Is this too small?

I'm going to build a computer soon and wanted to know this. I was going to buy a 500w modular power supply until I came across a PSU which told me I needed a PCU around 650-700w for it. Should i go ahead and get one around 650-700 instead? (I'm thinking about 700 instead of 650.) If anyone knows of any good ones please go ahead and post them. (Also, if you plugged a system that was 700w rated and you used a 500w PSU instead, would that ruin everything?)

Specs:
EVGA GeForce GTX 660Ti

Nzxt Technologies Phantom Case

Western Digital Caviar Black 1 TB SATA III 7200 RPM 64 MB Cache Internal Desktop Hard Drive

Intel 330 Series Solid-State Drive 120 GB SATA 6 Gb/s 2.5-Inch

Gigabyte Intel Z77 LGA 1155 AMD

Corsair Vengeance 8 GB ( 2 x 4 GB ) DDR3 1600 MHz

Intel Core i5-3570K Quad-Core Processor 3.4 GHz 4 Core LGA 1155

It depends on what you want to do in the future really. I run a similar system to yours comfortably on a 500W PSU, however I will have to upgrade if I want to do SLI or crossfire (2 X GPU's) for example. Or if I bought a part that requires a lot of power.
So for now, you should be able to run it well on 500W, but if you want to upgrade a lot or to much more powerful parts in the near future, Id go for 600W to 700W PSU's :) 

Regards,
Dan.

Hi - Unless you are going to SLI 2 660ti's, you need only a quality 450w
unit(per EVGA & realhardtechX) for a system with one 660ti. There's no
harm to your system with a lot of PSU overkill, but it's a significantly
higher and unnecessary upfront cost.

I suggest if you feel you need more overhead than is already built in to the 450w,
then maybe think about 500-550w quality psu.

Quality brands: Seasonic, XFX, PC Power & Cooling, Rosewill Capstone series,
Antec, most Corsair's, Enermax, & a few others.

I kind of wanna get the ENERMAX NAXN 82+ ENM750AWT 750W. (Added more just in case I wanted to add a lot more things.) Is this compatible, and my final question, Is that a good PSU?

Enermax is good, but you don't need the watts. The most PSU heavy is your GPU, that's all you have to focus on because everything else sucks up little power. Your GPU demands a 450W PSU minimum, add 50Ws to that & that's the least amount of watts you need. A 600W PSU will be good, 750Ws will result in poor power efficiency.

Oh wow, thanks a lot! :D  The only PSU from Enermax I could fine near 600 watts was a 650 watt PSU though, if you think it's fine then I'll go ahead and get it.

Can you give me the model? I just wanna see so I can ensure you're getting a quality one - some of these companies have different PSUs made by different guys so, I just wanna make sure. Also, XFX has some nice 550W & 650W PSUs if you're interested for a good price.

Well personally, I'm an XFX guy, I like all their products plus, all their PSUs are made by the best manufacturer, SeaSonic, so when you get an XFX one it's a purely amazing PSU. The Enermax PSU you were looking at is made by Channel Well, which, quality is ehh - it can be good or bad from what I've seen. Personally I'd go with the XFX just because of the quality & design, but it also depends on how much you're willing to spend, if it goes with your case design layout & color scheme, and it matters if you ever wanna do an SLI config.

I'll be going with XFX then. :)  Thank all of you for your wonderful help.
