Lane 0 and 1 may swap in the IC of the device connector. (No swapping occurs if the accessory identification chip is connected to the ID0 pin.) As a solution to this problem, you can use a combination of connector and cable types. The 6+2 connector type is the most common connector that you can use. You can connect your 6-pin cable to a 6-pin connector and draw 150 watts instead of just 75 watts. Apart from that, the cables in 6+2 connector’s type also come rated to offer 150 watts with six-pin cables without catching fire. Any Standard motherboard of a CPU nowadays comes with a PCIe x16 connector. This connector mentioned above has 16 slots to offer power to GPUs. In the PCIe x16 connector, the maximum power supply you can expect is 75 watts. Using high-profile graphics cards like RTX 3080 can load the motherboard and consume more power.

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.

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. SATA to 6-Pin PCI-E Adapter Cable – This adapter converts the SATA connector to a 6-pin power connector for your graphics card. If you are short on Molex connectors then you can use this converter cable or adapter. IF your power supply has only one 8 pin connector, the first thing you should do is to look at the label of the power supply and see how much current the psu can actually supply on 12v (doesn't matter how many adapters you have, if the power supply can only produce 250-300w on 12v) and second ask yourself if you trust the power supply to not lie about its capabilities on the label. If it's from a brand with decent reputation, chances are it's not lying. If it's some cheap model or some chinese psu that came with the case, most likely the psu is inflating the numbers. The 6-pin graphics connector is usually common in lower and mid-range graphics units. As the name says, the connectors have six-pin connecting slots with a 4.2 mm pitch. These GPU connectors can directly draw up to 75 watts from an external power source. The power even comes bypassing the motherboard. Six-pin GPU connectors are suitable when a graphics card demands a minimum of 150 watts of power. 6-Pin GPU Cable but on the other hand here (also nvidia forum) we can read that 2xpin to 8pin adapter isn’t safe at all:video cards don't take all power from the 8 pin connector. They can also take up to around 65w from the SLOT. (officially it's 10w on 3.3v and 65w on 12v but recently I think they loosened the standards to allow up to 75w on 12v) This cable uses a double 4-pin connections and adjusts them to an 8-pin connection. 4-pin to 8-pin is something that will probably be handy with advanced graphics cards. 6-Pin to 8-Pin PCI-E Adapter Cable Thank you for the info and rapid response, Ashtak – it’s much appreciated. Despite enquiring about Radeon cards, I had considered the various GTX 1660 models as I was aware of Nvidia’s sudden and unexpected ‘compliance’ with Freesynch. I simply wondered if there was anything to be gained in monitor performance when using Radeon cards as the technology was created by AMD for their own products. 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.

If a 12.5A 6-pin connector on an older power supply is connected to a newer 8-pin PCIe device, the PCIe device should not turn on because it doesn't know if a 12.5A compliant connection has been used. If all 6 wires are present on the 6 pin connector and the power supply can handle the current, then it is safe to get an adapter that will convert the 6 pin connector in to an 8 pin connector simply by grounding the two additional connections on the 8 pin connector. The SATA came as a replacement for the PATA connectors. Earlier, the PATA connectors had 34- 40 pins, so to save space, the SATA connectors replaced them. These connection types were designed to offer high-speed data transmission to storage devices, optical drives, and graphical units. However, SATA has become older now.

You can have pci-e 8 pin to 2 x pci-e 8 pin adapters - these would be your best bet. You know the input can take nearly 300w and then you have 2 8 pin connectors, so lots of wires between the input and output. If your power supply does not have 6-pin or 8-pin connectors then you may try these 6-pin and 8-pin converters or power adapter cables to power your graphics card.

I Swapped the CEO's Assistant For a Day!

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

An 8-pin GPU cable is a power connector common in most high-end graphics. These connectors usually have a 4.2 mm pitch that can seamlessly offer a power supply of 150 watts. If you connect a graphics card with an 8-pin connector, the maximum power supply you can draw is 225 watts. You will get 75 watts from the PCIe x16 slot and 150 watts from the eight-pin connectors. An 8-pin GPU Cable SATA connectors to 8-Pin PCIe adapter cable offer you compatibility with your 8-Pin GPU power cable. Most of the older PSUs have 4-pin SATA connectors, and thus, for one 8-pin PCIe, you would require 2- Pin SATA connectors. This adapter will help you achieve connectivity and draw 225 watts of power supply for your GPU. 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 most recent example would be NVIDIA 3000 series development by NVIDIA, and it came along with 12-pin connectors to draw the power supply needed by the GPU. 5. Can A 6-Pin PSU Connect To An 8-Pin GPU Connector?This cable converts your SATA connectors to a 6-pin connector, but this is generally advised against. There is a chance that SATA won’t be able to handle the power that your graphics card requires, and this is not something that you want to encounter, especially if the cable is labeled as “ SATA only“. SATA to 8-Pin PCI-E Adapter Cable Despite 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. As 150 watts will be enough for most mid-range cards, these usually feature the 6-pin power connector. a b "Lightning to USB 3 Camera Adapter". Apple Inc.
