kenable PCI Express PCIe 6 Pin to 8 Pin Graphics Card Power Adapter Cable 10cm

Product 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. 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..

Now, if your PSU doesn’t have the 8-pin connectors, you can use a Molex to the 8-pin Adapter or SATA to the 8-pin Adapter.

The WORST Trend In Gaming

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. connectors have 2 additional ground wires. The extra ground wires are there only to tell the video card that the connector is different.

I’m guessing its 18amp = 216 watts + 75 watts on the PCix slot = 291 watts max TDP for a graphics card. I think on modern power supplies the 6 pin can do more than 75 watts. The spec was before 2007 for 6 pin = 75 watts as they only had 2 hot wires. Because as your explanation as i can get it, i can use normaly from power supply one 6pin (leaving the 2pin out) and another of 6+2 to the 8pin and it done. So will use 2 cable from power supply per GPU- A you said (Akshat Verma APRIL 12, 2018 in reply to Vinson Mai APRIL 12, 2018 )

A 8 pin connector tells the video card that it may take up to 150 watts through that connector. Power supply manufacturers are supposed to use at least AWG18 rated cables and you'd have 50 watts per pair of wires or around 4A per pair, which is around 40-50% of the maximum recommended current for the wires and connectors. So there's still some room for safety and everything. 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 ? If yes, my psu has two cables which each one of them has 3 sata (6 tottaly) & one cable with 3 molex. This means although I have 3 molex ports, it is NOT recommended to connect the dual molex to 8pin to the two molex of the 3 free molex ports because the three molex are came from ONE cable (and not two) ? If it is correct, then can I go to one cable with 3 sata ports & put one sata to molex so that the one molex of the dual molex to 8pin to connect it here & the other molex to connect to the normal molex cable ? In the link which you gave me it refers that one molex has 1pin 12v., 1pin 5v & 2pins grounds but the 1pin of 12v is 13amps which means 156wattage. Is this true ? Because if this true then we need one molex to 8pin & NOT dual molex to 8pin. Also the article writes about 13 amps in 12v of molex. Is the same for all psu or each psu has its own amps in 12v of molex for example a psu may have 8 amps in the 12v of molex as result this will have 96watts for its molex while other psu will have other wattage for its own molex & for reason to be justificed that general the psu are different total watts because in each port (molex, sata, pci-e pin 6, pci-e pin 8, 24pin mb, 8pin cpu, 4pin cpu) has different amps (in other words difference max wattage) or in all situations of the above ports the amps are SAME & for this reason we say that the 8pin (pci-e) has stable max 150 wattage ? In other words, all the psu has the SAME max wattage for each port ? I read that the 6pin can have more than 75watts but it says if I have understood well, that it has 3 pins of 12v & 3 pins of ground. If the second pin (from the 12v) is NOT connected then the output max wattage is 75 watts while if is connected & then second then is more than 75 watts. Have I understood well ? If yes, how to know if the second pin is connected or not ? Should I see the 6pin of pci-e in each psu to know if this psu has 75 watts or more in its 6pin ? Now about 8pin of pci-e, how is justified the more wattage (if it isn’t exactly the double) from the 6pin of pci-e, while it has two more pins which are grounds (0amps –> 0watt) & NOT 12v so to be logically ? In the end if the 8pin has really max 150 wattage then how the 6pin to 8pin has max 150 wattage or only the dual 6pin to 8pin has really max 150 wattage ? Because if the 6pin to 8pin can have 150watts, then what about this ? https://imgur.com/a/VtW3krX

Answer: 0 molex connectors . 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) Rather than the extra ground pins, both cables have three pins that carry 12V. Most of the time, if you use a 6-pin cable in 8 pin GPU, your GPU will not work. You can read this entire article that I wrote about what you should do if your PSU doesn’t have enough pins for GPU. Can You Use 6+2 Pins For 8 Pins GPU?How would you approach a spare 10 pin connector on an aging server/Workstation Power supply with a proprietary connector – no online documentation of any kind and no one talking about it… But what i would like is to use just one cable, i mean, to get that adaptar and use just one 6+2 from power supply per GPU. 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.

So basically, a 6 pin connector must only be able to do 75 watts, or around 2A per pair of wires, around 1 fourth of the maximum capability of the connector. Suppose you have an RTX 2070 GPU that consumes 175W power and requires one 6-pin & one 8-pin connector. In combination, the RTX 2060 GPU will get (75W + 75W)= a total of 150W power, where the requirement is 175W. Most of the time, the GPU will not work; in some cases, if it works, then your GPU will not perform up to expectations. My issue is that I need to update my GPU from an existing GTX 260 in an old PC. A friend gave me an EVGA GTX 980ti Classified to try before buying and I don’t want to fry it. My CPU is i7-930 2.8GHz. PSU is 700W OCZ Mod XStream Pro. It has 2x 8-pin ports out but the existing 8-pin connectors at the PSU only have 6 wires each, leading to one 6-pin and one 6+2 pin connector on the GTX 260, which has 2 x 6-pin ports. The GTX 980ti Classified has 2 x 8-pin ports and a “TDP” 250W according to this: Your 450 watts has two 6 pin pci-e connectors, probably on a single strand, and probably using AWG18 cables. That means that the whole strand coming from the power supply is physically capable of transferring up to around 250-280 watts of power safely but if that much power can actually be delivered by the power supply is another thing. If it's a single rail design, yes, the power supply could deliver that much. If it's dual rail, the power supply may restrict this to around 200-250 watts - by using two 6 pin connectors, the power supply manufacturer only guarantees it can give at least 2 x 75w =150 watts through those connectors.So basically, with the most common AWG18 wires, a video card can receive through a 6pin or 8pin pci-e connector up to 3 pairs x 8A per pair x 12v = 24 x 12 = ~ 280 watts. Using 6-pin adapters to 8-pin connectors is safe but can’t provide quality service as the 8-pins. These 6-pin adapters can’t be able to run the PC as required, and thus they can cause damage. To avoid risks, consider purchasing an 8-pin connector to be on the safer side.
