People use 6->8 pin adapters all the time and as you already said, the 6+2 pin connectors only add 2 more ground wires. SATA includes both a data cable and a power cable. Advertised sites are not endorsed by the Bitcoin Forum. And if you plug in the wrong kind of cable then expect fireworks. have a peek here
There's a reason the card needs 2 connectors. Some of them are missing the 3.3 volt wire.

That is, it only fits into one end of the motherboard connector unless you force it. But you should avoid using that kind of adapter if you can because the extra wire and connector are just more things which can go wrong.

They may be unsafe, untrustworthy, or illegal in your jurisdiction. The other main rail is 12 volts. These are pretty common on the 3.3 volt line in pin 13 but are sometimes used for other voltages too. How To Connect Graphics Card To Power Supply If you have one of these connectors on a motherboard then you must plug a power cable into it or your CPU won't get any power.
Normally this kind of peripheral connector has "fan" printed on it to warn you. Pci-e Cables But the losses get worse as the current rises. If you draw a little more wattage then the maximum, the hardware doesn't immediately burst into flames. People with older power supplies often use adapters which convert from 4 pin peripheral cables to SATA power cables.
But since 4 pin peripheral connectors only supply 5 and 12 volts, the SATA connector is missing 3.3 volts (there's no orange wire). Graphics Card Cable Monitor Overclock memory. VGA video card outputs Useful technical information How to install your motherboard chipset drivers Test your motherboard memory with Memtest86 Torture test your CPU with Prime95 How to find specifications for If you look carefully at the picture above you can see that four of the pins are square and the other four have rounded corners.
The 6+2 PCI Express power cable is made up of two pieces: a 6 pin piece, and a 2 pin piece. The motherboard connectors also have the same square and rounded arrangement so the power cable only fits in one way. Graphics Card Has 2 6 Pin Connectors That's the same as it is with the 6 Pin PCI Express power cable. Graphics Card Power Cable 6 Pin Even if the motherboard works with a 4 pin 12 volt cable, you are still only providing half of the current carrying capacity which would be provided by an 8 pin
If you plug them both into the same power supply cable then you are drawing all the power of the 8 pin 12 volt connector through a single 18 gauge wire. http://internetpasswordpro.com/graphics-card/what-graphics-card-should-i-get-for-gaming.html The Dell PCs which were carrying this ticking time-bomb were made between 1996 and 2000. Sadly, some large computer vendors like to lock customers into buying upgrades from them rather from a third party. one cable transfers all of the power from the psu to the video card... Graphics Card Power Cable 8 Pin
keybaud Full Member Offline Activity: 121 Re: Why do they even require two pcie power slots in a video card??? The -5 volt line on pin 20 was made optional in ATX12V 1.3 (introduced in 2003) because -5 had been rarely used for years. If there are no labels then you can usually use wire colors to tell the two kinds of cables apart. http://internetpasswordpro.com/graphics-card/ddr-graphics-card.html Even if they're keyed you can insert them the wrong way if you put a little effort into it.
In all likelihood, however, real implementations of this power cable can provide far more than 75 watts. 8 pin PCI Express power cable The PCI Express 2.0 specification released in January Graphics Card Cable To Motherboard You don't have to worry about inserting it the wrong way. If you use an adapter then be sure to plug the 4 pin peripheral connectors into separate cables coming from the power supply.
The 8 pin cable has enough pins that it's pretty hard to insert it in the wrong direction but determined people might be able to do it. The wires will simply overheat. But both halves of this 4+4 will fit into a 4 pin 12 volt motherboard connector. Graphics Card Cable Types Nonetheless, information leaks out from the specification and the 6 pin PCI Express power cable is actually rated at an extremely conservative 75 watts.

Some of the two-wire peripheral connectors are for speed-controlled fans. An error (403 Forbidden) has occurred in response to this request. If you plug the two pieces of a 20+4 power cable together then you have a 24 pin power cable which can be plugged into a 24 pin motherboard. 4 pin Many PCI Express video cards which have the 6 pin or 8 pin PCI Express power cable still draw a substantial portion of their 12 volt load through the PCI Express
