2. Package Contents

Verify that all components are present in the package:

• Vertical GPU Card Holder Kit V3 (Black)
• PCIe 4.0 x16 Riser Cable (165mm)
• Mounting Screws (typically pre-attached or included for case mounting)

3. Setup and Installation

Before beginning installation, ensure your PC is powered off and unplugged from the wall outlet. It is recommended to wear an anti-static wrist strap to prevent damage to components.

3.1 Compatibility Check

• This kit is compatible with most E-ATX, ATX, and Micro-ATX cases.
• Ensure your case has at least 7 available PCIe expansion slots for standard ATX installation.
• For Micro-ATX cases, the removable bracket may be necessary. Be aware that removing this bracket might block a rear fan in some configurations.
• Verify that your GPU and CPU cooler combination allows sufficient clearance for vertical mounting.

3.2 Installation Steps

1. Prepare Your Case: Remove the existing PCIe slot covers from your PC case where the vertical GPU holder will be installed. For ATX cases, this typically involves removing all 7 expansion slot covers. For Micro-ATX cases, you may need to remove the dedicated M-ATX bracket from the holder first (refer to image below).

2. Mount the Holder: Position the vertical GPU holder inside your case, aligning its mounting holes with the screw holes on your case's PCIe expansion slot area. Secure the holder using the provided screws.

6. Connect Power and Display Cables: Connect the necessary PCIe power cables to your graphics card. Route your display cables (HDMI, DisplayPort) from the GPU to your monitor.

4. Operating Instructions

Once the Cooler Master Vertical GPU Holder Kit V3 is installed and your graphics card is securely mounted and connected, its operation is integrated with your PC's normal function. The holder itself is a passive component.

• Ensure all connections (motherboard, GPU, power, display) are firm before powering on your PC.
• After powering on, verify that your graphics card is detected by the system and functions correctly.
• Monitor GPU temperatures, especially in new configurations, to ensure adequate airflow. Adjust fan curves or case fan placement if necessary.

5. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your vertical GPU holder and associated components.

• Cleaning: Periodically clean the holder and riser cable to prevent dust buildup. Use compressed air or a soft, dry cloth. Ensure the PC is powered off and unplugged before cleaning.
• Connection Check: Every few months, gently check that the riser cable is securely seated in both the motherboard and GPU, and that the GPU is firmly attached to the holder.
• Physical Inspection: Inspect the holder and cable for any signs of wear, damage, or bending. The SGCC steel construction is designed for durability, but physical impacts can still cause damage.

6. Troubleshooting

If you encounter issues after installing the vertical GPU holder, consider the following troubleshooting steps:

• No Display/GPU Not Detected:
  • Ensure the PCIe riser cable is fully seated in both the motherboard's PCIe x16 slot and the GPU's PCIe slot.
  • Verify that all necessary PCIe power cables are connected to your graphics card.
  • Check your motherboard's BIOS/UEFI settings. Some motherboards may require setting the PCIe slot to a specific generation (e.g., PCIe Gen3 or Gen4) manually, especially if experiencing instability with Gen4.
  • Test the GPU directly in the motherboard's PCIe slot (without the riser cable) to rule out a GPU or motherboard issue.
• System Instability/Stuttering:
  • This can sometimes occur with PCIe riser cables if there's a compatibility issue or signal degradation. Try setting your motherboard's PCIe slot speed to Gen3 in the BIOS/UEFI. While the cable supports PCIe 4.0, some system configurations may be more stable at Gen3.
  • Ensure your motherboard BIOS is up to date.
• Physical Fitment Issues:
  • If the GPU is too close to the side panel or other components, utilize the toolless adjustment feature to move the holder horizontally (up to 65mm) or towards the motherboard (up to 30mm).
  • For Micro-ATX cases, confirm the M-ATX bracket has been removed if necessary.
  • Ensure your CPU cooler does not interfere with the vertically mounted GPU.
• GPU Sagging:
  • While the holder is reinforced, extremely heavy GPUs or specific case designs might still exhibit minor sag. Ensure all mounting screws are tightened. Consider additional GPU support brackets if persistent.
