Argosax:Oh, so it's a low quality PSU? How can you tell? Just wondering so I'll be able to in the future.
well, I wouldn't exactly call that a low quality power supply. I think SergeiV was noting that there do seem to be a fair percentage of lower ratings on newegg for that power supply. However, there is a great review of an OCZ EvoStream power supply at jonnyguru.com. The only complaints that they noted in the review is that the fan noise is loud and that it is expensive. However, for $54 that's actually a very good deal.
Here's some of what was posted in the review of the evostream:
jonnyguru.com: the voltage regulation is fantastic. Especially for a modular power
supply which is going to exhibit voltage drop simply due to the fact
that there's additional resistance created by the modular interface.
jonnyguru.com: The power supply has rock solid rails and active PFC.
jonnyguru.com: At around $170, it's more expensive than most power supplies, even
modular power supplies. Yes, it's built like a tank. Yes, it will
likely last forever. So if you can quantify sheer girth with a dollar
amount, perhaps $170 is a fair price.
jonnyguru.com: It's hard not to love the EvoStream. It's like a Reese's Peanut Butter
Cup. "Hey! You got a server power supply in my modular gamer power
supply!"
Looking at the reviews, it seems that a couple people received DOA power supplies, a couple other people though that the cable sleeves were too stiff(and rated the power supply down for that), and one person recieved one that wasn't regulating power properly. As with any power supply, there will be defective units. It's hard to say if the defective unit percentage is significantly higher than most other power supplies, due to the low total number of user posted reviews.
Personally, I would get one of those, if the noise wouldn't be too much of a bother. They are nice server quality power supplies with high quality internal components, as was noted in the jonnyguru review, and for $55 it is a great price.
As for how to tell if a power supply is good or not, you should try searching the web for high quality reviews. A high quality review is a review in which the power supply is loaded up to various load levels, including it's max rated wattage. Voltage readings of the rails should be taken at each load level, as well as efficiency measurements.
If a review just hooks the power supply up to a computer, and checks the voltages at load and idle, that review really won't tell you much about the quality of the power supply. Chances are, the computer that they loaded it up with is not equal to the total rated wattage of the power supply, so there's no way to tell if the power supply is rated honestly or not.
Also, reviews should check the ripple on the 5v, 3.3v, and 12v rails at each load level. Many reviews do not check for this, and ripple can slowly destroy the voltage regulators on your motherboard and video card if it is too high(over ATX specs) for too long.
The best places to start looking for good reviews are the following websites: jonnyguru.com, hardocp.com, and hardwaresecrets.com. I think that anandtech also does pretty good power supply reviews as well.
If you can't find a good review of a certain power supply, you can always post it up on these forums, and we can dig up some information for you.

did you already purchase all of these items? If you didn't, there are certainly better RAM and video card deals out right now. I can post links if you're interested.
Argosax:Would there be a better PSU for this system then? I'm looking for a PSU in the $60-79.99 range, would be perfect. I'm fairly new to building my own rigs, and I was doubtful that the PSU would fit into the case as well (just to show my "noobness") :p
*Edit*
I'm looking at this one and it seems to fit what I want. Opinions on it?
well, that is an OK power supply. Rosewill is essentially Newegg's in house brand, and some of their power supply models are pretty good budget units. However, their RP series power supplies use lower quality capacitors that will fail if they are exposed to higher temperatures. Also, at $70 that really isn't a good deal. If you'd like to read about that power supply, there is a good review up of the 500watt Rosewill RP500-v2 power supply at jonnyguru.com.
Also, your system does not need 600watts of power. In order to figure out how much power your computer actually needs, you just add up all the max draw wattages each of your components are rated for.
In your case:
CPU: 65watts
GPU: 108watts
optical drive: 25watts
hard drive: 10watts
motherboard: 50watts
cooling, PCI cards, RAM, etc...: 50watts
total: 308watts
so, any good-quality 430watt power supply or higher should run your computer fine.
Currently, the Antec Earthwatts 430watt power supply is on sale for $30 w/ free shipping at newegg.com. It's a high quality power supply made by seasonic. It has high efficiency and a quiet fan. You can read a review of an Antec Earthwatts power supply at Jonnyguru.com. However, you couldn't really do too many upgrades with this power supply, and SLI is certainly out. You could add a couple hard drives without a problem, or put, say, an ATI Radeon 4850 graphics card in.
Also, you can currently get the OCZ StealthXStream 500watt power supply for $30 w/ free shipping at newegg.com. Use the coupon code EMCAGCGBD to get the $30 price. It's a good power supply selling for a great price, although it does have a louder fan than the Antec Earthwatts. If you'd like to read more about it, there is a great review of an OCZ StealthXStream up at HardwareSecrets.com.
If you'd like more power, the OCZ GameXStream 600watt power supply is currently on sale for $50 + shipping. It, like the above StealthXStream 500watt power supply, is a very nice PSU. In fact, during testing at Hardware Secrets of the StealthXStream 600watt PSU(almost identical to the GameXStream line, built on the same platform), they found that it can actually put out 728watts without a problem, which is really amazing for a power supply rated at 600watts.
Good luck on the build. If you have any other questions, don't hesitate to ask them.
