GTX680 SLI with Corsair TX650 V2 ?

Can I do GTX 680 SLI on a TX650 V2 ?
3570k @ 4.4GHz
16GB 2400MHZ
Rampage Extreme
2TB

Will I get 100+ FPS @ 1080p 120HZ in latest games?
Thanks


EDIT: My unit is the SeaSonic Built :) NOT CWT

  1. No you can not SLI with two different cards they must all be 680's or 650's.
  2. The power supply isn't really going to affect your frames, its going to determine whether or not your gonna be able to power certain setups, and honestly a 650W i feel would be cutting a bit low for a sli 680 setup.
    Also the framerate you receive is also going to be affected by your cpu and RAM not just your video card setup.
    How much Ram do you have?

    check it out ^ you might be pushing your PSU a little to far depending what else you have hooked up to it. i would jump to 700+ watts especially if your overclocking.

    the 650 is his power supply not the other card...i almost misread it too ;)
  5. For a system using two GeForce GTX 680 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 750 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 53 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors or two 6-pin and two 8-pin PCI Express supplementary power connectors depending on brand and model of the graphics card.

    Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated @ 45°C - 50°C ambient temperature, is the most important factor.

    Overclocking of the CPU and/or GPU(s) will require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

    Your Corsair Enthusiast Series TX650 V2 (SKU# CMPSU-650TXV2), with its maximum combined +12 Volt continuous current rating of 53 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is borderline sufficient to power your system configuration with two GeForce GTX 680 graphics cards in 2-way SLI mode. It is deficient by two PCI Express supplementary power connectors.

    I wouldn't recommend it. Get a properly sized power supply unit with the appropriate number and type of PCI Express supplementary power connectors.

    yeah i didn't bust out the numbers but found the same looking into it when you posted. it seems like a big stretch for your PSU. why risk your whole build, just get a better PSU.
  7. MY kill-A-watt saying im just pulling just below 300watt while BF3
    add another 200w for the 2nd GTX680 Should be safe @ 80% PSU usage, right considering its no pico
    beside when its idle on 10% rouhly 70watt sounds easy on the bill right?
  8. your pushing your PSU but i think you a hair in the clear. I would think about a new PSU soon though. capacitor wear rate will certainly go up with the extra current draw.

    That reading sounds low enough that I wouldn't believe it, I WOULD NOT put dual 680s on a 650W psu. I Run a 670 and wouldn't even think of adding another without a bigger PSU.

    If you don't do anything crazy like running FurMark you may be able to get by.

    You'll have to use a couple of dual 4-pin Molex peripheral to PCI-E adapter cables though.

    honestly i have to agree....while i believe its possible...its a bad idea. if it were my rig i wouldn't do it either.
