2 way SLI / PSU

post #1 of 3
Thread Starter 
I am about to proceed with a purchase of a second gtx660 card, now do i need to buy a psu at the time, would like to know so i can i save on shipping. my current psu is 520W.
My opinion is that i will be stretching my power some what if dont upgrade, but how far should i go plus to allow for overclocking etc. ya reckon 750W would be enough ?

I see 600W is recommended for 660SLI HERE
But if your 520W is a good quality one, it may be able to run it. Is it the Antec HCG? Personally, I'd give it a try if it is, that psu is very well made and might have enough juice to get away with it.

Edit: I see now that you are also overclocking, yah, maybe the 520W would be a little too little. rolleyes.gif
