  • Advice ?

    So I decided I would buy a second GTX580 for SLI as it was a good deal but now I don't think my AX750 is up to the job of running

    2 SSDS
    2 GTX 580
    2 HDD
    1 Sound card
    1 H100i
    1 2600k 4.4GHz
    So can someone recommend a decent PSU that will easily cope with it all and be some what quite reasonably priced?

    I7 2600K @ 4.4GHz ,R9 280X , Corsair H100i ,Windows 7 Ultimate , 128Gb M4 , 120Gb Vertex 3, 2 x 500Gb WD HDD'S , 16Gb Hyper X Genesis , Cosmos S Black!

    That psu should be fine imo, it's a quality unit.

      Well this review shows a peak of 719 with an i7 965 and 2 580s. http://www.guru3d.com/articles_pages...review,14.html

      As spaceboy says, its a high quality unit and the seasonic ones are always underrated in terms of actual output they can do.

        Thanks just spent the last hour or so looking around the net and everyone I came across seems to recommend a 1000w+ PSU as they said SLI 580's peaked at 719w alone.

          It's almost impossible to measure just what GPUs produce, any power readings are usually for the full PC (as per Chaz's link above). I've previously run 2x 570s on my Seasonic X-650 and it was perfect. As the AX is basically the same as the X-series, and you have 100W more, I am positive you'll be fine.

            Just make sure the PSU can breath properly if its mounted normally, or you have good airflow if its fan up and it should be fine.

              i would've thought it would be ok, maybe try to knock a little bit of volts off your cpu to help out?

                Thank's for the reply's guys I am glad I don't have to spend even more on another PSU as I only got this in November as it works a treat already. The PSU is mounted at the bottom of the case with fans up My vcore at 4.4 is at about 1.30

                  If its close to peak performance, they can get a little warm. With that in mind, you should be more than fine as long as the PSU has adequate ventilation for the fan.

                    A pair of GTX580's running at full load with your system spec is going to pull around 700w total system power draw. You have a excellent psu but that's still cutting it a little close for my liking. While your AX750 will probably manage it, it will be running at not much off full load so the fan will probably ramp up as well. To be safe i would be looking at something 850w+. Have a look at the XFX Pro Black Edition 850w. It's 80+ gold rated, fully modular and is built by Seasonic. If you want to play it really safe take a look at the XFX Pro Black Edition 1000w. Also a Seasonic build and fully modular but 80+ Platinum rated.

                        You will be fine with what you got mate

                        Here is what Kitguru had to say

                        In the real world we tested this PSU with an Intel Core i7 970 at 4.5ghz with two 5870s in Crossfire X and experienced a fully stable system, even when running Furmark under dual GPU mode with Prime 95 in the background.

                          So I added 3 fans at the front of my case to pull in some nice chilled air and it seems that the AX750 has no problems running both cards when playing BF3 maxed out.
