Ok, I am looking to build a desktop computer again, but I have been out of the game for a while. I am seeing a ton of 400-500W power supplies, but when I left that was nowhere near enough juice.

So, the system that I would be building would be an AMD Athlon II X4 640, or a Phenom II X4 955BE, one DVD RW, one HDD, and a single HD6870. How much power am I going to need?

Forgive the noobishness, when I left, I had had a Core 2 duo E4300 and a 3870X2 and a 750W power supply.

Shouldn't need much more than what you had. A good 750W PSU should push all that just fine.

Been hearing conflicting stuff. Some say a quality 450W is all that system needs.

I've never used less than 700W for any system in the last 5 years. I'm sure it would be fine.

Welcome back to the game. :p If you were planning to keep everything stock, a 400w PSU would be fine. A 500w unit will give you more headroom for moderate overclocking. If you think you'll add another video card down the line, a 600w model would do the trick fine.

This all of course assumes you'll use a PSU that's truly good for its rated output.

Thanks. My laptop is nice, but starting to chug, so it gets donated to my sister and I get a new desktop. Looking to OC some, nothing insane though.

Was looking at this:
PC Power and Cooling Silencer Mk II 500W High Perf...

or this
OCZ ModXStream Pro 500W Modular High Performance P...

I was just recommending that OCZ model to someone else earlier today. A nice deal with the MIR.

Yup I like OCZ and Corsair, neither brand has ever had a failed unit so far in my experience, including rigs I've built for others. I don't know about others, but I have never received a single rebate from OCZ. YMMV

Been hearing great things about the latest Enermax PSU's. I'm personally a fan of seasonic, xfx, corsair, or anyone who uses seasonic guts lol. Also pc power n cooling, silverstone, antec, thermaltake, etc, etc, etc, etc.

Check reviews here and at HARDOCP to find EXACTLY what you need and want.
