Questions about this item

What does the 128 GB DDR5 mean for daily workstation workloads?

The system ships with 128 GB of DDR5 installed across the four DIMM slots on the PRIME X870-P motherboard, and the platform supports up to 192 GB if you add modules later.

What display outputs does the RTX A400 provide and how many monitors can it drive?

The RTX A400 includes four Mini DisplayPort connectors, so you can attach up to four displays directly from the graphics card.

Will the 240 mm liquid cooler and ATX motherboard fit in the Antec P10 FLUX case?

Yes — the case measures 477 × 220 × 486 mm, supports ATX motherboards and has mounting points for a 240 mm radiator, which matches the supplied Quiet Edition AIO cooler.
