What is a Power Supply (PSU)?\u00a0\u00a0<\/h2>\n\n\n\n

Your power supply (PSU) plays a critical role in your gaming PC. It is responsible for supplying all your hardware with a steady and reliable flow of power. Without a PSU, your PC won\u2019t even be able to turn on.\u00a0\u00a0<\/p>\n<\/div>\n\n\n\n

Wattage\u00a0<\/h2>\n\n\n\n

Each PSU comes with a specific wattage which determines how much power it can deliver to your hardware. The higher the wattage is, the more power you achieve. <\/p>\n\n\n\n

When it comes to selecting the right PSU for your gaming PC, you first need to ensure it has a high enough wattage to power all your components at peak loads. We recommend you don\u2019t use a PSU that meets the bare minimum power requirements of your PC. Aim for something slightly higher to ensure you have all the power you need, along with leaving a little wiggle room in case of any unexpected power spikes during heavy loads. <\/p>\n\n\n\n

There are plenty of online PSU calculators<\/a> to help you to find out your PC\u2019s power requirement. Or better yet, we\u2019ve got a dedicated blog guide that takes you through how to do it.  <\/p>\n\n\n\n

80 PLUS Rating\u00a0<\/h2>\n\n\n\n

80 PLUS Rating <\/strong>is a phrase you\u2019ve definitely heard thrown about when it comes to power supplies. Keeping it simple, 80 PLUS Rating is a measure of PSU energy efficiency. At a minimum, a power supply needs to perform at 80% efficiency at 20%, 50%, and 100% loads.\u00a0\u00a0<\/p>\n\n\n\n
