[Solved] Need help on a power supply

Hello im building a new computer its a budget computer pretty much and i cant find a power supply that would be good enough i would usually find one i think is good then i read the reviews and its alot of bad reviews and if i find one with good reviews it costs like 160 for like a 650 watt which is just way out of my budget and is single 12v rail or multiple rails better

Im using an i5
msi p55 gd65 motherboard http://www.newegg.com/Product/Prod [...] 6813130239
4gb GSkill 1600 ddr3 http://www.newegg.com/Product/Prod [...] 6820231279
2 western digital 750 hd
A samsung dvd burner
Im thinking of getting either a 4890 or a 5770 im not really a heavy gamer so im not gonna be playing crysis on like 2560x1600 but i do like some 3d modeling so not something to slow

also what is raid 0 and does it help much

Those look nice and closer to my budget do u have a good one thats not modular that usually seems to add like 20-30 dollars to the price and i dont mind a couple extra cables in the case

i looked at this one http://www.tigerdirect.com/applica [...] =A406-1116
most of the reviews on it look good but i dont really know much about xion

Thanks that one looks good ill get it

If any of you guys know anything about tv tuner cards that would help me out alot too because most of the ones under 250 that i see are bad reviews and driver problems are there any tv tuners 100 and under you would recommend i will be using windows 7 with this computer

maybe in the distant future but for now one graphics card would do me fine

and it dont know if running a second graphics card on that motherboard would work right because it splits the slots down to x8,x8

Modular doesn't really add that much to the cost anymore.
