of total system memory or who require multiple graphics cards should look at a different platform.

128GB DDR5 memory installed across four slots

The motherboard provides four memory slots with a maximum supported capacity of 192GB. This build occupies all slots with 128GB of high-performance DDR5, leaving room for a future upgrade to the 192GB limit if the workload demands it.

Questions about this item

Will the 240 mm liquid cooler and 1200 W PSU fit in my existing case if I move the motherboard over?

The 240 mm AIO and 1200 W PSU are built into this system; moving the X870 motherboard to another case would require that case to support 240 mm radiator mounting and a standard ATX power supply.

How can I confirm the RTX 5090 is running at full PCIe x16 speed after I assemble the PC?

Open GPU-Z or the NVIDIA control panel and verify the bus interface reads PCIe x16 4.0 with no bandwidth reduction.

Which cables and accessories ship inside the box so I know what to buy separately?

The system arrives fully assembled with Windows 11 Pro installed, a power cord, and the motherboard driver disc; monitor cables, keyboard, mouse and any extra storage drives are not included.
