Here's my build and I need to know the psu recommended. I want to save money.

Case
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
it comes with 3 case fans, so I'm trying to include that in the psu

ASRock Z68 Extreme3 Gen3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

Another 1tb hd, a dvd burner.

I want to be able to overclock to 4.5 at least and maintain it. I don't expect to desire sli or anything like that in the future. I figured 600w would be good enough, but I don't know a lot about ocing. Also, I noticed a lot of psu included in their titles that they worked with the sandy bridge. Anyway, you guys are great, and I appreciate any help you can offer. Remember cheap, but not crap, if that's possible.

There are other problems with your built to worry about before i get to the psu.
If you are going to stick with the 6870 your 2500k is an overkill. While being a good-ish gaming gfx card it will bottleneck your cpu and overclocking it is an overkill for the rest of setup. The 2400 offers the same gaming power and you can put the money you save towards more ram or a 6950 (i support both upgrades). If you choose the 2400 even stock will do but since i am no fan of downwards blowing heatsinks you can get a cheapo but sturdy CM tx3 http://www.newegg.com/Product/Product.aspx?Item=N82E168... .
Your ram is high profile, go to a low profile and 8gb. You won't need the z68 gen3 for what you describe either. No OC and no SLI/Xfire means that a mobo with 1 pci-e x16 will do. A ga-z68ma-d2h will do here. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Now that we saved some money, the 6950 http://www.newegg.com/Product/Product.aspx?Item=N82E168...
In the department of hdd i can only advise to either cannibalize one from a system, go to a local store see if they got stock prices before the floods or try a sales forum/ebay. Getting a caviar blue of 250 at this price is a mistake! That is the price you would get a 1tb FAST hdd.
Now that we reached the psu, a 600watts is good...

lol where were you a few weeks ago. Sadly I've already bought everything but the case and psu. As for overclocking, I wanted to overclock for other reasons besides gaming, so I hope that's still okay. I guess my next question is, since I've already bought everything but the case and psu, what would I need to get the full power of my 2500k? Also, will those psu be good for overclocking?

LOL where the hell did you get the notion that a 6870 will bottleneck an i5 2500k? it wont even bottleneck an i7 2600k -.-

The board... I kinda agree, but meh, if you bought it and dont want to return it for a better overclocking one, then its no big loss really :) 

And the ram, looks fine to me -.- by Low Profile i assume you mean one with shorter heat sinks right? he could just put the ram in the slots more towards the back :) 

and yeah bro, dont get a HDD now, i bought one about a month ago, samsung spinpoint F3 for 50-60 now its going for 150+

Anywho, yeah that build looks good to me :) 

As far as PSUs go i would get this model: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

If you need an aftermarket cpu cooler, grab the Hyper 212+ or the 212+ evo.... dont even bother with the TX3 you'll be happy with the extra 5 bucks you spent on the 212+

they will be perfect for what you need it. In fact you can drop it an inch since the 6870 doesn't have big power draw. If you don't plan on changing anything for a time a 430watt will do.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

It doesn't have a second gpu power cable so you will have to feed it from the molex extension.

Any of the 3 mentioned PSUs will do perfectly fine with OC. The only thing that should be noted is that if you decide to go replace your gfx card along the road the 450watt won't suffice. Also for xfire it won't suffice either. But if this is all you are going to spend for a good 2-3 years then i don't see the point in going any higher in wattage.

The case is more than fine ;)

Perhaps bottleneck wasn't a good expression to use. What i meant is that for a 6870 an i5 2400 is enough to run it at it's full potential and then some more. The cpu power demanded by the 6870 to run at it's fullest is a little bit above the i3 2100. I am looking at the system as a whole you see trying to have most of the components en-par and what i saw is that you have a killer cpu with an average card (that will play everything for a long time, no doubt), a killer motherboard, a nice set of ram that could be doubled in size for a small amount of money (compared to the whole) and a slow-ish and small hdd.
BTW i never suggested the TX3 for an OC 2500k, it was a suggestion for the 2400 who doesn't even really need it.
Your system will run fine for what you want it, i was just pointing out that one leg is shorter than the others.
