Modern business strongly relies on the use of information and communication technologies. So, choosing the right technical equipment is extremely important because the right one influences the timely execution of business tasks. Various conflicting criteria impact the decision about equipment selection which justifies the application of Multiple-Criteria Decision-Making (MCDM) as a convenient tool for the optimization of this kind of decision process. This paper proposes the application of the Preference Selection Index (PSI) method to settle the appropriate processing unit (CPU). Five alternative CPUs are compared against four criteria which include: core numbers, virtual cores (threads), operating frequency, and price. The results that came from using the PSI method favor the CPU3 - AMD Ryzen 5 5600 as the most compatible for the end-user in the present case. The obtained results proved the applicability of the PSI method because it facilitated the decision process and define the best solution regarding the given conditions.
