Intel Core Ultra 5 245K on the ASUS Prime B860-Plus WiFi

Pairing the Intel Core Ultra 5 245K with the ASUS Prime B860-Plus WiFi puts 155 W through a 476 W power stage array — 33 % of what the board holds — for an estimated VRM temperature of 59 °C and no measurable clock loss.

There is a full write-up for this pairing once it reaches the publication queue. Until then, everything the engine knows about it is on this page.

Peak boost: Peak boost 59 °C

Power delivery

Each bar is one Vcore power stage, filled to the share of its capacity this processor asks for. The dashed line is the 85 % mark where our model starts predicting clock loss.

There is real headroom here. The ASUS Prime B860-Plus WiFi is rated for roughly 476 W of continuous core power and the Intel Core Ultra 5 245K draws 155 W once a ten-minute render settles, so the power stages spend their time well inside their comfortable range. An estimated 59 °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 — 8 of them at 80 A, teamed in pairs off a shared controller channel — and derating for a thin heatsink that helps at idle more than under load, the ASUS Prime B860-Plus WiFi holds roughly 476 W indefinitely. The Intel Core Ultra 5 245K asks for 155 W of that, and at boost it can reach 159 W.

Buy it on the rest of the specification rather than on power delivery, because at 33 % 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 B860-Plus WiFi's 8 stages get on with it.
