Question on wattage of power supply & graphics card

Ok, so I currently have 1 AMD HD Radeon 7770, and was looking to upgrade to a HD Radeon 7950, so when i thought of getting that I noticed i needed a new power supply so im going to get the CORSAIR AX860i, then today i wanted to upgrade and get 2 HD Radeon 7950's. The 7950 have a minimum of 500w. I want to know if i can run 2 7950 on the AX860i or if i would need more wattage.

    1. This is a bit easier with nVidia as they still list system requirements on their web site for all their boards. AMD is little shy now about doing this since the R7 / R9 series came out.

    2. Guru3D does an excellent power consumption section in each of their card reviews....if ya ever wanna know what PSU ya need, just google "Guru3D [your card]". For example:

    Here is Guru3D's power supply recommendation:

    Radeon HD 7950 - On your average system the card requires you to have a 500 Watt power supply unit.
    Radeon HD 7950 Crossfire - On your average system the cards require you to have a 700 Watt power supply unit as minimum.

    If you are going to overclock the GPU or processor, then we do recommend you purchase something with some more stamina.


    I would use at least a 750 watter.....and 850 if you real aggressive in the OCing or water cooling everything.

    The $220 AX860i is a very good PSU.....but so expensive....the older HX850 is much cheaper and actually has lower ripple and better voltage stability.....

    Great PSUs - In order of preference.... I'd put the EVGA abd Corsair HX on equal fotting but gotta like the price on the SuperNova

    Thank you for the wide selection of PSU's I think i'm gonna go with the HX850 i don't mind spending a bit more over the SuperNova 850. Thank you again!
  3. The Seasonic X series is #1 .... it usually gets 10.0 performance and 10.0 Build Quality ratings.... the other two usually get 10.0 / 9.5 and the Seasonic is cheaper right now.
