Intel Core i5-14600K on the ASUS ROG Maximus Z790 Hero
The Intel Core i5-14600K holds its clocks on the ASUS ROG Maximus Z790 Hero: the board's 20 Vcore stages carry about 1913 W and the processor asks for 180 W in a sustained all-core load, which is 9 % of capacity and an estimated 44 °C at the VRM.

What happens when you build this
There is real headroom here. The ASUS ROG Maximus Z790 Hero is rated for roughly 1913 W of continuous core power and the Intel Core i5-14600K draws 180 W once a ten-minute render settles, so the power stages spend their time well inside their comfortable range. An estimated 44 °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 — 20 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 Maximus Z790 Hero holds roughly 1913 W indefinitely. The Intel Core i5-14600K asks for 180 W of that, and at boost it can reach 181 W.
Buy it on the rest of the specification rather than on power delivery, because at 9 % 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 Maximus Z790 Hero's 20 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 is fed from the CPU, so installing a drive there splits the graphics lanes and the primary slot runs at x8.
Where the PCIe lanes go
The ASUS ROG Maximus Z790 Hero has 5 M.2 slots and one of them is wired to the processor rather than the chipset. The Gen 5 M.2 slot is fed from the CPU, so installing a drive there splits the graphics lanes and the primary slot runs at x8. 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 Maximus Z790 Hero takes DDR5, which the Intel Core i5-14600K supports, and validates memory up to DDR5-7800. Firmware is not an issue: the ASUS ROG Maximus Z790 Hero 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 ROG Maximus Z790 Hero?
No. The Intel Core i5-14600K draws 180 W in a sustained all-core load and the ASUS ROG Maximus Z790 Hero holds about 1913 W, so the VRM sits at an estimated 44 °C and clocks hold.
- How many power phases does the ASUS ROG Maximus Z790 Hero have?
20 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 Maximus Z790 Hero need a BIOS update for the Intel Core i5-14600K?
No. The ASUS ROG Maximus Z790 Hero 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 ROG Maximus Z790 Hero?
DDR5, in up to 4 slots, validated to DDR5-7800 on this board.
- What VRM temperature should I expect with the Intel Core i5-14600K on this board?
Our model estimates 44 °C, from 38 °C of interior case air plus the stress ratio of 0.09 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 Maximus Z790 Hero?
The Gen 5 M.2 slot is fed from the CPU, so installing a drive there splits the graphics lanes and the primary slot runs at x8.
