as a forewarning i'm only somewhat computer saavy and the terms i use may pain you.

I wasn't sure where else to put this, but:

I have this psu: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139015

along with this liquid cooling system: http://www.newegg.com/Product/Product.aspx?Item=N82E16835181019

and this gpu: http://www.amazon.com/gp/product/B004KZHRAM/ref=oh_details_o08_s00_i00?ie=UTF8&psc=1

i'm currently running into an issue where (if you look at the psu), the 2x8 pin socket is where i've been plugging in the fan/radiator for the liquid cooling and one of my pci-e cables (splits into two which i plug into both parts of the gpu), however in order to SLI, i believe I need to have another 2x8 pin socket to plug in my other gpu (same exact model as before). am I allowed to use another socket or is there a splitter of some sort I can use to plug in both 2x8 pin pci-e cables? i'm at a complete loss here.

When you say allowed... do you mean "will the card function using another 2X8 slot? (PS, we call them 8 pin). If that is what you mean, then yes, it iwll work fine. The GPU does not care where the power comes from.

well I only have 2 of the 8-pin sockets and one is being used by my first gpu, and the other is being used by the radiator for the liquid cooling. So, they're both being used up, and I can't unhook them since they're both pretty vital. I have another 8-pin psu to pci-e x2 cable, but seeing as how I don't have another 8-pin socket, I was wondering if there was any way to work around that.

I imagine i need something like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16812706022
but instead of 2 male, I would need 2 female.

I hit this issue myself. Try looking on EBay for other Corsair cables. They should be the same pattern. Look for one with 2 8 pin GPU connectors on the same PSU cable. I got stuck making my own.

I've tried looking into ebay, amazon, newegg, etc. no dice. I've been suggested to look into a splitter for an 8-pin male to 2 4-pins, and use 2 4-pin to 8-pin converters.

ok, so like i said, i'm not terribly computer saavy, but to break it down step by step (because i'm always afraid of messing something up):
1.you're saying get something like that, but better quality.
2.plug the 8-pin into the psu
3.get 2 4-pin molex - to - 8-pin adapters and plug them in
4.plug in the 2 8-pin males into each of the adapters
5.connect each 8-pin pci-e leads into the gpu

so essentially it'll look something like:

psu--> 8-pin male to 4-pin molex y splitter-->4pin molex (x2)--> molex to female 8-pin converter(x2)-->male 8-pin to gpu (x2)

Your psu has

1 x Main connector (20+4Pin)
2 x 4+4-Pin ATX/EPS 12V
8 x Peripheral
12 x SATA
2 x Floppy
4 x PCI-E

You should have the 24 pin power to your motherboard main power
then 1 of the 2 2x4pin eps power for your cpu which will either take one of these if your mobo has 4pin or join 2 to make 8 if it is 8pin ( power connector above your CPU on top of the motherboard )
Then you have 4 pcie 6+2 pin cables which will power both graphics cards
you can plug the h70 fan cable into a fan header on your motherboard or a get molex to 4pin/3pin ( Not sure what fan cable is ) to power cpu cooler radiator fan
the pump i would plug direct into molex rather than pwm header on motherboard ( molex to 4pin 12v )
you have more than enough cables , that PSU is a little confusing , this will help with the 6pin x4 for your graphics cards

the only thing you will need to get and that is personal preferance is molex to 3/4pin fan adaptor unless you plug fan into a fan header on the motherboard
and or molex to 4pin fan adaptor if you are going to power your pump with direct 12v instead of connecting it to the pwm fan header on the motherboard

just the one it's, by default an 8-pin, hence my using it directly into the power supply

edit: upon further inspection, i'm using a cable from the power supply (honestly don't remember what it's going to and i don't quite care to start pulling cables out to find out) that has 2 4-pin molex female leads. so, i started trying to look into a 4-pin molex male to 8-pin female converter and i'm not finding anything. not quite sure if i'm just not typing in the correct search terms or what. anyone mind helping me out? also, theoretically this should work, right?

edit 2: now if i were to use this, would it suffice? going from one of the female molex leads that i mentioned above to power the gpu or any other 8-pin male. http://www.ebay.com/itm/8-Inch-Molex-4pin-Power-Splitter-Y-Cable-1x-Male-to-2x-Female-/141173362046?pt=US_Power_Cables_Connectors&hash=item20de968d7e

or alternatively, using the molex idea still, i can connect 2 molex-to-pcie converters to my gpu, right?

and if it does work, it wouldn't kill the power to any part of the system, right? everything would just draw the amount of power it needs?

edit 3: welp, i'm an idiot. what i've been calling an 8-pin, as i took a closer look and started actually counting, is a 12-pin (2x6). not sure if that changes anything.

Okay so, I've been wondering, is it possible to get a F-F pci-e cable? I was thinking that I can just plug a female 6-pin into the psu, and it looks like the gpu's intake is male so I'd need another female piece, then repeat, but I can't find anything.

Also, on that note, I think I'm misreading male/female on some of these. I need something that goes into the psu, and the same gender of connector lead to the graphics card. Seems like sometimes I find a female and they call it male, and vice verse.

You mean male? Male is the "plug" and female is the "socket".

for example: http://www.newegg.com/Product/Product.aspx?gclid=CLLQva73q70CFewRMwodXEIAFg&Item=N82E16812198032&nm_mc=KNC-GoogleAdwords&cm_mmc=KNC-GoogleAdwords-_-pla-_-Internal+Power+Cables-_-N82E16812198032&ef_id=UkZ2agAABOdPzi-a:20140324194414:s

i was looking at it as the 4-pins on the left as the male and the right one as the female. I'm also curious about this: if i could use the cord i have (still not sure of the name of it, it's 2x6 from the psu and it plugs into the graphics card directly via 2 pci-e connectors), take the pci-e connectors and find myself a y-splitter from the pci-es to another pair of pci-es

edit: maybe something like this - http://www.frozencpu.com/products/8251/cab-147/6_Pin_PCI-Express_to_Dual_PCI-Express_62pin_Y-Cable.html?tl=g11c413s427&id=YaY3Dh6A

You could....I don't think that it would matter.

I don't understand why you are still chasing cables,
like i said your power supply will power everything you need to power including both cards and your psu has all the cables to do it ,
it is a shame though , it would take you less than five minutes to change cables as you have a fully modular power supply , i even provided you
with a video to show where your cables plug into , if you still want to get more cables then i believe it is a waste of money but by all means
go ahead , good luck , as i said earlier if all you have left to power is your graphics card then i would get two molex to 6pin pcie cables,
but your psu already has 4x6pin pcie cables for your cards so its a bit pointless IMHO
