Get a Hyper 212 Evo cooler if you are overclocking, otherwise the stock cooler will do fine for its intended use, followed by a good TIM application.
With your system at full load, it barely pulls 300W on the wall so 430W PSU in more than enough.
You have to log in first into your web GUI, then set the password to which SSID you're using. To do that, enter the IP address of your default gateway in the browser and it will prompt that you must enter the necessary credentials. Use WPA2 for encryption.
My first cooler was H80i and it was terribly loud at full speed. It also performed bad so I sold it. I was getting temps like you do with my 4670K. Settled for a PH-TC14PE air cooler, so much quieter.
Try re seat the cpu block at least three times.
Something I think is wrong, maybe re seat cpu block or water not going through block and rads. I have a 4670K overclock to 4.5GHz w/ 1.28Vcore and I'm only getting 61C max at gaming full load using a PH-TC14PE air cooler. 4770K will have to add ~5C because of HT.
I would rather get a GTX 780 than two 770 right now. 650W is plenty for a single GTX 780.
