Can I SLI these two cards

[Kriseagle]

I just ordered two Galaxy gtx 660 O2gb versions video cards ( http://www.newegg.com/Product/Product.aspx?Item=N82E16814162122 ) I'm wondering if my power supply can take it. Thanks for the help in advance here is my specs

M5a99x Evo
Rosewill Challenger case
amd 8gb ram"
Corsair 600 watt power supply (CX600)
AMD FX 8120

also if not any recommendations on a PSU 100$s or so would be nice.

Yes that psu has 2x6+2 pin pci connectors and enough power for 660 gtx sli

Let's say that it doesn't have enough power can it harm anything, because a guy told me that it can harm my computer because it wont be able to hold it.

If its not enough power then it probably wont boot, or one cards inputs wont show anything, or something silly like that.

That being said i would definately get a bigger PSU. Even if it does run the two cards, it would be close to its max output. I would rather have a 750w+ psu running at 75% capacity, than a 600w running at 95% capacity. Your PSU will last longer that way, and leave less of a chance for a power surge to fry system parts in the future.

That psu has a single rail +12v@46A which can draw about 573W, two 660 gtx (non ti) oc full load will give about ~250-280w, you'll be fine.
