Intel Core Ultra 7 265K on the ASUS Prime Z890-P WiFi
On the ASUS Prime Z890-P WiFi, the Intel Core Ultra 7 265K runs at 21 % of the board's 1071 W sustained power capacity, which puts the VRM at an estimated 52 °C and leaves clocks untouched.

What happens when you build this
This pairing is not close to any limit. 230 W against 1071 W of capacity leaves the ASUS Prime Z890-P WiFi running its stages at 21 % load, and our model puts the VRM at 52 °C in a closed case. Nothing about the Intel Core Ultra 7 265K pushes this board into the region where clocks start dropping.
The ASUS Prime Z890-P WiFi carries 14 Vcore power stages rated 80 A each, teamed in pairs off a shared controller channel, with a solid block across both banks. That works out to about 1071 W of sustained core power once the design and the cooling are accounted for, which is the number the Intel Core Ultra 7 265K's 230 W is measured against.
Buy it on the rest of the specification rather than on power delivery, because at 21 % of capacity the VRM has stopped being the interesting variable. Count the M.2 slots you need, check the rear ports against what you actually plug in, and let the ASUS Prime Z890-P WiFi's 14 stages get on with it.
The measurement
The gauge shows the estimated VRM temperature under a sustained all-core load, with a thinner copper needle for the brief peak the processor reaches at full boost. The schematic beside it shows the same thing as current per power stage.

Power delivery
Where the PCIe lanes go
The ASUS Prime Z890-P WiFi keeps its 4 M.2 slots clear of the graphics lanes, so the primary slot stays at x16 whatever you install. That is one fewer configuration trap than boards that route a second M.2 slot from the processor.
The ASUS Prime Z890-P WiFi takes DDR5, which the Intel Core Ultra 7 265K supports, and validates memory up to DDR5-8600. Firmware is not an issue: the ASUS Prime Z890-P WiFi ships with a BIOS that already knows Arrow Lake.

Questions people ask about this pairing
- Will the Intel Core Ultra 7 265K throttle on the ASUS Prime Z890-P WiFi?
No. The Intel Core Ultra 7 265K draws 230 W in a sustained all-core load and the ASUS Prime Z890-P WiFi holds about 1071 W, so the VRM sits at an estimated 52 °C and clocks hold.
- How many power phases does the ASUS Prime Z890-P WiFi have?
14 Vcore power stages rated 80 A each, in a teamed design. Counting only the core rail matters here — vendor marketing often adds the SoC and auxiliary phases to reach a bigger number, and those carry none of the CPU's core load.
- Does the ASUS Prime Z890-P WiFi need a BIOS update for the Intel Core Ultra 7 265K?
No. The ASUS Prime Z890-P WiFi ships with a BIOS that already supports Arrow Lake, so the Intel Core Ultra 7 265K posts out of the box.
- What memory does the Intel Core Ultra 7 265K take on the ASUS Prime Z890-P WiFi?
DDR5, in up to 4 slots, validated to DDR5-8600 on this board.
- What VRM temperature should I expect with the Intel Core Ultra 7 265K on this board?
Our model estimates 52 °C, from 38 °C of interior case air plus the stress ratio of 0.21 scaled by 65 °C. Measured numbers move with case airflow and ambient temperature, so treat this as a band rather than a reading.
