In recent years we are seeing how graphics cards are easily the component that is demanding the most from current power supplies. If a decade ago a 750 W source could supply your computer with plenty, with which are expected to arrive this year said power supply becomes obsolete. First because of the power, and then because standardized power cords are falling short, and a new standard must be made.
Multiple cables from a single power supply can be connected to a GPU. But we must bear in mind that we are handling material that costs thousands of euros in total, and we must know how to use it. So, before you build your dream PC with one of the new graphics cards coming out this year, here's the caution of using Antec's PCI-E power supplies.
Antec does not teach how to connect multiple PCie cables to a single graphic
The PCI-E header supplies power to the GPU. a single wire usually contains 2 headers of 6+2 pins. Lately, the power consumption of high-end GPUs is increasing. Therefore, Antec recommends that if the GPU model requires 200W or more, 2 or 3 6+2pin headers are used to power the GPU.
The PCI-E header supplies power to the GPU. A single cable usually contains 2 headers of 6+2pins. Lately, the power consumption of high-end GPUs is increasing. Therefore, it is highly recommended that if the GPU model requires 200W or more, we use 2 or 3 6+2pin headers to power the GPU as shown below.
We are advised that if the GPU contains two headers, use 2 PCI-E cables to power each 6+2pin header. But if the GPU contains three heads, regardless of whether it can be supplied with power with less, they suggest using 3 PCI-E cables to supply power to each 6+2-pin header to prevent high power consumption from damaging the GPU. single wire.
There are a few years ahead where enthusiast and workstation PC builders are going to have to deal with graphics cards that require multiple power cables if they need a top-of-the-line graphics card. That is why it never hurts to follow the installation instructions and take into account electrical safety to prevent components from deteriorating.
