I'd stick to Antec, Corsair, Seasonic, and XFX if I didn't want to bother reading reviews (Thermaltake and OCZ are hit-and-miss).
If you're not gonna get a graphics card that uses more than 1 auxiliary connector (6870 or weaker), then a Corsair CX430 will get the job done just fine for you and is typically $20 after $20 rebate. Sometimes it's $5 cheaper or more expensive. (Or right now it's $35, which is unusually high).
I found this Antec 620W Neo Eco for $30 after rebate a couple weeks ago:http://www.newegg.com/Product/Product.aspx?Item=N82E16817371031
It's $73 now, so you want to look for deals.
EDIT: Aside from just Brand Name, you want to look at the Amperage on the +12V rail. Volts x Amps = Wattage. It's more complicated with multiple +12V rails because how they add up depends on circuitry. You'll see with that Coolermaster you linked that it actually only has 360W on the +12V rail (see label in images). That means it should be rated for about 400W. The Corsair CX430 has 25A on the +12V rail, or 336W, which means it should be about 375W, which is why people compare it to the Antec EA-380D, which also allows 336W on it's +12V rails according to its label.
A better built PSU not only has to provide enough power, but it provides it consistently as fluctuating currents and voltages can damage components.
