I've been looking at 3 different ones, and I can't choose.

That one is $9 over budget, but has great reviews.

Great reviews on this one as well, but 100w less than the other.

http://us.ncix.com/products/?sku=35456&vpn=OCZ700MXSP&m...
Right in the middle, and is modular. Have heard that cords are short, so with a Haf 912, I'll probably need to get an extension right?

I've checked everything, and at most, I'll be needing less than 600w. But the deal is just too much to give up easily.

So, which do you think? If you have another PSU in mind, I'm all ears.

Will be running an i5 2500k, 1 500gb hdd, a regular motherboard(AsRock), and a HD7950.

Looks like a good deal. 9$ out of whatever your whole budget is isn't much. 2 things to think about:

1) The psu is the only thing in your computer likely to damage other parts
2) It has a 7 year warranty. In 7 years everything else, even the case, will be obsolete.

You don't need 750w for that system, a good 520w would do if you don't plan massive upgrades. Any of the three you've picked are going to be better than 99% of what people have in the systems.

Atm, I don't have a big upgrade planned, but I may be going crossfire or sli in a year or so, so its always great to have that headroom

The ModXstream has insufficient power connectors for your planned SLI upgrade. Both the XFX and the PC P&C have are electrically sufficient with 53A on the 12V rails and sufficient power connectors. Both are good quality and I recommend either one for your use assuming you are definitely going to SLI. If you're not going to SLI, then I would recommend the Seasonic M12II-520: http://www.newegg.com/Product/Product.aspx?Item=N82E168... It's more than sufficient and is a great PSU; I'm using one for my more power-hungry HD 6950.

I need to know, with me having the HAF 912 Advanced, do I need modular? I looked inside, and the space behind the mobo is pretty deep

Modular is really a personal preference; it is easy enough to hide extra cables. The reason that I mentioned the M12II-520 is that it's such a great deal right now and it's a top tier PSU.

Looked more closely at Crossfire and SLI, and realize I don't really need it. But, I would still like to keep near 600w. What do yall think about this one?
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

The M12II-520 is higher quality, is made by Seasonic, and has the same amount of amps on the 12V rails....I would stick with it.

Am I being paranoid? If I decided to get an SSD later, would the 520 still be able to handle it? And can I get some good overclock on it? Sorry, I just want to make sure I don't screw up something.

A good kind of paranoid, but yes you're being paranoid. An SSD has a minimal power draw; less than 10W at max load. For a system with a single HD7950, the M12II-520 will have sufficient headroom for significant OC of the CPU/GPU.

the 520 is about perfect for your system

Don't tell me to do that one, as you have seen, I second guess my decisions quite frequently lol. I've never heard of that website, but they are apparently in Florida, which is quite close to me.

Not actually modular, that seems to be the one big complaint, but I have plenty of room behind my mobo to situate cables if needed.

They are both great psu companies, right?

The TPN is built by Seasonic
Provides a little more power
Is less expensive ( shipping may be less for you, I'm in NJ )
No brainer in my book

Its still $15 for shipping, but you are correct, is still cheaper. Little more power, very close to gold 80 plus.

The M12II-520 is around $3 more. Same warranty but the TP-550 gets you 5A more while the M12II-520 is modular....you don't really need the extra amperage or the modular cables so choose based on which mfr you like better and whether or not you want the modular cables or the extra amps.

To be completely honest you'll love either one and both are high quality; there is no bad/wrong choice.

Rugger, I'm going to go with your suggestion. And I believe Newegg is doing a free shipping thing with ShopRunner, do you know anything about that?
