460 GTX SLI on GS600?

Hello,

I am planning on buying another 460GTX Cyclone for sli (battlefield :) )
I am just wondering if my power supply will handle it.

I got the Corsair GS600.

The calculator gives me a recommended 540 watt.
The GS600 delivers 600watt. Do i have to count in the efficiency of 80%? (which will leave it down to 480)

Besides that my specs are:
intel 2500k
ASRock Extreme 4
8gb (2 sticks of 4) RAM
1 HDD 7200RPM
2 Fans (Standard CM 690II advanced fans)

Hope someone can help me out.
Thanks in advance

  1. The 80% efficiency is how efficiently the psu delivers the 600w, not that it only delivers 80% of 600w.

    On paper it should run your setup but in reality I would be thinking more 750w with 4x pci-e cables otherwise its pci adapters.

    Are you OC'ing the cpu or cards at all?
  2. it will work since under a stress test you only 450w total system power, gaming would be lower. you will need to use adapters since the PSU only has 2 PCI-E power cables

  3. I am currently not overclocking the CPU. If i would do it it would only be till 4 Ghz. Thing is that i dont notice too much difference in performance. Graphics card would not be smart to overclock when theres 2.
    Thanks anyway, i think it'll work.

    By the way, i'll need the molex to PCI-e adapters?
  4. Thanks everyone for the responses.
    I was wondering if it would be recommended to get some extra case fans. I have the Cooler Master CM690II Advanced with the 3 standard case fans (Front intake, rear and top exhaust).
  5. Enermax and Scythe Slipsteam do some nice case fans.

    Good luck with setup, I would def suggest running everything at default to start with while you test system stability.

    +1 on the fan brand recommendations but 3 fans should be fine for that case
  7. Thank you all!
