DO NOT use any kind of adapters. If your PSU does not have the proper cables, it's for a reason. Buy a proper quality PSU instead. Your system will be safer and you as well, since using questionable adapters with questionable PSUs, may become a fire hazard.

you will need a molex adapter.

Or better yet, just get a better power supply. If it doesn't have an 8-Pin, it means that it wasn't meant to support 8-Pin graphics cards.

Each 6-pin connector is rated to carry up to 75 watts.

An 8-pin connector is rated to carry up to 150 watts.

A 2x6-pin to 1x8-pin adapter is safe to use in this situation.

That is the ONLY kind of adapter I would say is safe. In ANY situation with video cards, ONLY the following are safe:
  • 1x8-pin to 2x6-pin
  • 2x6-pin to 1x8-pin
Anything else is a fire hazard.


This is all assuming that your PSU provides enough power AND is of high quality. To know for sure, I will repeat @hang-the-9 's question - we need to know the brand and model of your power supply.
