Intel Core i5-14600K on the ASUS Prime Z790-A WiFi
On the ASUS Prime Z790-A WiFi, the Intel Core i5-14600K runs at 20 % of the board's 918 W sustained power capacity, which puts the VRM at an estimated 51 °C and leaves clocks untouched.

What happens when you build this
This pairing is not close to any limit. 180 W against 918 W of capacity leaves the ASUS Prime Z790-A WiFi running its stages at 20 % load, and our model puts the VRM at 51 °C in a closed case. Nothing about the Intel Core i5-14600K pushes this board into the region where clocks start dropping.
The ASUS Prime Z790-A WiFi carries 16 Vcore power stages rated 60 A each, teamed in pairs off a shared controller channel, with a solid block across both banks. That works out to about 918 W of sustained core power once the design and the cooling are accounted for, which is the number the Intel Core i5-14600K's 180 W is measured against.
Buy it on the rest of the specification rather than on power delivery, because at 20 % 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 Z790-A 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.

Power delivery
Where the PCIe lanes go
The ASUS Prime Z790-A 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 Z790-A WiFi takes DDR5, which the Intel Core i5-14600K supports, and validates memory up to DDR5-7600. Firmware is not an issue: the ASUS Prime Z790-A WiFi ships with a BIOS that already knows Raptor Lake Refresh.

Questions people ask about this pairing
- Will the Intel Core i5-14600K throttle on the ASUS Prime Z790-A WiFi?
No. The Intel Core i5-14600K draws 180 W in a sustained all-core load and the ASUS Prime Z790-A WiFi holds about 918 W, so the VRM sits at an estimated 51 °C and clocks hold.
- How many power phases does the ASUS Prime Z790-A WiFi have?
16 Vcore power stages rated 60 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 Z790-A WiFi need a BIOS update for the Intel Core i5-14600K?
No. The ASUS Prime Z790-A WiFi ships with a BIOS that already supports Raptor Lake Refresh, so the Intel Core i5-14600K posts out of the box.
- What memory does the Intel Core i5-14600K take on the ASUS Prime Z790-A WiFi?
DDR5, in up to 4 slots, validated to DDR5-7600 on this board.
- What VRM temperature should I expect with the Intel Core i5-14600K on this board?
Our model estimates 51 °C, from 38 °C of interior case air plus the stress ratio of 0.20 scaled by 65 °C. Measured numbers move with case airflow and ambient temperature, so treat this as a band rather than a reading.
