More Information
Summary:The invention discloses a power detection method, and belongs to the technical field of servers, and the method comprises the steps: obtaining mainboard input power, actual mainboard power supply voltage, sampling resistance voltage difference, PSU input power and PSU output power under various loads, and determining more precise sampling resistance, voltage error and PSU conversion efficiency, compared with the prior art that the deviation value exceeds 35W or even more than 50W when the power consumption of a machine about 700W is limited in actual measurement, the actual measurement power deviation can be within 8W, the power detection accuracy is greatly improved under the condition that the cost is not increased, the power consumption limiting accuracy of the whole machine is improved, the requirement of customers for power consumption is better met, the product competitiveness is improved, and the application prospect is wide. And the problem of potential safety hazards of the rack or the machine room c
