a b ) Power supply
September 7, 2013 6:44:58 PM

Hi-
Here is my situation. I am building a computer, and right now only have the case. After I hooked up the fans (1x 120mm, 1x 80mm, 1x 140mm), the computer wouldn't start. All the fans would make about 1/4 revolution, and that is IT. I know that it is the PSU because it's only a $20 400w supply. I am going to need a new one anyway, due to the new components that I am looking at, but I wasn't expecting it to be this soon. The current estimated wattage is 313w, but with 2-way SLI it comes to 513. Will a Corsair CX Series Modular CX600M be enough to have 2 GPU's later on? Or should I get the 750w one? Again, I need to get just the supply this week, and the other components will come sometime after Christmas.

I would avoid the CX series

Sizewise ....find ya card here....

http://www.geforce.com/hardware/desktop-gpus

Click on it and then select "Specifications" on left

Scroll down and add the "Minimum System Power Requirement " (covers system + one GFX card) and "Maximum Graphics Card Power" (covers 2nd card) together for system requirement on non overclocked system

Thanks for the help. Gor my GPU, i need a 8pin and 6 pin connector to power it. Are there any modular PSU's from seasonic with those connectors? Also, would 600 watts be enough power for 2-way SLI?

In the post above yours I used a 650 Ti Boost as an example... you can use that site for all cards

450 watts for system w/ 1st card + 134 for the 2nd so according to nVidia ya need 584 watts minimum

So that would be a 650 if not overclocking anything, a 750 if ya are.

If it's a 770.....

600 + 230 = 830 minimum .... bigger if overclocking

As for the modular thing.....modular provides no advantage and some disadvantages. No sense in making a cable modular if it absolutely must be used. All it does is add another failure point an extra resistance / cost.

Most quality PSUs are what's called semi-modular. All the cables that absolutely must be used are hard wired....all the optional ones are modular.

Look for an Antec or Corsair in the 750w range at Best Buy.They don't carry too many good units.
