Proper thermal management and derating can also extend the life of both the power supply and the equipment it powers.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"FAQs\"><\/span><strong>SSS<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>What&#8217;s the difference between AC and DC?<\/strong><\/p>\n<p><b><span class=\"citation-13\">AC (Alternating Current)<\/span><\/b><span class=\"citation-13 citation-end-13\"> is the type of electricity you get from a wall outlet.<\/span> Its direction of flow changes constantly. <b><span class=\"citation-12\">DC (Direct Current)<\/span><\/b><span class=\"citation-12 citation-end-12\"> flows in a single, constant direction and is what most electronic components, like microchips and batteries, need to operate.<\/span> An AC-DC power supply converts one into the other.<\/p>\n<p><strong>How do I calculate my power needs?<\/strong><\/p>\n<p><span class=\"citation-11\">To calculate your total power need, multiply the voltage (V) by the current (A) of your circuit: <\/span><b><span class=\"citation-11\">Power (Watts) = Volts \u00d7 Amps<\/span><\/b><span class=\"citation-11 citation-end-11\">.<\/span> It&#8217;s always a good idea to add a <b>20-30% safety margin<\/b> to your calculation to account for future expansion or unexpected power spikes.<\/p>\n<p><strong>Why is a power supply&#8217;s efficiency important?<\/strong><\/p>\n<p>A power supply&#8217;s efficiency rating tells you how much of the input power is converted into usable output power, with the rest being wasted as heat. A higher efficiency rating means less energy is wasted, which translates to lower electricity bills and less heat generated.
