First time building PC. Help me... i'm scared and its dark and smells like feet

Up until I stumbled across Tek Syndicate I didnt really even know what most of the parts inside of the computer did or how they interacted with one another. After watching for a while know I would really like to try to build a new computer because the one I currently have is shit. Sorry if some of these parts dont make sense this is my first time. Suggestions are appreciated but basically I want to know. Will this PC work?

tl;dr: Will this PC work?

New Parts

Motherboard: GIGABYTE GA-970A-D3

CPU: AMD FX-8120 Zambezi 3.1GHz Socket AM3+ 125W Eight-Core

Memory: G.SKILL Ares Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)

Video Card: ASUS HD7770-2GD5 Radeon HD 7770 GHz Edition 2GB 128-bit GDDR5 PCI Express 3.0 x16 

Scavanged Parts

Power Supply: Sunbeam PSU-BKS580-US 580W ATX Power Supply - OEM

Storage: Seagate Barracuda ES ST3500630NS 500GB 7200 RPM 

Optical Drive



I would personally buy a new power supply so I know its a good trustable brand with a single 12 volt rail.


If you spend $40 more you could get the new Fx-8350 4.0 GHz

Uses? if gaming this could be much better, if video editing its good. We need to know the prices, so use that.

Its for gaming mostly.

Yeah I agree I'll probobly get a new power supply at a later date.

If I manage to grab 40$ ill take your advice and definetly go for that but its stretching my price range currently.

What's your price cap?! This thing could be alot better for gaming.

Bout $500.

The PC doesnt have to be a GOD. Basically anything will be vastly superior to what I currently have. And its sort of more about the experiance of building my first Pc.

definity go for this. much better for gaming, and i would definately recommend getting a better psu, that thing is a ticking time bomb.

Yeah when I started to learn about power supplys I looked at mine and thought. Oh shit...

Heres a much better one

If its for gaming:

You dont need such a big cpu so cut down the cpu to an FX 4300

You dont need more than 8gb ram so change the ram to 8gb 1866mhz

That psu looks like a firehazard get something like a Corsair Builder 500W

That gpu is allright but with the $50 saved on the cpu you should be able to get an HD 7850 get a 2gb one if you can afford it.

Im really into this one.
