Do GPUs Come with Power Cables?

In most cases, GPUs do not come with power cables. The primary reason for this is that power cables are usually supplied by the power supply unit (PSU) rather than the GPU manufacturer. PSUs come with various power cables, including PCIe power connectors, which are used to connect the GPU to the PSU.

Why Don’t GPUs Include Power Cables?

Standardization: 

Power cables that connect the GPU to the PSU are standardized, meaning they are universally compatible with different brands and models of GPUs. As a result, there’s no need for GPU manufacturers to include them in the packaging.

PSU Responsibility: 

The power supply unit (PSU) is responsible for providing the necessary connectors for all internal components, including the GPU. Since PSUs come with these cables, adding them to the GPU packaging would be redundant.

Cost Consideration:

Including power cables in GPU packaging would increase manufacturing costs, which would likely be passed on to the consumer. By not including them, manufacturers can keep costs down.

What Are GPU Power Cables?

GPU power cables, also known as PCIe cables, are essential for supplying electrical power to a Graphics Processing Unit (GPU) within a computer system.

These cables connect the GPU to the power supply unit (PSU), ensuring it receives the necessary power for optimal performance.

Modern GPUs, particularly high-performance models used for gaming or professional graphics work, often need more power than what the motherboard can provide through PCIe slots alone.

To meet these power demands, GPUs typically include one or more power connectors.

Types of GPU Power Cables

6-Pin Power Connectors:

Motherboards typically deliver up to 75 watts of power to GPUs via the PCI Express x16 slot. However, most GPUs require more power than this.

The 6-pin power connector provides an additional 75 watts, combined with the motherboard’s power to offer a total of up to 150 watts. 

This type of connector is usually sufficient for mid- and entry-level graphics cards, especially older models. Advanced GPUs, however, may need more than one 6-pin connector.

6+2 Pin Power Connectors:

The 6+2 pin power connector design has become increasingly popular due to its flexibility. These connectors can function as either a 6-pin or an 8-pin connector.

This adaptability allows PSU manufacturers to support various GPU requirements with a single connector type. 

A 6+2 connector can deliver 75 watts with the 6-pin and up to 150 watts with the full 8 pins.

8-Pin Power Connectors:

8-pin power connectors are becoming more common due to the higher power demands of modern GPUs. They provide 150 watts of power, which, combined with the 75 watts from the PCIe slot, totals 225 watts. 

These connectors are suitable for newer mid-range GPUs. Some graphics cards may require more than one 8-pin connector, with certain high-performance models needing up to 300 watts from a combination of 6-pin and 8-pin connectors. 

Occasionally, high-end GPUs may use a triple 8-pin setup, reserved for the most demanding applications.

12-Pin Power Connectors:

Introduced by Nvidia with their GeForce RTX 3000 (Ampere) series in 2020, the 12-pin power connector offers up to 504 watts of power, making it ideal for high-end GPUs. Despite being the same width as the 8-pin connectors, the pins are slightly smaller. 

To ensure compatibility with existing power supplies, adapters are available to convert 12-pin connectors to dual 8-pin connections.

16-Pin Power Connectors:

The 16-pin connector, also known as the 12+4 pin connector, debuted with the Nvidia 4000 series Founders Edition GPUs. It supports significant power delivery but is only compatible with Gen-5 / ATX 3.0 PSUs. 

Users with older PCI Gen-4 / ATX 2.0 PSUs will need an 8-pin to 16-pin 600-watt 12VHPWR adapter to use these GPUs.

What to Consider When Selecting GPU Power Cables in 2024?

Modularity:

Some power supplies feature modular cables, which allow users to connect only the cables they need and leave out the rest.

This modular design is particularly beneficial for GPU power cables as it helps reduce clutter inside the computer case, improving airflow and simplifying cable management. 

When offering modular GPU power cables, ensure they are compatible with the target consumer’s modular PSU interface to guarantee a secure and reliable connection between the power supply unit and the graphics card.

Cable Length:

The length of GPU power cables is crucial, especially for larger cases. Cables should be long enough to comfortably reach from the PSU to the GPU without causing slack or tension. Businesses should consider the size and layout of their target consumers’ cases when selecting cable lengths. Common lengths include:

• 400 to 450 mm: Suitable for small form factor (SFF) cases, prioritizing flexibility and cable management.
• 500 to 550 mm: Ideal for mid-tower cases, which is a common length that fits most setups.
• 600 to 650 mm: Best for full-tower cases with longer cable runs.
• 700+ mm: Designed for extra-large cases and vertical GPU mounting, addressing specialized scenarios with extended cable needs.

Gauge and Material:

The wire gauge and materials used in GPU power cables impact their performance and efficiency. A lower gauge number indicates thicker wires that can carry more current, making them better suited for high-end, power-hungry GPUs. Here’s a breakdown of the common wire gauges.

• 18 AWG: Supports up to 300W, suitable for most mainstream GPUs and entry-level high-performance cards.
• 16 AWG: Handles up to 450W, used for mid-range high-performance GPUs and some high-end cards.
• 14 AWG: Supports up to 600W, ideal for high-end and enthusiast GPUs with high power demands.
• 12 AWG: Handles 800W+, used for extreme overclocking and high-end GPUs with very high power requirements.

High-quality materials, such as copper, and good construction can minimize resistance and improve power delivery, reducing the risk of voltage drops and electrical issues. Opt for GPU power cables made from top-notch materials for better performance.

Rounding Up:

The number of power cables needed varies by GPU model. At a minimum, a single 6-pin power connector is required. Mid-range GPUs generally need either dual 6-pin connectors or a single 8-pin connector, delivering around 150W of power. 

Higher-end GPUs may require additional cables, potentially up to triple 8-pin setups. While some GPUs do not require extra power cables, many do. Use these guidelines to ensure consumers have the right GPU power cables for their PC-building needs.
