Hello everyone,
 
 This is my first post here, as I just bought a new graphics card - GTX 1060 SSC.
 
So my case is this (I know almost nothing about graphics cards etc., so don't laugh):
My old GTX 650 was using a 6pin connector and obviously my PC has it. Now, the new one requires a 8pin connector which came in the box. So on one end of the cable there is the male 8pin connector and the other end a dual female 6pin connector. I have a Cooler Master k280 case with 500W PSU. The only cable that goes out of it (which I can use for the card) is the old 6pin connector which of course I could connect to the dual 6pin, but I don't think that this will work properly, since the other female 6pin won't be used.
 
So can I find an adapter for this and will it be able to run with my new GPU without causing issues?
Do I need to buy a new PSU?
 
Thanks,

Looks like that unit only has the single six pin.
Your options are as follows, connect the second 6 pin with a dual molex adapter, shown HERE, not recommended as the two adapter solution may not work long term.
Replace the PSU with a unit that has a single 6+2 PCIe power connector so that no adapters are needed. All the EVGA units would work, our two 500w models are linked HERE.
Or to return the card and get a GTX 1060 that only requires a single 6 pin PCIe power plug, the single fan models have only a single six pin and the SC model is linked HERE.
