Recently, I have joined in a company in server team. Now I am undergoing training in my company where my boss asked me to calculate computer power consumption for all individual desktop computers and laptops. As I am fresher in that company, I was confused and got frustrated in calculating power supply. I started surfing in online for about calculation. Now, I am happy to check this website about how to calculate Computer Power Supply from easycalculation.com. This calculation shows the power watts based on the various devices and its quantity. From knowing this calculation, I calculated the amount of power supply for all computers in my office. Thereby, I got credit from my boss and now I am happy to work over there with confidence
