New To Overclocking help!

Above, a chart of relative power consumption. Again the Wattage shown is the card with the GPU(s) stressed 100%, showing only the peak GPU power draw, not the power consumption of the entire PC and not the average gaming power consumption.

Here is Guru3D's power supply recommendation:

GeForce GTX 670 - On your average system the card requires you to have a 500~550 Watt power supply unit.
GeForce GTX 670 2x SLI - On your average system the cards require you to have a 700 Watt power supply unit as minimum.
GeForce GTX 670 3x SLI - On your average system the cards require you to have a 850 Watt power supply unit as minimum.
Remember, if you are going to overclock the GPUs or processor, then we do recommend you purchase something with some more stamina. The minute you touch voltages on the CPU or GPUs, the power draw can rise real fast and extensively.

Taken directly from your 2nd link. I made my recommendation........I'm done

Alright Awesome! thanks for all the help and recommendations! i quite honestly had no clue there was so much in a PSU lol

alright well as much as i would love to get a good quality PSU, my budget just dosent allow me. after all, i still need to buy other stuffs. so im bricked between these:

Rosewill RP600V2-S-SL 600W ATX12V v2.01 SLI Ready Power Supply - Newegg.com
CORSAIR Builder Series CX600 600W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply - Newegg.com
Rosewill Green Series RG630-S12 630W Continuous @40°C,80 PLUS Certified, Single 12V Rail, Active PFC "Compatible with Core i7,i5" Power Supply - Newegg.com
RAIDMAX HYBRID 2 RX-530SS 530W ATX12V V2.2/ EPS12V SLI Ready CrossFire Ready Modular Power Supply, New Version with Build-in LED Fan On/Off Switch - Newegg.com

the 450W one posted earlier, i dont think 450W will be "future proof" like i dont think that i will be able to upgrade parts and add fans etc later one without it stressing. i could be completely wrong tho.
