So the fundamental question is, can I run a 2080 Super with my current PSU, or is it safer to buy a new one?

I don’t know exactly how much it delivers on PBC 8 pin header. the 12V says 18amp about 8 places. So its either 18 amp or 18 x 2. I’m guessing its 18amp = 216 watts + 75 watts on the PCix slot = 291 watts max TDP for a graphics card. Incredible Blog; impressive amount of knowledge you’re sharing with others. Here is one to challenge you. My answer would be easy if any documentation existed.. The 8-pin has an equal number of power pins but two more ground pins than a 6-pin PCIe power connector. An adapter works as the extra two pins can be grounded, but the current carrying capacity reduces. This change of mind return policy is in addition to, and does not affect your rights under the Australian Consumer Law including any rights you may have in respect of faulty items. If true i’m strugling with the 6pin, because if 8pin cable can get “just” 150W and i get the adaptarer, the cable from power supply will be recieving more Watts than it can.??This smooth running may be absent; instead, an explosion may occur. The critical problem is that you’ll be maxing out a cheap PSU that may cause dire consequences for upgrading. The 8-pin power connector can deliver a maximum of 150W to your graphics card. So if your graphics card power consumption is more than 150W then it will definitely come with an 8-pin connector or two 6-pin connectors. A graphics card with one 8-pin power connector can get a maximum of 225W of power, 75W from the PCI Express x16 slot, and 150W from the 8-pin connector from the power supply. The latest High-end graphics cards come with the 8-pin power connector and some of the power-hungry top-end graphics cards can have both 6-pin and 8-pin connectors or two 8-pin connectors. A graphics card with both 6-pin and 8-pin connectors can have a maximum power consumption of 300 Watt (75W + 75W + 150W). well if the card is under powered(card wont get any harm), the card will get harm only if its overpowered. This is my understanding

The card I’m looking at requires 2 x 8-PIN connectors. I guess I could get a 2 x 6-Pin to 8-Pin Y cable, and also a 2 x Molex to 8-PIN Y cable, this should according to my calcs give me 282W of power which exceeds the 250W requirement of the card, however I don’t fully understand how the dual rail thing works and the fact that each rail is limited to 18A. A PCIe power spec maxes at 150W per 8-pin connector. A daisy chain is suitable if your high-end GPU uses 150W or less. A 6-pin power connector can supply 75 Watt to the graphics card. So if your graphics card power consumption is more than 75W then it will have one 6-pin PCI-E power connector for its working. A graphics card with one 6-pin power connector can have a maximum power consumption of 150 Watt as it will get 75W from the PCI Express x16 slot and 75W from the 6-pin connector. Most of the mid-range graphics cards from both Nvidia and AMD come with the 6-pin power connector.Looking closely at a 6-pin and an 8-pin connector, you notice that the 8-pin has two extra ground pins. Both of them have three pins supplying +12V. Taking into account the above mentioned stuff do you still confirm it is proper to use 2x6pin to 8pin adapter? Are you concerned about whether using a 6-pin to 8-pin adapter is safe? This article seeks to answer the question and reduce your worry. A GTX 1080 may have 2 x 8 pin connectors, but that doesn't mean the video card will use up to 2 x 150 watts or 300 watts. In reality, the video card will use up to around 160 watts, maybe a bit more... let's say 180 watts. Furthermore, around 20-40 watts of those 180 watts are taken from the pci-e slot and not from the pci-e 8 pin connectors, so in real world, the video card will only take around 150 watts through those 2 x 8 pin connectors

When choosing an 8-pin connector, consider your computer’s workload and select an adapter of good quality. FAQs Can you use a 4-pin on an 8-pin motherboard?The GPU has 1 x 8 pin and the other is a 1 x 6 pin. I have completed the 8 pin, but i’m confused about how to connect the 6 pin So recently I bought a RTX 2060 (THIS ONE: https://m.kabum.com.br/produto/100371/placa-de-v-deo-gigabyte-nvidia-geforce-rtx-2060-gaming-oc-pro-6g-gddr6-gv-n2060gamingoc-pro-6gd?gclid=EAIaIQobChMIxLbI1bmH6QIVyAaRCh2WUwH_EAQYAiABEgJJtvD_BwE ), that needs a 8 pin cable. I have a 6-pin cable coming from the PSU, a 8-pin to dual 6-pin adapter (THIS ONE: https://encrypted-tbn0.gstatic.com/images? ) and a 4-molex to 8-pin adaptar (THIS ONE: https://encrypted-tbn0.gstatic.com/images?q=tbn%3AANd9GcRL11QvJQUjC1N-ybq8VmPvHdKd2B-OCS2TqAhp6HeS2hA-A8LL&usqp=CAU) I am trying to understand how a 2x SATA (108w combined) can work with an 8-pin PCI (150w) connection without overloading the SATA connections, and perhaps damaging the motherboard or other components ?

Below you can see Nvidia’s top-end graphics card GeForce GTX 1080 Ti with both 8-pin and 6-pin connectors. This card has a maximum power consumption of 250 Watt. The Final question would be: Can the Single Pcie 6 Pin to 8 Pin Adapter power a 160-190 Watts RTX 2060? If you use these adapters, then RTX 2070 will take 75W power from the motherboard’s PCIe slot, 75W power from one 6-pin cable, and 54W via adapters. I know one guy that got twin 1080s working but it was not stable running both off the 8 pin PS pcb header. That would be 180 + 180 = 360 watt. He got it stable by running the other off a header meant for hard drives and accessories. First, let me say that you are amazing. You’re very kind to help so may people for so long. Your article here is very informative and has excellent information.The only reason I care is I have a few Dell graphic workstations that came with dual 6 pin that powered graphics cards a bit beyond office specs. I ran a 1080 in one (no issues) had to to a 8 pint (of the PS pcb board (they are modular and have no wires, more like a server PS that you just slide in and it connects for a PCB edge connector. Two of those would be a lot more costly than the other options. I don’t have any spare molex or sata connections left to use. If your PSU has a 6-pin cable and if your GPU needs an 8-pin connector, then in a situation like this, you can use a different type of Adapter available in the market. Also, I cannot find any information on how the S12 is wired in terms of which cables come off which rail (or maybe I’m completely misunderstanding how a dual rail PSU works?) I have been running a GTX 560 since 2011, and have just bought a RTX 2060 as an upgrade. The old one has a pair of 6 pin connectors. The new one 8 pin.
