Just put together a cheap system and I made the mistake of buying a Rosewill PSU. After the second DOA unit, I got Newegg to give me a refund and I'm going to pick up something not quite as... junk. In the meantime I'm using an Antec Basiq 430W I stole out of another system. It works, but I haven't started overclocking yet.
What I've got:
AMD Phenom II X3 720, 4th core unlocked (we'll see how far I can take it on air)
Gigabyte GA-770TA-UD3
2x2GB G.Skill Ripjaws DDR3-1600 CL7 RAM
ATI Radeon HD4870 1GB (won't be Crossfiring; mobo doesn't support it anyway)
One 7200 RPM SATA drive, may get another eventually
5 case fans (3 with LEDs), DVD burner, and a handful of USB devices
I've had my eye on this:

Or the Seasonic unit on which it is based:

Supposed to have really good ripple suppression for it's price, but I don't know how much difference that actually makes.
I'm concerned that it might not give me enough overhead with overclocking. How do you calculate the extra wattage required by overclocking, given a known Vcore? Is it all on the +12V rail? I've been trying to find some hard numbers about how many amps my video card draws, but not much luck.
Any information or advice would be much appreciated. I'm doing my best to learn, but there's a lot of information to absorb.
