    EVGA is one of the elite NVIDIA partners that sells NVIDIA-designed motherboards based on the nForce chipsets, apart from being a leading graphics card vendor. EVGA for one, added innovation to the NVIDIA designs with its own level of enhancements, such as improved capacitors, more number of CPU power phases than NVIDIA's own designs, among others. EVGA brands these higher-grade motherboards under the "FTW" series. If you've spent long enough time on an internet bulletin board, you would know that FTW means "for teh win".

    EVGA decided to give its flagship motherboard, the nForce 790i SLI FTW an improvement with its power circuits. The new board, 790i SLI FTW PWM circuitry a digital upgrade. The board features an 8-phase circuit for the CPU. It also provides digital power management. This is said to push up its overclocking capabilities. The board provides vDroop control and onboard power, reset and clear CMOS buttons. The motherboard supports all LGA-775 socket processors including the ones with 1600 MHz FSB. It supports memory with speeds of up to DDR3 2000 MHz. The nForce 790i SLI FTW DIGITAL PWM is now on sale at $339.99, $40 higher than the older nForce 790i SLI FTW.

    I see two 4 Phase SMD Coupled Inductors and maybe 8 Multi-Phase Switching regulators. This way you will have rock stable 250 Watt CPU power circuit and no limitations for overclocking. Still there is weak a cooling for Switching regulators. These chips will get pretty hot, I think. Last time I checked Voltera specifications there was a 150 degree Celsius max temperature, so it is OK.

    Great to hear. Go eVGA. If only you branched into ATi with your quality. Sad though, I can't find my 680i A1 on the Egg anymore.

    I have the 790i FTW and it says it has 8 phase pwr management so i am not sure what the new one has to offer.

    So the difference is ....

    It's interesting , yo do'nt see the mosfets and there is only the heat pipe by the output stuff, none on the side of the cpu. I would be interested in how well this digital PWM works and what effect you really see, will i get better overclock, or just less ripple voltage and less vdroop or what....
    Seems i need a EE to give me a better answer.

    I wonder what that really means for the board? DPM hmmmm, need to do some reading.


    thanks for pointing out the new Evga addition!

    It is something called "Advanced Voltage Regulator Module". You can find that thing working in ATI HD4870 and X2 GPU's power circuit. There is no need for hardware modifications to deal with Vdrop. Now you can do it "on the fly" in BIOS or in Windows monitoring application.

    Hi, so do you see a benifit on the motherboard, i noticed that the mosfets seem to be gone and less heatpipes, but will it be noticible for overclockers.

    thanks for the info...

    People still actually buy nvidia chipsets? :nutkick:

    Before the fanboys tar and feather me,;) t'is just a joke.

    I still don't get it what is the difference between these digital and (let's call it this way) "analog" PWMs. I am a second year electronics student, during study we mentioned PWM voltage regulation circuits and they are already digital power switching circuits. How come digital voltage regulator becomes more digital?

    EDIT: I think the only difference between "analog" (normal) and digital PWMs is the switching frequency. Due to decreased filter capacitors size it seems that digital PWMs use much higher switching frequency.

    What they shouldve done in addition to that is replace that crappy NB fan and improve NB cooling.

    That's a very valid point actually ;)

    it still runs hot, if i had that board i would've replaced the whole heatpipe with thermalright or swiftech chipset/mosfet coolers. Thats why i think evga shoul've improved cooling capability, not just the fan.

    lol I agree... most often XfX just take an OEM nVidia product then slap a sticker and add warranty on it. Evga on the other hand revises reference design.

    I wanted to step up to the FTW and it is not one of the options I get from eVGA:ohwell:
    They want me to go to the Ultra 790 for about 90 bucks extra.:mad:
    Is XFX a good MB maker?

    Beginners with cash = Alienware....then signup on a tech forum...learn from the mistake of splashing money at Alienware...learn what FTW means...

    I have an Alienware tower .i.. ; P ..i. everything bolts great in it.

    Ofcourse I bought the least expensive setup because all I wanted was the tower, lol.

    But why would I want a bugged out intel board? They can go to hell.
