GTX 1070 pins?

[RealListless]

Hi all. Currently upgrading from a (I suspect to be broken) GTX 980 with 6+8 pins (using 6 and 6+2 cables) to a GTX 1070 with 8+8 pins. I realised this too late (I know, I know) as the card just arrived and I was wondering about power usage. I saw another thread claim filling one 8 pin is enough for the 1070. Is this true? Can I use a 6+2 cable to supply enough power for the 1070? Or should I go get a 8 pin cable? The card also came with two adapters (two six pins into one eight pin for each), should I plug two 6 cables into one of these instead and would using one adapter only be enough?

Thanks

Worth trying - the slot provides about 75 watts of power. The slot power plus the power of one connector might be enough for most cases.

Worth trying the adapter and plugging a 6 and 6+2 (leaving the 2 dangling) into one 8, or just plugging a 6+2 directly into an 8?

Hello... Typically you need to fill every pin slot, because the card will have Voltage detection logic employed (safety/mis-use) ... Use a 6-pin to 8-pin adaptor to satisfy the logic and for your further tests on the card.

Extra power phase is more so for over clocking i believe. two 6 into 8 should work i wouldn't see why it wont

Hello... a GPU is a LOW voltage HIGH current device... Multi Traces and Pins will be used to safely distribute this high current. Due to Product and Consumer safety and possible mis-use, Anti-measures had to be employed.

Companies and Engineers spend their time and $$$$ to design counter measures into their designs and products. They sure wish they didn't... it's easy to make/design something that works, But you spend a lot more time dealing with ways/ideas in which to Prevent the MIS-Use and law suits. ( after a while you don't any more surface area on the product too put any more warning stickers on it... B D )

Putting a 8 pin connectors on the Video card would seem logical enough to tell the consumer to connect a 8-pin into the connector for power requirements... but that didn't seem to work for you B ) So the company had to employ more logic, time and $$$$ into preventing the Consumer (you?) from using (mis-using?) the product in this way B /

The Video card company wishes it didn't have to include the FREE 6 pin to 8 pin adaptors in their product Box... but there again they are aware of what the Video card needs at the power inputs, and wants the Consumer a means to get it up and running fast, and of course, with a happy safe consumer too.

Try one 8-pins cable from the graphics card manufacturer so that the pins configuration integrity is maintained. This is true for PSU cables and the cables are not inter-changeable within the same manufacturer. (Corsair HX850 cables are not inter-changeable with Corsair AX850 cables even though they look similar; the pin-outs are different and maybe the OEMs are different).
