PSU powerful enough for SLI GTX580s?

SO recently I've come into owning two EVGA GTX 580 1.5GB versions, and I have an SLI bridge and everything. The only thing I'm missing is an additional PCIE 6+8 pin connections but my PSU is modular so I can get that. The question is will my PSU be strong enough to support this setup? Here is my PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817152036 I currently have an FX-6100 CPU stock 3.3ghz running at I believe 1.41v (which i could lower if needed), 8GB ddr3 @ 1333mhz @ 1.5v, 1 DVD RW drive, 4 120mm fans, 2 80mm fans, one 7.2k sata drive, stock CPU fan and everything at stock speeds. Here are the more specific specs of the power supply.

Honestly I feel like It would work but that it would be a very tight squeeze with the power. It's worth noting that I've had this PSU and used it regularly since early 2012. If needed I could unplug the DVD drive and disable the 80mm fans to budget my power a little bit better. Any help would be greatly appreciated, thank you!

  1. It's a very poor quality power supply.
  2. Best answer
    I would want at least a decent 850w.
  3. Trying to power 2 580s with that poor quality PSU is likely to end badly.

  5. Yeah that EVGA one would definitely do alot better, but honestly I feel like the 80 bucks would be better spent towards a CPU upgrade or something, I guess I'll just ditch the SLI idea. I feel my rig is falling apart :(
  6. Sometimes it gets to the point , where it's time to build a new one.

    Well I appreciate the help, I'll probably just sell the 580s along with with 560ti and that might get me somewhere in the ballpark of getting a cheap rx480 or something. And perhaps invest in an fx8320, but we'll see
  10. Skip the FX they are EOL look into an intel 1151 \ i5 setup.
