  • CPU energy connector: Provides energy to the processor. You would possibly want 2x 8-pin connectors, so examine your motherboard.
  • PCIe energy connectors: Provides energy to the graphics card. Depending on the mannequin and make of your GPU, you’ll need to use a sure variety of 6- or 8-pin energy connectors.
  • Peripheral energy connectors (MOLEX and SATA): These connectors are used on your storage drives similar to a SATA HDD or SSD. Also, it powers different peripherals similar to your case followers, RGB lighting, and extra. It is usually beneficial to plug in no less than one SATA energy connector, however for those who plan on utilizing a number of HDDs/ SSDs and different peripherals, you might want two connectors. We recommend you seek the advice of the documentation on your energy provide and different elements to decide the variety of connectors wanted.

Note: If you will have a non-modular PSU, you might proceed with the set up information and never use the additional cables that aren’t required to energy any elements.

How to Install Power Supply (PSU) in PC Case

1. Once you might be prepared along with your energy provide and the set up instruments, step one requires you to work out the place to set up the PSU. In most PC circumstances nowadays, the ability provide shroud a few PC circumstances, the ability provide shroud is normally positioned on the backside, whereas in some circumstances, it’s positioned on the high. You additionally want to guarantee the ability provide fan has correct air flow in its last orientation.

2. Now, place the ability provide in its designated location, ensuring the ability provide fan aligns with the air flow cutout in the case. In most situations, you will have to merely place the PSU with its fan dealing with downwards.

Note: The PSU fan should align with the air flow holes current in your case. If the fan is blocked when dealing with downwards, you want to change the ability provide orientation to make sure the fan can cool the unit correctly.
