Intel Core i9-14900K on the ASUS Prime B760M-A WiFi D4
The Intel Core i9-14900K loses a little speed under sustained load on the ASUS Prime B760M-A WiFi D4: the board's 8 Vcore stages carry about 298 W and the processor asks for 250 W in a sustained all-core load, which is 84 % of capacity and an estimated 93 °C at the VRM.

What happens when you build this
Expect a small, measurable loss. Running 250 W through 298 W of capacity leaves the ASUS Prime B760M-A WiFi D4 at 84 % load, which our model turns into 93 °C at the VRM and about 5 % off sustained clocks for the Intel Core i9-14900K. It is a usable build, but the board is the part holding it back.
The ASUS Prime B760M-A WiFi D4 carries 8 Vcore power stages rated 50 A each, teamed in pairs off a shared controller channel, with a thin heatsink that helps at idle more than under load. That works out to about 298 W of sustained core power once the design and the cooling are accounted for, which is the number the Intel Core i9-14900K's 250 W is measured against.
You can build this. If the machine mostly games, the 5 % our model expects will not show up in a frame-rate graph, because games rarely hold all cores at full power long enough to matter. If it renders, compiles or encodes for more than a few minutes at a time, the next board up recovers that 5 % for less than the price of the Intel Core i9-14900K's next model up.
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
What else to know about this pairing
Note: PCIe 5.0 from the CPU runs at 4.0 speeds here
The Intel Core i9-14900K provides PCIe 5.0 lanes but the ASUS Prime B760M-A WiFi D4 wires its slots for PCIe 4.0. Nothing stops working; a Gen 5 SSD simply runs at Gen 4 speed, which no game notices.
Where the PCIe lanes go
The ASUS Prime B760M-A WiFi D4 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 Prime B760M-A WiFi D4 takes DDR4, which the Intel Core i9-14900K supports, and validates memory up to DDR4-5333. Firmware is not an issue: the ASUS Prime B760M-A WiFi D4 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 Prime B760M-A WiFi D4?
Yes, by about 5 % of sustained all-core clock speed. The Intel Core i9-14900K asks for 250 W and the ASUS Prime B760M-A WiFi D4 carries roughly 298 W, which puts its power stages at an estimated 93 °C.
- How many power phases does the ASUS Prime B760M-A WiFi D4 have?
8 Vcore power stages rated 50 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 B760M-A WiFi D4 need a BIOS update for the Intel Core i9-14900K?
No. The ASUS Prime B760M-A WiFi D4 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 Prime B760M-A WiFi D4?
DDR4, in up to 4 slots, validated to DDR4-5333 on this board.
- What VRM temperature should I expect with the Intel Core i9-14900K on this board?
Our model estimates 93 °C, from 38 °C of interior case air plus the stress ratio of 0.84 scaled by 65 °C. Measured numbers move with case airflow and ambient temperature, so treat this as a band rather than a reading.
