Intel Core i9-13900K on the ASUS ROG Strix Z790-F Gaming WiFi
Pairing the Intel Core i9-13900K with the ASUS ROG Strix Z790-F Gaming WiFi puts 250 W through a 1530 W power stage array — 16 % of what the board holds — for an estimated VRM temperature of 48 °C and no measurable clock loss.

What happens when you build this
There is real headroom here. The ASUS ROG Strix Z790-F Gaming WiFi is rated for roughly 1530 W of continuous core power and the Intel Core i9-13900K draws 250 W once a ten-minute render settles, so the power stages spend their time well inside their comfortable range. An estimated 48 °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 — 16 of them at 90 A, teamed in pairs off a shared controller channel — and derating for large finned blocks with real thermal mass, the ASUS ROG Strix Z790-F Gaming WiFi holds roughly 1530 W indefinitely. The Intel Core i9-13900K 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 16 % 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-F Gaming WiFi's 16 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.

What else to know about this pairing
Note: One M.2 slot borrows lanes from the graphics slot
The Gen 5 M.2 slot borrows four graphics lanes, leaving the primary slot at x8 when it is used.
Where the PCIe lanes go
The ASUS ROG Strix Z790-F Gaming WiFi has 4 M.2 slots and one of them is wired to the processor rather than the chipset. The Gen 5 M.2 slot borrows four graphics lanes, leaving the primary slot at x8 when it is used. A current graphics card loses one or two percent from that, which matters far less than most forum threads suggest — but it is worth knowing before you wonder why your card reports x8.
The ASUS ROG Strix Z790-F Gaming WiFi takes DDR5, which the Intel Core i9-13900K supports, and validates memory up to DDR5-7800. Firmware is not an issue: the ASUS ROG Strix Z790-F Gaming WiFi ships with a BIOS that already knows Raptor Lake.

Questions people ask about this pairing
- Will the Intel Core i9-13900K throttle on the ASUS ROG Strix Z790-F Gaming WiFi?
No. The Intel Core i9-13900K draws 250 W in a sustained all-core load and the ASUS ROG Strix Z790-F Gaming WiFi holds about 1530 W, so the VRM sits at an estimated 48 °C and clocks hold.
- How many power phases does the ASUS ROG Strix Z790-F Gaming WiFi have?
16 Vcore power stages rated 90 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-F Gaming WiFi need a BIOS update for the Intel Core i9-13900K?
No. The ASUS ROG Strix Z790-F Gaming WiFi ships with a BIOS that already supports Raptor Lake, so the Intel Core i9-13900K posts out of the box.
- What memory does the Intel Core i9-13900K take on the ASUS ROG Strix Z790-F Gaming WiFi?
DDR5, in up to 4 slots, validated to DDR5-7800 on this board.
- What VRM temperature should I expect with the Intel Core i9-13900K on this board?
Our model estimates 48 °C, from 38 °C of interior case air plus the stress ratio of 0.16 scaled by 65 °C. Measured numbers move with case airflow and ambient temperature, so treat this as a band rather than a reading.
- Does an M.2 drive affect the graphics slot on the ASUS ROG Strix Z790-F Gaming WiFi?
The Gen 5 M.2 slot borrows four graphics lanes, leaving the primary slot at x8 when it is used.
