✔ Best Answer
Make sure to get a decent name brand power supply. The fact that you call it "SMPS" tells me you're probably from India. Based on other posts about power supply availability in your country, there seems to be problems finding quality units. Look for the following when checking the specs:

- 80 plus efficiency certified
- single +12v rail with high amperage (80A+ for a 1000W unit)
- +3.3v & +5v rails rated at no more than 25A
- active PFC
- good warranty

Figure close to $200 (over 12,000 rupees), possibly higher.

Your graphics card says it can draw up to 300Watts and your CPU is listed as 130Watts, that's 450Watts for your 12Volt rail or 37.5Amps. Round that out to 40 Amps on the 12Volt rail for nearly everything and the Corsair CX600 puts out 46 Amps on the 12Volt rail. In short, Yes, the 1000 Watt Corsair power supply and even the 750Watt model should be more than enough power for your system. The 1000 Watt model could handle two of these cards with it's 83 Amps of available power.

Edit: Sorry, I just reread the question. Yes, you can run 2 of these in SLI on that power supply.

You have to be a little bit crazy to keep you from going insane.
