Molex to 6 pin adapter question

[daBizMan]

Hello,

I'm buying a R7 265 which needs a 6 pin connector. My PSU only has a 4pin and 2 molexes, so that means I need to get a molex to 6pin adapter. Some adapters come with 2 molex plugs and some with only 1. Is there a difference between them? Can I just plug in 1 molex instead of 2? Because the 2nd molex is powering up my fans and I don't want to get another adapter.

P.S: I have a 300W PSU and theoretically I will have about 30 extra watts. The card takes 140 and CPU takes 130. Not sure if this is safe.

No, that is NOT safe. You are dangerously close to the limits of your PSU. Please post the make and model of your PSU, since some PSUs cannot even deliver the rated power.

The motherboard, fans, and hard drives all also has a demand on the PSU wattage, so your calculation is way off.

I have some coolmax PSU. But what about the connector question?

Coolmax is absolute rubbish and terrible. It's at tier 5 - the lowest tier n this list

Your molex question should never be answered, since it will simply be dangerous to even attempt to power an additional GPU with that PSU.
