Be careful because with great power comes a greater risk of overheating. However, if you’re building a gaming rig with an RTX 3080/3090 or if you want to future-proof it (which is almost impossible), you should choose a more powerful PSU. In any case, it’s safe to say that your machine will be properly powered with a good 650 watts PSU. An example of such a GPU is the GeForce RTX 2080 Ti LIGHTNING Z. These are usually the manufacturers’ highest-end models made to provide the best possible cooling and overclocking. In even rarer cases, there are enthusiast GPUs that require three 8-pin connectors. In addition, you still need to power the CPU (which is another big energy consumer) and the rest of your PC’s components. By simply adding the numbers together, we get a total of 375 watts, but that is an extreme amount.

There are even some exceptional cases where the GPU will have two 8-pin connectors. As a result, it has a maximum power consumption of 170 watts. For example, NVIDIA’s GeForce RTX 3060 has both types of connectors. The most power-hungry graphics cards will come with a 6-pin and an 8-pin connector. If the GPU requires more than 150 watts, it will come with an 8-pin connector or two 6-pin connectors.Īs always, there are exceptions. 8-Pin Connector An 8-pin connectorĪlthough the math might not seem right when compared to the 6-pin connector, the 8-pin connector can deliver 150 watts to a graphics card. The terms “PCI Express cables” or “PEG cables” (for PCI Express Graphics) can also be used to describe 6-pin connectors. As 150 watts will be enough for most mid-range cards, these usually feature the 6-pin power connector. This means the graphics card will use the PCI Express x16 slot and also draw power directly from the PSU (Power Supply Unit).ĭespite the fact that 150 watts are enough for most graphics cards, high-end cards such as NVIDIA’s RTX 3080 require more than 320 watts and system power of 750 watts.

This connector can supply the GPU with an additional 75 watts of energy. As none of these GPUs have a lot of processing power, they don’t need more than 75 watts of power. Here are a few examples of GPUs that don’t require any external power: GT 1030, GTX 1050 2GB variant, RX 550, RX 460, and many others. Some feature multiple PCI Express x16 slots in order to connect more GPUs but, as previously mentioned, this increases the power requirement. This guy was trying to do it all over one wire, if you look they all hook together and the fire started right where it all pinched down to the one wire back to the PSU.Motherboards come with the aforementioned PCI Express x16 slot that can provide a maximum of 75 watts of power. People do get away with it, so its your call.

While the wire may in fact take full load the molex pins are sort of notorious for having dodgy contact and melting. I have done it.Īs was stated by the other poster, it seems like people are in fact getting away with feeding those six pins split down to 2 wires from the PSU, but I can't really recommend it.

Too much current across too small of wires and they get hot, possibly until the plastic insulation drips off and combusts. When you load up your GPU it will use more power, that is to say its impedance will drop, and more current WILL flow across those yellow wires to feed it. Think of it like this, if you hook a long ass string of christmas lights to a car battery, that is a lot of resistance/impedance, so not too much current will flow, now drop a 1' copper bar across that same car battery and you are going to have some fireworks.low impedance=high current. For a lower impedance more current will flow at a given voltage. The impedance of a circuit sets the ratio of potential to kinetic energy in a system. Now, there is one remaining electrical property we call impedance, measured in Ohms. Amps we don't really know because the GPU will get some of its current off the PCIe buss but we do know that nVidia saw fit to put connectors on there. The yellow wires that need to go to the GPU are connected to the PSUs 12 V rail, so Volts we know. You need both of them to get any work done, in fact Watts is defined as Amps x Volts. It is the actual number of electrons flowing in the wire. There is an electrical property known as current, measured in Amps (or Amperes in the UK).
