I found some forums where people say you can't, so I want to make sure because on the back of the box it says ''Ready for any SLI configuration''. I have a Cooler Master GX 650W. Nothing on my computer is overclocked. These are my computer specs: CPU INTEL I5 2500K 3.3GHz ASUS Sabertooth P67(REV 3.0) EVGA GTX560 Ti Maximum Graphics Edition CoolerMaster GX 650W Corsair Vengeance 2gx2 1T Sata6.0 HD LITE-ON DVD Burner

I am by no means one of the guru's around here, but I think you will be told by others that CM PSU is not very good. If you want to go SLI you should replace that PSU. That doesn't mean you can't , but I believe your cards/ system would be under powered.

Do a Google search for reviews of your unit. I would say it is questionable how well it would handle SLI. It is not the highest quality unit. This review here indicates you probably need about 700W for SLI: http://www.guru3d.com/article/geforce-gtx-560-ti-sli-review/14. Probably a good 750W or 850W PSU would do the trick without breaking the bank.

I believe it is a single rail 12v or something like that. Maybe Im wrong. Still a nooby to the PC world

owentheomen get a single rail psu The more rails the better, adds stability. Altho I suppose there may be a point where too many rails is bad? I dunno, I have 8 and that seems to be the sweet spot right now for SLI setups. Now for me to get a SLI setup : P

I dunno, I have 8 and that seems to be the sweet spot right now for SLI setups. Now for me to get a SLI setup : P My AX 1200 would beg to differ. The defining difference between most 'single rail' and 'multiple rail' units is how the output is divided not how the output is generated. You can use the exact same source and create a single rail unit or a multiple rail unit. So one design, isn't inherently more stable than the other. Some like multiple rails because the output on each rail is limited and has protection against over current/over voltage. Multiple rails require you to pay attention to how you connect to each rail so you don't overload one. A singe rail design on the other hand, has it's full output available on every output. So, there isn't a requirement to balance loading on the rails. Folks will argue pro and con for each. Functionally between each, for high quality units, it's a matter of personal preference not real world performance.

Those making single rail units will imply theirs are more stable because 'one big fat rail' is better than a bunch of smaller ones. The important things to pay attention to are, voltage regulation and ripple under full load.

EliteGeek91 diegorubeus what do you guys think about this psu: i think im gonna get that one. also it would work for him i think. That's good. Here's two more for alittle cheaper, but not for sure exactly which is best. That's just the bronze certified edition, or I should say revised edition.

i think the HX version is better. it a little more expensive but it's semi-modular and the modular cables are flat. seems like a good unit with 70A on the 12v+ rail and it's 80+ silver.

SLi ready usually doesn't mean any SLi pair you want, so you have to look at the specs to be certain. nVidia's website states each reference GTX560 Ti draws 170W (14.1A at 12v), the slight frequency bump of the Max Ed isn't that much extra power, so add another amp and make it 15A to be safe. Two makes 360W, or 30A at 12v, just for the video cards. The CPU is around 90W* also drawn at 12v. So the total for just these components is merely 450W, or 37.5A -- your PSU's 52A covers this pretty well. It is unlikely the rest of your components draw more than the difference on the 12v line to make a difference, so your power supply just happens to be in the green. If you get to overclocking the CPU to 5GHz, you double your CPU power requirement and the grand total ends up at 45A draw for 12v, or 540W. Guess what, you are still meeting the minimim with your power supply, as I highly doubt the rest of your components draw another 8A. Your fans and drives have their power specs on their labels, if you want to take a look. The Cougar Point chipset that is in LGA1155 board is just a glorified southbridge and dissipates less than 6.1W of heat (that's what TDP means, it is just a category), so it may draw around 7-8W of electricity, but not at 12v. Respectfully to others suggesting more than 650W since they still provided useful information to others, it doesn't apply to you. I just showed your what you could expect and the kinds of research you should be doing to give yourself the advantage. * Recently a preview pit the AMD FX-8150 with i7-2600K revealed the power draw of the 3.4GHz quad with HT at 93W of electrical power draw (not the heat value, which may be around 80W) at stock. 2500K is only slightly slower, so I made a call at a 90W draw stock. I have a link in my sig that can estimate the increase in wattage levels for an overclocked CPU, check it out when you can.

I respond with many expletives followed with why would I want to see the system power usage and not only the cards themselves. Sorry for overlooking that technicality. I shoulda checked more than one source, my bad. Here is another with ONLY the video card's power consumption. http://www.bit-tech.net/h...tx-560-ti-1gb-review/8 Unless there is somethin else I am missing, he cant run two GTX560Ti's in SLI.
