Intel Core i9-14900K on the ASUS ROG Strix Z790-I Gaming WiFi
Pairing the Intel Core i9-14900K with the ASUS ROG Strix Z790-I Gaming WiFi puts 250 W through a 1116 W power stage array — 22 % of what the board holds — for an estimated VRM temperature of 52 °C and no measurable clock loss.

What happens when you build this
There is real headroom here. The ASUS ROG Strix Z790-I Gaming WiFi is rated for roughly 1116 W of continuous core power and the Intel Core i9-14900K draws 250 W once a ten-minute render settles, so the power stages spend their time well inside their comfortable range. An estimated 52 °C is the kind of VRM temperature that never appears in a log, and the board will not be the reason a benchmark run finishes slower than it started.
Counting only the stages that feed the core rail — 10 of them at 105 A, teamed in pairs off a shared controller channel — and derating for large finned blocks with real thermal mass, the ASUS ROG Strix Z790-I Gaming WiFi holds roughly 1116 W indefinitely. The Intel Core i9-14900K asks for 250 W of that, and at boost it can reach 253 W.
Buy it on the rest of the specification rather than on power delivery, because at 22 % 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 ROG Strix Z790-I Gaming WiFi's 10 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 ROG Strix Z790-I Gaming WiFi keeps its 2 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 ROG Strix Z790-I Gaming WiFi takes DDR5, which the Intel Core i9-14900K supports, and validates memory up to DDR5-7800. Firmware is not an issue: the ASUS ROG Strix Z790-I Gaming WiFi ships with a BIOS that already knows Raptor Lake Refresh.
Boards that run the Intel Core i9-14900K without throttling
Each of these keeps the processor under a third of the board's sustained power capacity, and each has a listing we can verify.

Questions people ask about this pairing
- Will the Intel Core i9-14900K throttle on the ASUS ROG Strix Z790-I Gaming WiFi?
No. The Intel Core i9-14900K draws 250 W in a sustained all-core load and the ASUS ROG Strix Z790-I Gaming WiFi holds about 1116 W, so the VRM sits at an estimated 52 °C and clocks hold.
- How many power phases does the ASUS ROG Strix Z790-I Gaming WiFi have?
10 Vcore power stages rated 105 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 ROG Strix Z790-I Gaming WiFi need a BIOS update for the Intel Core i9-14900K?
No. The ASUS ROG Strix Z790-I Gaming WiFi ships with a BIOS that already supports Raptor Lake Refresh, so the Intel Core i9-14900K posts out of the box.
- What memory does the Intel Core i9-14900K take on the ASUS ROG Strix Z790-I Gaming WiFi?
DDR5, in up to 2 slots, validated to DDR5-7800 on this board.
- What VRM temperature should I expect with the Intel Core i9-14900K on this board?
Our model estimates 52 °C, from 38 °C of interior case air plus the stress ratio of 0.22 scaled by 65 °C. Measured numbers move with case airflow and ambient temperature, so treat this as a band rather than a reading.
