## Abstract

A control method, system and device for a power consumption upper limit of a server, and a readable storage medium, includes: determining, according to a server policy, a power consumption upper limit of a management engine (ME) to be a first expected upper limit; acquiring actual power consumption of a server; comparing the current actual power consumption with the first expected upper limit and a second expected upper limit; and if the current actual power consumption is greater than the first expected upper limit and does not exceed the second expected upper limit, lowering a current power consumption upper limit until the current actual power consumption is lowered such that same does not exceed the first expected upper limit.
