  2. Aligning the Card: Carefully align the new graphics card with the PCIe slot. Make sure the faceplate is lined up with the back panel slots.
  3. Securing the Card: Once the card is aligned, gently press it into the slot. You should hear a click as the card’s connector seats securely in the PCIe slot.
  4. Screwing in the Card: Use the screws you removed from the old card to secure the new card to the case. This prevents any movement or sagging of the card.
  5. Connecting Power Supply (if Required): If your new graphics card has power connectors, plug in the PCIe power cables from your power supply unit. These can be 6-pin or 8-pin connectors, depending on the card.

Ensuring Proper Seating and Connection to the Motherboard

After installing the card, double-check that it is seated properly. A properly installed card will sit evenly in the slot without any angle or wiggle.

The faceplate should be flush with the back panel of the case. If the card is not seated correctly, it may not function properly or could cause damage to the motherboard.

Connecting Power Supply to the Graphics Card (if Applicable)

For graphics cards requiring additional power, ensuring a secure connection with the power supply is crucial. Incorrect or loose connections can lead to power issues or even hardware damage.

Match the power connectors to the ports on the graphics card and plug them in firmly but gently.
