    DX79SR and PowerSupply Question

    miker

      I'm building a new PC using the Intel DX79SR (maybe the ASUS Sabertooth X79) with an i7-3970X.

       

      Components:

        • PNY NVIDIA NVS 510 2GB GDDR3 4-Mini DisplayPort (There will be no high-end graphics cards.)
        • OCZ Technology 512GB Vector Series SSD
        • Seagate Desktop HDD 4TB SATA drive
        • 32GB memory

      Will be liquid-cooled but likely will not attempt to over-clock it.

       

      I have a Zalman heatpipe cooled 600W ZM600-HP power supply and would like to know if you think it will be sufficient.

          Your CPU alone will need about 200W on full load. Since you are using a very low power GFX card "the card you mentioned only draws 35W", then the Zalman PSU will be enough.

          HDDs, SSDs & RAMs draw very little power.

          My guess you've owned that PSU for some time now; with time & heat all PSU degrade their performance. Still it's enough for the rig you mentioned.

           

          With all do respect to Intel,

          I won't go for an Intel MB, they are so entry level, even for their extreme line "e.g. x79". Personally I'm a Gigabyte fanboy but if you like Asus go for it. There are plenty of boards out their that will crush the Intel's DX79xx

            I appreciate your reply.  I'm relatively new to building my own PCs, so have limited experience; it's always confused me on how to compare various manufacturers.  I've read positive and negative reviews about every one.  If they all basically use the same components and have the features one wants, what is it about an Intel board that makes it "entry level" ?   What is it about Gigabyte boards that make them a better choice?  Is there one for the x79 you'd recommend?  What features should I look for when comparing?

              I'll try to be as brief as possible cause the list is practically endless & won't go a lot into technical details

              Features missing on Intel boards that EVERY other major company has made available on their boards:

               

              "specific to the x79"

              • Native PCIE 3.0 support:

              While every board on the market supports PCIE Gen. 3, Intel's DX79xx doesn't support it. Which means if you have a high end graphic card like the GTX 690 or the soon coming GTX 790 it will bottleneck on the PCIE 2.0

              • GUI BIOS:

              Graphical User Interface BIOS has been implemented on the all x79 boards except the ones from Intel. Generally speaking professional over clockers prefer the conventional BIOS, that's why you can switch from conventional BIOS to GUI in all motherboards except the ones from Intel "only old BIOS". Hence, that's one step towards being basic. Some non Intel boards offer two BIOS one for OCing  and one for regular use.

              • Better Over Clocking:

              While the DX79SR or DX79SI offer 8 phase PWM other boards have up to 12 phase PWM  "note that 8 is not bad but, 12 is much better"

              • Aesthetics, Finishing, & components:

              Right now I have the DX79SR & the Asrock  x79 extreme 11. Take a look at both & you will visually realize the better layout design, better gold plated components etc...

               

              Maybe, you will think that these non Intel boards are loaded with features that you won't use. However, the price doesn't differ that much. In some cases, the are cheaper X79 boards then the one you want to buy "DX79SR". The Asrock is a 600USD board but, there are plenty of others out there that are cheaper. It all depends on your budget.

              Intel doesn't really care for the enthusiast segment. However, the x79 chipset is specifically designed for the enthusiast segment & the CPU you are buying is the most powerful CPU up to date.

               

              Bottom line, don't get that confused with the negative reviews & positive ones "every product has both". I'm not saying that the DX79SR is a bad board but, for that price you can get a much better board. Maybe, if I know what your budget is, I will be able to help you much better with the hardware starting from A to Z. Surely, if I knew what it would be primarily used for I would be able to recommend one.

               

              If I had to recommend an x79 board it will be the  MSI Big Bang-XPower II "you can't go wrong with that board".
