Will a Corsair HX650W PSU be able to power a SLI 660Ti System?

I was wondering If I will be able to have two MSI 660TI's in SLI using a HX650 PSU...

The Build:
Intel i5 4670K
CM EVO 212
MSI z87 GD65
8GB Corsair Vengeance
MSI 660TI(s)

I don't really want to have to send back my current PSU and get a larger one, and go through the whole return process. I also don't plan to OC the CPU, Ill just let the Turbo Boost do its thing. So Will the 650W be able to Power this system, and efficiently

  1. Best answer
    Yes. The minimum recommended is 450W (system with one card) + 150W (max for second card). You have 650W.
  2. Answer at bottom of page

    Thermal and Power Specs:
    97 C - Maximum GPU Tempurature (in C)
    150 W - Maximum Graphics Card Power (W)
    450 W - Minimum System Power Requirement (W)5
    Two 6-pin - Supplementary Power Connectors

    So 450 for system w/ 1 card + 150 for 2nd
  3. Guru3D recommends a 700 watt power supply on a high-end, power hungry system. They tend to overestimate to account for some overclocking on the CPU. You also have a high-end professional series PSU capable of exceeding its power rating. You should be fine. Just be alert to any oddities that may indicate insufficient power.,7.html
