The Gigabyte Z790 AORUS motherboard provides four DDR5 slots supporting up to 192GB total and four M.2 connectors alongside six SATA ports. The Antec P20 mid-tower case offers two 3.5-inch bays and two 2.5-inch bays with dust filters on three sides. Front-panel I/O includes USB 3.2 Gen 2 Type-C and two USB 3.0 ports for peripheral access.

Questions about this item

How long can the 360mm liquid cooler keep the 24-core i9-14900K at full speed before it hits thermal limits?

The 360mm Quiet Edition AIO is designed to handle the i9-14900K's 24 cores and 32 threads under sustained loads, with the large radiator surface area and high-static-pressure fans moving heat away from the CPU continuously.

What noise level and heat output should I expect from the 850W PSU and liquid cooler during an all-day render?

The Thermaltake Smart 850W 80 PLUS Bronze unit uses a 140mm ultra-quiet fan and Japanese capacitors, while the 360mm AIO runs low-noise 120mm fans, keeping acoustic output low even when the system draws high power for hours.

Does the RTX A400 require any special cables or adapters to run four Mini DisplayPort monitors?

The RTX A400 includes four native Mini DisplayPort outputs, so you only need standard Mini DisplayPort cables or Mini DisplayPort-to-DisplayPort adapters for each monitor — no extra power cables or active converters are required.
