Will 900w Power SLI 680s

Hi, I am building a computer and I was wondering if the PSU I selected would power 2 GTX 680's SLI

Here is a list of all the parts I've selected for my build:

The PSU is the Antec HCG-900:

Here is the card I plan to use in SLI:

I don't plan on overclocking right away, but there is a possibility of minor overclocking in the future.
Will the PSU be sufficient for that build? If not, could you please recommend a PSU to me?

All help is greatly appreciated,

  1. Should be around 700-750W peak so a 900W PSU should be fine for mild overclock.
  2. Plenty... rails look good too minus having 4 of them.
  3. I wouldnt be suprised if it could power 3, as guru3d recommends a 900w for 3 way sli

    though i have to note, the antec hcg 900w specifically is the one antec psu that failed hardocp's test.

    Hi there your PSU should be fine however i wouldn't risk it as that psu has failed some tests i recommend you get this instead it's better and has a seven year warranty

    Here is Guru3D's power supply recommendation:

    GeForce GTX 680 - On your average system the card requires you to have a 550 Watt power supply unit.
    GeForce GTX 680 SLI - On your average system the cards require you to have a 750 Watt power supply unit as minimum. If you are going to overclock the GPU or processor, then we do recommend you purchase something with some more stamina.
  5. The HCG 900 is perfectly fine! It's seasonic made and will run up to 3 GTX 680's.
