Here's my setup
CPU - Intel i7 2600 @3.40GHz
GPU - EVGA NVIDIA GTX 660 Ti
RAM - 8GB (Speed: PC3-10600 MB/sec,Type: DDR3-1333)
Motherboard - MSI Z77A-G45
PSU - OCZ-ZS650W-UK ATX 650w PSU
HDD - 2TB (Interface: SATA, Rotational Speed: 5400 RPM)
Blu ray disk drive (not sure about specs)
Case- Zalman Z11 Plus

Can someone tell me how I'd go about setting up a 2nd 660 Ti, in as much detail as possible.. my first time dealing with SLI. :p

I'm going to buy a SLI bridge connector for £5 ( http://www.ecrater.co.uk/p/17710326/asus-long-flexible-...)
but what other cables do I need?
Someone said I need to buy these : http://www.amazon.co.uk/Startech-com-Express-Power-Spli...
and someone else said I don't need those, he said I should just use the 4 pin power molex adapter that came with the card - http://www.playtool.com/pages/psuconnectors/pcie6.jpg

What do I REALLY need?
If you could tell me what plugs into what and a simple quick installation guide that would be awesome!

Yeah I already have 2 of them which came with my 660 ti i bought a few months ago!
So I don't need the other 6 pin adapter?

No , use the ones that came with the card.

Your other ti is being powered by the PSU pcie cables , so you shouln't need anymore besides the ones you already have. 2 for the new card.

That PSU isn't the best so you might want to upgrade in the future , to a Seasonic ,XFX , Antec.

Thank you so much! that's cleared so much up for me!
I will upgrade, but not yet :)

Just one more question, where do I plug the 4 pin molex adapter into? Obviously the 6 pin will go into the graphics card but what about the 2 4 pin ends? Do they go into one of the psu cables?

This should be the last question..
So straight into these? http://i.imgur.com/Tk1yTMI.jpg http://i.imgur.com/71HG4wZ.jpg
if you're wondering why they're so bulky it's because my case fans are also connected and they supply an extension :p


..So, straight into that socket then the 2x6 pins on the other end straight into the GPu right?
There shouldn't be any less performance because of all the adapters and fans should there?

Sorry man I'm so confused, I've never set up a GPU before, never mind 2, my dad did the last one haha!

So was what I said right or wrong? Those fans were plugged into cables from the power supply?

Will do, before I make any other major upgrades :)
Thanks for being patient with me too, I'm not the best of PC people :p
