Also I see alot of websites recommending the OCZ 750 Watt Fatal1ty but a lot of ppl hating on it. so whats the deal with that? Again I like it due to various sites rec and the red led which will go with the rest of my case. I also thought 750 W would be better when i OC or grab extra stuff for my PC.
but then again am pretty much a noob at this, and the whole 12v and rails stuff is always thrown out so casually without explanation. So if you could further help me in that matter i would be grateful.
The Antec HCG 620 recommended by amuffin is also a great power supply. It's made by Seasonic and while not reviewed by HardwareSecrets it does get a 9+ from HardwareHeaven. Most people think Seasonic makes the best consumer power supplies overall.
As stated above you don't need even close to a 750w power supply unless you plan on running 2 xHD 7850s in Corssfire. 550 watts is fine for a system with any single graphics card. A single HD 7850 only needs a 450w power supply as recommended by AMD and that assumes a generic middling quality unit.
If you want an excellent red themed case the Antec DF 85 is worth considering. It's expensive but is on a great sale right now. I have the similar Antec 1200 and it's an amazing case. The DF 85 is newer and has some really cool features not found on my 1200.
You don't even need a 750W for CF of the 7850s. A system with a 7850 uses about 250W at full load and that's with a highly overclocked, power-hungry i7-965; Nubzy's efficient 3570K with a moderate OC to 4.5 will consume less power. The XFX Core 550w with 44A on the 12V rail is enough for a CF of 7850s and a moderate OC.
