long story short, i made a build:

ANTEC KUHLER H2O 620 WATER

16GB DDR3 2133Mhz RAM

ASUS P8Z77-V

AMD Radeon HD 7950 3GB

Intel i5 3570k OC to 4.8 GHz

now, being the complete noob i am, i don't even know if 750w psu can run this, can it?

Yes if it's a good quality one. Tho with a 7950 and your proposed high overclock 850W would be "safer" Never skimp out on the PSU.

What's the name of PSU maybe?
You know, even 650w bronze+ is enough for this build, though higher numbers give you opportunity to upgrade in future ( changing GPU or adding another for CfX)
Btw, the RAMs you've specified are better for graphic works than playing, so tell if you're going for apps like 3DSmax, Maya or even Photoshop and Lightroom, cause if you won't, then 1600MHz is for you, cause 2133 MHz RAMs wont give you anything more than 1600MHz gaming-wise. So you can save a bit money there.

He's going to OC the CPU, setting the base value for memory to 1600 and going up from there will give some head room to OC.

My question for OP is that since you are a "complete noob", how come you know about OCing and nothing about PSU?
Rule of thump for PSU is to go after quality (like what INSTG8R wrote), witch usually also mean a bit higher prize.

Take this if you are thinking to mount later two Monster GPU in place of that 7950 ; SeaSonic Platinum Platinum-860 860W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS PLATINUM Certified Full Modular Active PFC Power Supply if not is enough this ; Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply or this one Seasonic SS-760XP2 ATX 12V/EPS 12V, 760W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply.

Bro, you don't need to OC the CPU that much. 4,2 GHz is enough for your GPU. As for the power supply... you will use 653 watts at you peak time(full load) , so I recommend Corsair HX Series HX750 Power Supply — 750 Watt 80 PLUS® Gold Certified Modular PSU
