PSU with 6pin connector, R9 380 requires 8pin, can an adapter work?

I'm upgrading my graphics card to a R9 380. My only problem is that my PSU only has a 6pin connector. I was wondering if I could use one of these:



It's an older 500W PSU which has served me very well since I've had it.

  1. Depends if its a decent quality unit & what CPU you're running.

    The 380 is a 180w GPU , you really want a 12v rail with s minimum ampage of 32a even if you're running a sub 90w i3 or i5.

    Without actual PSU specs its impossible to say - I would hazard a guess that its not great idea though , any 500w should come with a minimum of 2x6 pin connectors , if it doesn't it normally means they're not up to the job.

    Thanks for the reply, i should have mentioned my specs

    I'm running an i5-6402P CPU, an Asus B-150Pro Gaming mobo
    and my psu is a Chieftech A80 and it has 2 6pin connectors.
  3. This model?

    Shows 2x6+2 pin & 40a 12v so while sketchy quality wise it is enough on paper.

    Seeing as youre saying you only gave 6 pins though yours must be an older model.

    It's a close match, here's pic of my PSU http://. The model number is almost the same, except that the one you linked starts with an A.

    And yes it's an older model
  5. Hi
    according to this ; http://
    Max current that can be carried by Molex pins is 8.5A so using two would be 17A .
    If that is a 180W GPU this would draw 15A so in theory would be ok.
  6. Radeon R9-380 - 28A and a 500W psu minimum, If its only rocking 1 6pin plug i would really look at getting a new PSU. I also go buy the rule if said PSU does not have the right Pci-e plugs needed for said GPU its time for a new PSU.

    Makkem - theoretically correct in everything you've said HOWEVER I have to agree with faalin .
    Chieftec were never a good brand & while it may have served you well its very likely never seen the kind of loading it will do with the 380 .

    Even a $30-$40 budget unit like the evga 500 would be a vastly better choice for your spangly new $200+ GPU.

    Up to you though mate at the end of the day.
  8. You're all right, I've decided on a new PSU, a COOLER MASTER B2 RS-500-ACABB1-EU, which is affordable and is better.
    Sadly in my region we don't have many options when it comes to brands so CM is the best I can go with.

    Thanks again for the insight.
