Questions about this item

How loud and hot does the 240mm liquid cooler keep the 20-core Core Ultra 7 265K under all-day load?

The 240mm Quiet Edition AIO uses a 140mm low-noise fan and liquid cooling to manage the 20-core CPU at 3.7GHz base, up to 5.50GHz boost, with a 1000W 80 PLUS Gold PSU supplying efficient power.

What display cable and monitor port do I need for the RTX 5080 16GB to work out of the box?

The RTX 5080 16GB uses standard DisplayPort and HDMI outputs; connect a compatible monitor cable to one of those ports — no proprietary adapter is included.

Will my existing SATA SSDs and 2.5-inch drives fit inside the Antec P20 case alongside the 4TB NVMe boot drive?

Yes — the case provides two internal 3.5"/2.5" bays and two dedicated 2.5" bays, plus four SATA 6Gb/s ports on the Z890 motherboard for additional drives.
