Some graphics cards require just a single 8-pin connector. 6+2-pin and 8-pin Power ConnectorsĪ 6+2-pin connector is, for all intents and purposes, an 8-pin one - it’s just divided into two parts, so you could also use it as a 6-pin power cable if need be.Įven though it might look similar to the regular 6-pin, this 8-pin cable are rated for a whopping 150W which, when combined with the 75W from the PCIe slot, amounts to a very respectable 225W. In that case, a singular 6-pin isn’t going to cut it. The higher up the product stack you go, however, the more power-hungry the GPUs become. For most entry- and mid-range graphics cards (especially older ones), this amount will suffice. This cable provides an additional 75W which, when combined with the aforementioned sum, results in a total of 150W. Most graphics cards, however, need a fair bit more than that, which is where the “basic” 6-pin power connector comes into play. In absolutely all scenarios, your motherboard will provide up to 75W of power to your GPU through the PCI Express x16 slot. So, with that little introduction out of the way, let’s dive into the nitty-gritty! 6-Pin Power Connector

The reason why we’re saying this particular part of building a PC is rather simple: you only need to learn the difference between these connectors once and you’ll be set for the years if not even decades to come! The list itself is actually quite short and while it could expand and grow in the future, such changes (or additions, rather) are exceedingly rare and only happen once in a blue moon. The fact that there are multiple different power connectors (all of which happen to look alike) only makes this whole thing that much more complicated.įortunately, there’s a finite number of cables and connectors that can serve as a link between your GPU and PSU. That’s why they’re so alluring, too, but those who’ve never really “dealt” with today’s power-hungry GPUs can (and most often will) feel a bit overwhelmed.Īnd then, to top it all off, there’s at least one cable sticking out - a cable so thin you cannot help but wonder: will it be up to the task of “feeding” your (potentially quite gargantuan) GPU with enough power? Graphics cards, in particular, tend to stand out - they’re often comically large with humongous heatsinks, numerous fans, and shrouds that are either pitch black or laden with RGB.
That, at least in part, is because of the many power cables you’re supposed to connect and all the many components you have to connect them to.
The process of building a PC can, at times, seem exceedingly complicated, what with there being quite some hurdles for one to overcome.
