You mean for the dual molex to 8pin not to connect ONLY to separately two molex ports but these two molex should be in different ide cable ? Is it okay to power that extra slot with the peripheral connector space? Thank you for helping me! It will draw 75 watts from the pcie slot and 75 watts from the power connection. Am thinking about building a new Desktop. this is my psu- SilverStone Strider Essential 500W ST50F-ES230p i have a 600w PSU, it comes with the case. As contemplated a 5,1 mac pro motherboard offers: I guess you can’t say it is an underpowered one or at least that is what I thought so. 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. I am however custom sleeping and cabling them, and as such are not using the stock cables. It has an 8 pin connector and draws 130w? What graphics card did you buy and PSU (model) do you have? 500w Cooler Master PSU. Hope this helps! I recommend Corsair CX650. Hi Akshat, my rtx2080 needs 8p+6p, for a neat presentation of my build, I don’t feel like using the 6+2p cable plug on that 6p port on graphic card leaving 2p left aside unplugged. I think the issue is because the latch on the card is not in an offset position and is too centered. So my question is: If I want both cards in my system, and both require all power inputs populated, how do I go about it? Which PSU do you currently have? Sorry if this is confusing, hopefully I get clarity with this ! Looking at this PSU, I think 8 pin male to 8 pin male pcie cable should work. https://www.msi.com/Graphics-card/GeForce-GTX-1070-Ti-GAMING-8G/Specification. However, I needed an 8 pin GPU power connector and the spare PSU had only a 6 pin. Well if it has molex 4-pin connectors (which most PSU’s have) then you can use a dual molex to 8-pin PCIe adapter cable to power your RTX 2060. I am so grateful for your help and advice. If you are looking to overclock the card then I think it is better to get the dual 6-pin to 8-pin PCIe adapter cable for stability reasons. The second type converts a single 6-pin plug to a single 8-pin plug. Unfortunately, there are only 2 x 6pin PCIe cables present for powering a gaming GPU, which, I presume, limits the system to a model rated 225W maximum. I have a Zalman ZM-500HP, 80 Plus Bronze. Should I put power connectors on both port? I have a GeForce 2080 overclockable GPU from ASUS. This is common in the power supplies (Y-branch). From CPU we have 2×8 pin socket which is completely required for 1 RTX GPU. I have a GPU that needs an 8pin and 6 pin. Will I need to upgrade my PSU to incorporate this card, or can I use one of the suggested adapters you mentioned in this article to power this card using my current PSU? I have an RTX 3080 and my power supply is a corsair RM750x. The old one has a pair of 6 pin connectors. yap it works fine instaling drivers cant wait play some games on ultra ty . Thanks. Manufacturers do overstate the PSU requirements for their cards because they take into account of overclocking and your overall system specs. For such a power hungry card, I don’t think 6-pin PCIe connector is going to be enough. 6-pin/8-pin. Sorry, i have powercolor red dragon 5700 rx and corsair CV 650w. Well now i just have to buy the Rtx 2060 that is the most difficult part..ahahah. set it to IGPU, or unplug the card. Yes one (6+2) pin will go to the 8-pin and one 6pin from (6+2)pin will go to the 6-pin PCI-E port of the graphics card. Will the new GPU work OK if I use the 6 to 8 pin adapter? Is the same with provided dual molex to 8pin which they give together when you buy gpu or due to low quality can burn my gpu or psu or something like that ? Im looking forward to running Sli. SATA connectors are 3 (they are coming form a 4 pin atx cable attached to a 4 pin ATX port on mobo, this cable has 3 sata connectors, just to avoid confusion, these connectors would provide power to sata hdds or data dvd drive), i have another 4 pin atx connector on mobo as well , currently it doesnt have a cable but i have used it by putting a similar cable which is connected to the other 4 pin atx I just talked about(actually i have 2 different desktops, identical, so I pulled this cable from the other one), your point : 6.25A is the current that a PCIe 6-pin connector can provide at 12V. I got a 450W PSU and it doesn’t have a 8 pin pcie connector ! Because if the 6pin to 8pin can have 150watts, then what about this ? I tried to mount the video card but it doesn’t work and I think the problem is the power supply. What PSU do you have? Thank you so much for all your insight, Akshat, you’re a legend! Sorry, I didnt get where you wanted me to plug the molex cable (not the adaptor). You can go for either SATA to 6-pin / 8-pin or 4-pin molex to 6-pin/8-pin, whichever is available. Well, the PCIe slot can be checked by using another PCIe device on it. Thank You for being awesome! My Dell Precision T5610 has an 850 watt power supply. It is respond to your below reply “Yes and do not overclock it.” but it doesn’t exist the respond choice in this comment & for this reason I post my respond in here. Tom. My previous graphics was a msi geforce gtx 760 2gb so i have to change the pci cable from the psu to my new graphics card. I’ve tried various combinations of the 2 x 8 power leads in the computer (both of the cables have a 6 pin connector with a 2 pin connector that can be used with it. In this case an 8-pin to dual 8-pin (6+2) adapter is a worth a try and may work. before the gpu installation my pc was working fine.. after the installation its gave a lot of issues with blue screen.. since then i have uninstalled the gpu and now the pc is working fine.. Hope this helps. One 8 to 8 and one 8 to 6 to complete each GPU. I read I can use a power cord converter 8 pin to 6 pin and that the other 2 pins are grounds. I’m replying here because there is no reply boton. So you think the 2 molex is safe to pull 150w through? I have an HP Z820 workstation with the 1125 watt power supply. A graphics card with one 6-pin power connector can have maximum power consumption of 150 Watt as it will get 75W from the PCI Express x16 slot and 75W from the 6-pin connector. This card can safely run with 6-pin PCI-e connector too but as it has only an 8-pin PCIe connector, you will have to use an adapter for it. Power supply for only gpu is 330W + 75 from PCI slot would give us 405W so there is some space still. If not second option is 3070 as according to nvidia website it will have 1x 8 pin connector on card and needs only 230W. I am just wondering whether that is fine as there seems to be different versions of the molex to pcie 6 slot connectors?
