How do you have to install a power supply? An instruction

Since the power supply has important functions to perform, you should install it as optimally as possible. You can read about the best way to attach the power supply around in this practical tip.

Install the power supply with the fan facing down into the computer

Opinions differ as to how the power supply should be installed in the computer. Basically, the fan should transport cool air from outside into the heated interior of the computer and expel the hot air from the computer backwards.

• The computer's power supply is usually located in the lower area of ​​the housing. In order to protect the inside of the PC from dirt, the opening is often provided with an appropriate dust protection.
• Place your computer so that the fan can draw fresh and, above all, cool air from below. You can set up or hang the computer up a bit, for example with a special PC holder.
• The advantage of this variant is that the cool air from the outside cools the interior accordingly. The power supply also usually runs quieter because it also does not heat up as quickly.

Install the power supply with the fan towards the interior

If you install the power supply with the fan towards the interior of the computer, this variant also has one or two advantages.

• On the one hand, less dirt gets into the interior of the computer through the fan.
• On the other hand, the graphics card is usually cooled much better, which is a clear advantage, especially with gaming PCs.
• However, since significantly less cool air gets into the computer overall, the power supply, among other things, heats up faster and your computer becomes significantly louder, which is not a real pleasure depending on the power supply.
