6 pin to 8 pin connectors

I’m looking at getting a 1070 card to replace my slightly out of date 570. Only problem is the 1070 needs 2 8 pin lines. Where as the 570 needed 2 6 pin lines. I have seen a 6 to 8 pin adapter cable. Just wondering if this would work? Or do I need a new power supply.

Basically over the next 6-7 months ill be building a new computer. But I figured if I buy the graphics card now I can limp my current pc along until the new one is up.

You may need a new power supply … not for the connectors but for the extra load.

The molex 6 to 8 will be ok, but use a power draw PSU calculator to check if you need to buy more oomph.



The 570 requires 550w minimum ps. And the 1070 requires a 500w minimum ps. So would I be safe in assuming I would be ok? Ill run the calculator when I get home.

I think so, in that the Pascal chipsets do draw less power than previous generations, but worth the calc for sure.

My new GTX 1070 needs a lot less power than my old 680, actually my new PC as whole draws less power than my old one.

ASUS Maximus VIII Ranger, i7 6700K (still at stock 4.2GHz), Gainward GTX 1070 8GB Phoenix, 32GB DDR4 RAM G.Skill Ripjaws, 2xSSD, 1xHDD, Corsair RM650X
Gigabyte GA-EX58-UD4P, i7 920 @4GHz, Gainward GTX 680 2GB, 12GB DDR3 Kingston HyperX, 3xSSD, 2xHDD, Enermax Pro 82+ 525W.

What I found to be the nicest feature of the 1070 aside from its amazing performance is that it doesn’t even turn on its fan until it hits 51°C and even under load it barely goes beyond ~400RPM
