I just need a parts list to liquid cool two 770s and my CPU this is what I'm getting so far
-Bitspower G1/4 Compression Fitting (1/2 ID x 5/8 OD) x12
-EK Supremacy Universal CPU Liquid Cooling Block
-EK Dual Bay Reservoir (Pump Installed)
-EK 240 Rad
-EK 120 Rad
-EK Ekoolant
-Tubing
-120mm fans for rad x3
-EK Backplates for the 770s
-EK Geforce GTX 770 Liquid Cooling Block x2
-EK G1/4 Stop Plug x4

My loop I was thinking of was Reservoir/Pump>240Rad>CPU>120Rad>GPU>GPU>Reservoir/Pump

Have I forgotten anything? Also are the parts here enough? And how do I connect the SLI GPUs?

I would look for a different pump, EK's Jingway models dont have that many reviews and are a bit offy on performance given their price. I would be looking at a D5 variant.
Also bay-mounted pumps I would avoid, there's no room to decouple (pad against vibration) in that space and it will let off noise.

A killcoil is a strip of silver you put in the loop, basically makes the water toxic to bacteria/algae so nothing grows in there. A Biocide does the same but is an active chemical, most of them use Copper Sulfate. I use a Killcoil as its the easier solution IMO, you dont have to re-apply, just drop in the res and make sure it cant get sucked into the pump.

Draining the loop means draining the loop. If you ever have to drain the loop, how...

I reckon you going to need more rad space than 360mm for what your trying to cool.
What pump is that?
Dont bother with coolant, Distilled water plus a Killcoil/Biocide will do fine.

Have you thought of how your going to drain the system?
SLI fittings are usually used to connect graphics cards in a loop, though EK tend to offer bridges for their blocks.

The pump was an EK Dual Bay Reservoir w/ EK DOP 2.2 Pump Installed.
Can you explain what a KillCoil/Biocide is (I'm a complete noob to liquid cooling)
and what do you mean by draining the system? Also could you link me a bridge or a video on how to connect liquid cooled SLI GPUs

Sorry If I'm coming off retarded T_T

Draining the loop means draining the loop. If you ever have to drain the loop, how do you plan to do it? Its worth thinking of that now. Also on how you will fill up the loop.
Something like this is used to connect cards in SLI/Crossfire.

Though EK with their blocks also offer things like this.

I would go with the first option given its compatible as its a more flexible piece, it can be used for more than one purpose unlike the dedicated bridge.

Find the lowest point of the loop, stick a T-Line off of it.
