Is this EZDIY-FAB GPU extension cable safe for my PC?

Yes, the EZDIY-FAB 12VHPWR PCIe 5.0 extension cable is designed for safe and stable power delivery up to 600W, using 16AWG tinned copper and alloy copper terminals. It connects your compatible high-end GPU to your PSU's PCIe 8-pin cables, preventing issues like frame drops. Ensure you use a PSU of 1000W or more and connect it correctly as an extension, not directly to the PSU.

What wattage power supply do I need for my PC?

Add up the peak draw of your CPU and GPU, then add roughly 20–30% headroom for spikes and future upgrades. A mid-range gaming build with a single GPU commonly pairs well with a 650W–750W unit, while high-end multi-component systems may need 850W or more. This extension cable supports up to 600W, and a 1000W+ PSU is generally recommended for the GPUs it's designed for.

Will this power supply cable work with Indian mains electricity?

This is a power cable extension for your PC's internal components and does not connect directly to mains electricity. It draws power from your PC's power supply unit (PSU). Ensure your PSU is compatible with Indian voltage (230V, 50Hz) and has the necessary PCIe 8-pin outputs to connect to this extension cable.

How to choose the right GPU extension cable?

Ensure the cable matches your GPU's connector type (e.g., 12VHPWR 16pin for RTX 40 Series) and your PSU's available outputs (e.g., PCIe 8-pin). Check the cable's wattage rating and material quality (like 16AWG copper) for stability. Consider length and aesthetics, including cable combs for management. This EZDIY-FAB cable is ideal for RTX 4080/3090 Ti with a 12VHPWR connector.

Can I use this GPU extension cable with my RTX 3070?

No, this EZDIY-FAB GPU extension cable is specifically designed for the 12VHPWR (16pin, 12+4) connector found on RTX 40 Series and RTX 3090 Ti GPUs. It is not suitable for older 12pin GeForce RTX 30 Series GPUs. Please check your GPU's specific power connector requirements before purchasing.

What is the best GPU extension cable for a clean PC build?

For a clean PC build, look for sleeved extension cables with integrated cable combs, like the EZDIY-FAB Black 12VHPWR cable. Its black sleeving and included combs help organize cables, reducing clutter and improving airflow. This ensures a professional and tidy appearance for your high-performance gaming or workstation setup.

What is the warranty for this GPU extension cable in India?

This EZDIY-FAB GPU extension cable is sourced from authorized US retailers and authorized brand partners and imported for you. It comes with the standard manufacturer's warranty from EZDIY-FAB. For any issues related to manufacturing defects or damage during transit, CrowCrowcrow offers a 14-Day Smile Guarantee for returns or replacements.
