Questions about this item

How much RAM can the motherboard support before I hit the ceiling?

The Z790 PRIME board accepts up to 192 GB of DDR5 across its four slots, so the installed 64 GB leaves room for three more modules.

What noise and heat should I expect from the 360 mm liquid cooler and 1200 W Gold PSU during all-day loads?

The 360 mm Quiet Edition AIO and the PSU’s 140 mm ultra-quiet fan are both designed for low noise, while the Gold-rated 1200 W supply keeps waste heat down under sustained draw.

Which display cables must I already own to connect the RTX 5090?

The RTX 5090 uses standard DisplayPort and HDMI outputs, so have the matching cables for your monitor ready before the system arrives.
